Bump version to v3.0.0 preview 3

The problem was that Catch2 did not reliably include `<exception>`
before it checked for the feature test macro for
`std::uncaught_exceptions`. To avoid overhead of including
`<exception>` everywhere, the configuration check was split out
into a separate header.

Closes #2021

 Catch is designed to "just work" as much as possible. For most people the only configuration needed is telling Catch which source file should host all the implementation code (```CATCH_CONFIG_MAIN```).
 
 Nonetheless there are still some occasions where finer control is needed. For these occasions Catch exposes a set of macros for configuring how it is built.
 
-## main()/ implementation
-
-    CATCH_CONFIG_MAIN      // Designates this as implementation file and defines main()
-    CATCH_CONFIG_RUNNER    // Designates this as implementation file
-
-Although Catch is header only it still, internally, maintains a distinction between interface headers and headers that contain implementation. Only one source file in your test project should compile the implementation headers and this is controlled through the use of one of these macros - one of these identifiers should be defined before including Catch in *exactly one implementation file in your project*.
-
-## Reporter / Listener interfaces
-
-    CATCH_CONFIG_EXTERNAL_INTERFACES  // Brings in necessary headers for Reporter/Listener implementation
-
-Brings in various parts of Catch that are required for user defined Reporters and Listeners. This means that new Reporters and Listeners can be defined in this file as well as in the main file.

-Implied by both `CATCH_CONFIG_MAIN` and `CATCH_CONFIG_RUNNER`.

+So you want to contribute something to Catch2? That's great! Whether it's
+a bug fix, a new feature, support for additional compilers - or just
+a fix to the documentation - all contributions are very welcome and very
+much appreciated. Of course so are bug reports, other comments, and
+questions, but generally it is a better idea to ask questions in our
+[Discord](https://discord.gg/4CWS9zD), than in the issue tracker.
 
-If you are contributing to the code base there are a few simple guidelines to keep in mind. This also includes notes to
-help you find your way around. As this is liable to drift out of date please raise an issue or, better still, a pull
-request for this file, if you notice that.
 
-## Branches
+This page covers some guidelines and helpful tips for contributing
+to the codebase itself.
 
-Ongoing development is currently on _master_. At some point an integration branch will be set-up and PRs should target
- that - but for now it's all against master. You may see feature branches come and go from time to time, too.
+## Using Git(Hub)
 
-## Directory structure
+Ongoing development happens in the `devel` branch for Catch2 v3, and in
+`v2.x` for maintenance updates to the v2 versions.
 
-_Users_ of Catch primarily use the single header version. _Maintainers_ should work with the full source (which is still,
-primarily, in headers). This can be found in the `include` folder. There are a set of test files, currently under
-`projects/SelfTest`. The test app can be built via CMake from the `CMakeLists.txt` file in the root, or you can generate
-project files for Visual Studio, XCode, and others (instructions in the `projects` folder). If you have access to CLion,
-it can work with the CMake file directly.
+Commits should be small and atomic. A commit is atomic when, after it is
+applied, the codebase, tests and all, still works as expected. Small
+commits are also prefered, as they make later operations with git history,
+whether it is bisecting, reverting, or something else, easier.
 
-As well as the runtime test files you'll also see a `SurrogateCpps` directory under `projects/SelfTest`.
-This contains a set of .cpp files that each `#include` a single header.
-While these files are not essential to compilation they help to keep the implementation headers self-contained.
-At time of writing this set is not complete but has reasonable coverage.
-If you add additional headers please try to remember to add a surrogate cpp for it.
+_When submitting a pull request please do not include changes to the
+amalgamated distribution files. This means do not include them in your
+git commits!_
 
-The other directories are `scripts` which contains a set of python scripts to help in testing Catch as well as
-generating the single include, and `docs`, which contains the documentation as a set of markdown files.
+When addressing review comments in a MR, please do not rebase/squash the
+commits immediately. Doing so makes it harder to review the new changes,
+slowing down the process of merging a MR. Instead, when addressing review
+comments, you should append new commits to the branch and only squash
+them into other commits when the MR is ready to be merged. We recommend
+creating new commits with `git commit --fixup` (or `--squash`) and then
+later squashing them with `git rebase --autosquash` to make things easier.
 
-__When submitting a pull request please do not include changes to the single include, or to the version number file
-as these are managed by the scripts!__
 
 
 ## Testing your changes
 
-Obviously all changes to Catch's code should be tested. If you added new
-functionality, you should add tests covering and showcasing it. Even if you have
-only made changes to Catch internals (i.e. you implemented some performance
-improvements), you should still test your changes.
+_Note: Running Catch2's tests requires Python3_
 
-This means 2 things
 
-* Compiling Catch's SelfTest project:
+Catch2 has multiple layers of tests that are then run as part of our CI.
+The most obvious one are the unit tests compiled into the `SelfTest`
+binary. These are then used in "Approval tests", which run (almost) all
+tests from `SelfTest` through a specific reporter and then compare the
+generated output with a known good output ("Baseline"). By default, new
+tests should be placed here.
+
+However, not all tests can be written as plain unit tests. For example,
+checking that Catch2 orders tests randomly when asked to, and that this
+random ordering is subset-invariant, is better done as an integration
+test using an external check script. Catch2 integration tests are written
+using CTest, either as a direct command invocation + pass/fail regex,
+or by delegating the check to a Python script.
+
+There are also two more kinds of tests, examples and "ExtraTests".
+Examples present a small and self-contained snippets of code that
+use Catch2's facilities for specific purpose. Currently they are assumed
+passing if they compile. ExtraTests then are expensive tests, that we
+do not want to run all the time. This can be either because they take
+a long time to run, or because they take a long time to compile, e.g.
+because they test compile time configuration and require separate
+compilation.
+
+Examples and ExtraTests are not compiled by default. To compile them,
+add `-DCATCH_BUILD_EXAMPLES=ON` and `-DCATCH_BUILD_EXTRA_TESTS=ON` to
+the invocation of CMake configuration step.
+
+Bringing this all together, the steps below should configure, build,
+and run all tests in the `Debug` compilation.
+
+1. Regenerate the amalgamated distribution
 ```
 $ cd Catch2
-$ cmake -Bdebug-build -H. -DCMAKE_BUILD_TYPE=Debug
+$ ./tools/scripts/generateAmalgamatedFiles.py
+```
+2. Configure the full test build
+```
+$ cmake -Bdebug-build -H. -DCMAKE_BUILD_TYPE=Debug -DCATCH_BUILD_EXAMPLES=ON -DCATCH_BUILD_EXTRA_TESTS=ON
+```
+3. Run the actual build
+```
 $ cmake --build debug-build
 ```
-because code that does not compile is evidently incorrect. Obviously,
-you are not expected to have access to all the compilers and platforms
-supported by Catch2, but you should at least smoke test your changes
-on your platform. Our CI pipeline will check your PR against most of
-the supported platforms, but it takes an hour to finish -- compiling
-locally takes just a few minutes.
-
-
-* Running the tests via CTest:
+4. Run the tests using CTest
 ```
 $ cd debug-build
-$ ctest -j 2 --output-on-failure
+$ ctest -j 4 --output-on-failure -C Debug
 ```
-If you added new tests, approval tests are very likely to fail. If they
-do not, it means that your changes weren't run as part of them. This
-_might_ be intentional, but usually is not.
 
-The approval tests compare current output of the SelfTest binary in various
-configurations against known good outputs. The reason it fails is,
-_usually_, that you've added new tests but have not yet approved the changes
-they introduce. This is done with the `scripts/approve.py` script, but
-before you do so, you need to check that the introduced changes are indeed
-intentional.
+If you added new tests, you will likely see `ApprovalTests` failure.
+After you check that the output difference is expected, you should
+run `tools/scripts/approve.py` to confirm them, and include these changes
+in your commit.
 
 
-## Documenting your code
+## Writing documentation
 
 If you have added new feature to Catch2, it needs documentation, so that
 other people can use it as well. This section collects some technical
 information that you will need for updating Catch2's documentation, and
 possibly some generic advise as well.

+### Contents
 
-Now, for the generic tips:
-  * Usage examples are good
-  * Don't be afraid to introduce new pages
-  * Try to be reasonably consistent with the surrounding documentation
+Now, for some content tips:
+
+* Usage examples are good. However, having large code snippets inline
+can make the documentation less readable, and so the inline snippets
+should be kept reasonably short. To provide more complex compilable
+examples, consider adding new .cpp file to `examples/`.
+
+* Don't be afraid to introduce new pages. The current documentation
+tends towards long pages, but a lot of that is caused by legacy, and
+we know that some of the pages are overly big and unfocused.
+
+* When adding information to an existing page, please try to keep your
+formatting, style and changes consistent with the rest of the page.
+
+* Any documentation has multiple different audiences, that desire
+different information from the text. The 3 basic user-types to try and
+cover are:
+  * A beginner to Catch2, who requires closer guidance for the usage of Catch2.
+  * Advanced user of Catch2, who want to customize their usage.
+  * Experts, looking for full reference of Catch2's capabilities.
 
 
+## Writing code
+
+If want to contribute code, this section contains some simple rules
+and tips on things like code formatting, code constructions to avoid,
+and so on.
 
 
-## Code constructs to watch out for
+### Formatting
+
+To make code formatting simpler for the contributors, Catch2 provides
+its own config for `clang-format`. However, because it is currently
+impossible to replicate existing Catch2's formatting in clang-format,
+using it to reformat a whole file would cause massive diffs. To keep
+the size of your diffs reasonable, you should only use clang-format
+on the newly changed code.

-----
+### New source file template
+
+If you are adding new source file, there is a template you should use.
+Specifically, every source file should start with the licence header:
+```cpp
+
+    //              Copyright Catch2 Authors
+    // Distributed under the Boost Software License, Version 1.0.
+    //   (See accompanying file LICENSE_1_0.txt or copy at
+    //        https://www.boost.org/LICENSE_1_0.txt)
+
+    // SPDX-License-Identifier: BSL-1.0
+```
+
+The include guards for header files should follow the pattern `{FILENAME}_INCLUDED`.
+This means that for file `catch_matchers_foo`, the include guard should
+be `CATCH_MATCHERS_FOO_INCLUDED`, for `catch_generators_bar`, the include
+guard should be `CATCH_GENERATORS_BAR_INCLUDED`, and so on.

-The assertion in this test case will be run 9 times, because there
-are 3 possible values for `i` (1, 2, and 3) and there are 3 possible
-values for `j` (-3, -2, and -1).
+The "Generators" `TEST_CASE` will be entered 3 times, and the value of
+`i` will be 1, 3, and 5 in turn. `GENERATE`s can also be used multiple
+times at the same scope, in which case the result will be a cartesian
+product of all elements in the generators. This means that in the snippet
+below, the test case will be run 6 (2\*3) times.
 
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    auto j = GENERATE(3, 4, 5);
+}
+```
 
 There are 2 parts to generators in Catch2, the `GENERATE` macro together
 with the already provided generators, and the `IGenerator<T>` interface
 that allows users to implement their own generators.
 
+
+## Combining `GENERATE` and `SECTION`.
+
+`GENERATE` can be seen as an implicit `SECTION`, that goes from the place
+`GENERATE` is used, to the end of the scope. This can be used for various
+effects. The simplest usage is shown below, where the `SECTION` "one"
+runs 4 (2\*2) times, and `SECTION` "two" is run 6 times (2\*3).
+
+```cpp
+TEST_CASE("Generators") {
+    auto i = GENERATE(1, 2);
+    SECTION("one") {
+        auto j = GENERATE(-3, -2);
+        REQUIRE(j < i);
+    }
+    SECTION("two") {
+        auto k = GENERATE(4, 5, 6);
+        REQUIRE(i != k);
+    }
+}
+```
+
+The specific order of the `SECTION`s will be "one", "one", "two", "two",
+"two", "one"...
+
+
+The fact that `GENERATE` introduces a virtual `SECTION` can also be used
+to make a generator replay only some `SECTION`s, without having to
+explicitly add a `SECTION`. As an example, the code below reports 3
+assertions, because the "first" section is run once, but the "second"
+section is run twice.
+
+```cpp
+TEST_CASE("GENERATE between SECTIONs") {
+    SECTION("first") { REQUIRE(true); }
+    auto _ = GENERATE(1, 2);
+    SECTION("second") { REQUIRE(true); }
+}
+```
+
+This can lead to surprisingly complex test flows. As an example, the test
+below will report 14 assertions:
+
+```cpp
+TEST_CASE("Complex mix of sections and generates") {
+    auto i = GENERATE(1, 2);
+    SECTION("A") {
+        SUCCEED("A");
+    }
+    auto j = GENERATE(3, 4);
+    SECTION("B") {
+        SUCCEED("B");
+    }
+    auto k = GENERATE(5, 6);
+    SUCCEED();
+}

 # Matchers
 
-Matchers are an alternative way to do assertions which are easily extensible and composable.
-This makes them well suited to use with more complex types (such as collections) or your own custom types.
-Matchers were first popularised by the [Hamcrest](https://en.wikipedia.org/wiki/Hamcrest) family of frameworks.

-## In use
+Matchers, as popularized by the [Hamcrest](https://en.wikipedia.org/wiki/Hamcrest)
+framework are an alternative way to write assertions, useful for tests
+where you work with complex types or need to assert more complex
+properties. Matchers are easily composable and users can write their
+own and combine them with the Catch2-provided matchers seamlessly.
 
-Matchers are introduced with the `REQUIRE_THAT` or `CHECK_THAT` macros, which take two arguments.
-The first argument is the thing (object or value) under test. The second part is a match _expression_,
-which consists of either a single matcher or one or more matchers combined using `&&`, `||` or `!` operators.
 
-For example, to assert that a string ends with a certain substring:
+## Using Matchers
 
- ```c++
-using Catch::Matchers::EndsWith; // or Catch::EndsWith
-std::string str = getStringFromSomewhere();
-REQUIRE_THAT( str, EndsWith( "as a service" ) );
- ```
+Matchers are most commonly used in tandem with the `REQUIRE_THAT` or
+`CHECK_THAT` macros. The `REQUIRE_THAT` macro takes two arguments,
+the first one is the input (object/value) to test, the second argument
+is the matcher itself.
 
-The matcher objects can take multiple arguments, allowing more fine tuning.
-The built-in string matchers, for example, take a second argument specifying whether the comparison is
-case sensitive or not:
+For example, to assert that a string ends with the "as a service"
+substring, you can write the following assertion
 
-```c++
-REQUIRE_THAT( str, EndsWith( "as a service", Catch::CaseSensitive::No ) );
- ```
+```cpp
+using Catch::Matchers::EndsWith;
 
-And matchers can be combined:
-
-```c++
-REQUIRE_THAT( str,
-    EndsWith( "as a service" ) ||
-    (StartsWith( "Big data" ) && !Contains( "web scale" ) ) );
+REQUIRE_THAT( getSomeString(), EndsWith("as a service") );
 ```
 
-## Built in matchers
-Catch2 provides some matchers by default. They can be found in the
-`Catch::Matchers::foo` namespace and are imported into the `Catch`
-namespace as well.
+Individual matchers can also be combined using the C++ logical
+operators, that is `&&`, `||`, and `!`, like so:
 
-There are two parts to each of the built-in matchers, the matcher
-type itself and a helper function that provides template argument
-deduction when creating templated matchers. As an example, the matcher
-for checking that two instances of `std::vector` are identical is
-`EqualsMatcher<T>`, but the user is expected to use the `Equals`
-helper function instead.
+```cpp
+using Catch::Matchers::EndsWith;
+using Catch::Matchers::Contains;
+
+REQUIRE_THAT( getSomeString(),
+              EndsWith("as a service") && Contains("web scale"));
+```
+
+The example above asserts that the string returned from `getSomeString`
+_both_ ends with the suffix "as a service" _and_ contains the string
+"web scale" somewhere.
 
 
-### String matchers
-The string matchers are `StartsWith`, `EndsWith`, `Contains`, `Equals` and `Matches`. The first four match a literal (sub)string against a result, while `Matches` takes and matches an ECMAScript regex. Do note that `Matches` matches the string as a whole, meaning that "abc" will not match against "abcd", but "abc.*" will.
+Both of the string matchers used in the examples above live in the
+`catch_matchers_string.hpp` header, so to compile the code above also
+requires `#include <catch2/matchers/catch_matchers_string.hpp>`.
 
-Each of the provided `std::string` matchers also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).
+**IMPORTANT**: The combining operators do not take ownership of the
+matcher objects being combined. This means that if you store combined
+matcher object, you have to ensure that the matchers being combined
+outlive its last use. What this means is that the following code leads
+to a use-after-free (UAF):
+
+```cpp
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/matchers/catch_matchers_string.h>
+
+TEST_CASE("Bugs, bugs, bugs", "[Bug]"){
+    std::string str = "Bugs as a service";
+
+    auto match_expression = Catch::Matchers::EndsWith( "as a service" ) ||
+        (Catch::Matchers::StartsWith( "Big data" ) && !Catch::Matchers::Contains( "web scale" ) );
+    REQUIRE_THAT(str, match_expression);
+}
+```
+
+
+## Built-in matchers
+
+Every matcher provided by Catch2 is split into 2 parts, a factory
+function that lives in the `Catch::Matchers` namespace, and the actual
+matcher type that is in some deeper namespace and should not be used by
+the user. In the examples above, we used `Catch::Matchers::Contains`.
+This is the factory function for the
+`Catch::Matchers::StdString::ContainsMatcher` type that does the actual
+matching.
+
+Out of the box, Catch2 provides the following matchers:
+
+
+### `std::string` matchers
+
+Catch2 provides 5 different matchers that work with `std::string`,
+* `StartsWith(std::string str, CaseSensitive)`,
+* `EndsWith(std::string str, CaseSensitive)`,
+* `Contains(std::string str, CaseSensitive)`,
+* `Equals(std::string str, CaseSensitive)`, and
+* `Matches(std::string str, CaseSensitive)`.
+
+The first three should be fairly self-explanatory, they succeed if
+the argument starts with `str`, ends with `str`, or contains `str`
+somewhere inside it.
+
+The `Equals` matcher matches a string if (and only if) the argument
+string is equal to `str`.
+
+Finally, the `Matches` matcher performs an ECMASCript regex match using
+`str` against the argument string. It is important to know that
+the match is performed agains the string as a whole, meaning that
+the regex `"abc"` will not match input string `"abcd"`. To match
+`"abcd"`, you need to use e.g. `"abc.*"` as your regex.
+
+The second argument sets whether the matching should be case-sensitive
+or not. By default, it is case-sensitive.
+
+> `std::string` matchers live in `catch2/matchers/catch_matchers_string.hpp`
 
 
 ### Vector matchers
-Catch2 currently provides 5 built-in matchers that work on `std::vector`.
+
+_Vector matchers have been deprecated in favour of the generic
+range matchers with the same functionality._

+
 
 ### Floating point matchers
-Catch2 provides 3 matchers for working with floating point numbers. These
-are `WithinAbsMatcher`, `WithinUlpsMatcher` and `WithinRelMatcher`.
 
-The `WithinAbsMatcher` matcher accepts floating point numbers that are
-within a certain distance of target. It should be constructed with the
-`WithinAbs(double target, double margin)` helper.
+Catch2 provides 3 matchers that target floating point numbers. These
+are:
 
-The `WithinUlpsMatcher` matcher accepts floating point numbers that are
-within a certain number of [ULPs](https://en.wikipedia.org/wiki/Unit_in_the_last_place)
-of the target. Because ULP comparisons need to be done differently for
-`float`s and for `double`s, there are two overloads of the helpers for
-this matcher, `WithinULP(float target, int64_t ULPs)`, and
-`WithinULP(double target, int64_t ULPs)`.
-
-The `WithinRelMatcher` matcher accepts floating point numbers that are
-_approximately equal_ with the target number with some specific tolerance.
-In other words, it checks that `|lhs - rhs| <= epsilon * max(|lhs|, |rhs|)`,
-with special casing for `INFINITY` and `NaN`. There are _4_ overloads of
-the helpers for this matcher, `WithinRel(double target, double margin)`,
-`WithinRel(float target, float margin)`, `WithinRel(double target)`, and
-`WithinRel(float target)`. The latter two provide a default epsilon of
-machine epsilon * 100.
+* `WithinAbs(double target, double margin)`,
+* `WithinUlps(FloatingPoint target, uint64_t maxUlpDiff)`, and
+* `WithinRel(FloatingPoint target, FloatingPoint eps)`.
 
 > `WithinRel` matcher was introduced in Catch 2.10.0
 
-### Generic matchers
-Catch also aims to provide a set of generic matchers. Currently this set
-contains only a matcher that takes arbitrary callable predicate and applies
-it onto the provided object.
 
-Because of type inference limitations, the argument type of the predicate
-has to be provided explicitly. Example:
+`WithinAbs` creates a matcher that accepts floating point numbers whose
+difference with `target` is less than the `margin`.
+
+`WithinULP` creates a matcher that accepts floating point numbers that
+are no more than `maxUlpDiff`
+[ULPs](https://en.wikipedia.org/wiki/Unit_in_the_last_place)
+away from the `target` value. The short version of what this means
+is that there is no more than `maxUlpDiff - 1` representeable floating
+point numbers between the argument for matching and the `target` value.
+
+`WithinRel` creates a matcher that accepts floating point numbers that
+are _approximately equal_ with the `target` with tolerance of `eps.`
+Specifically, it matches if
+`|arg - target| <= eps * max(|arg|, |target|)` holds. If you do not
+specify `eps`, `std::numeric_limits<FloatingPoint>::epsilon * 100`
+is used as the default.
+
+
+In practice, you will often want to combine multiple of these matchers,
+together for an assertion, because all 3 options have edge cases where
+they behave differently than you would expect. As an example, under
+the `WithinRel` matcher, a `0.` only ever matches a `0.` (or `-0.`),
+regardless of the relative tolerance specified. Thus, if you want to
+handle numbers that are "close enough to 0 to be 0", you have to combine
+it with the `WithinAbs` matcher.
+
+For example, to check that our computation matches known good value
+within 0.1%, or is close enough (no different to 5 decimal places)
+to zero, we would write this assertion:
+```cpp
+    REQUIRE_THAT( computation(input),
+        Catch::Matchers::WithinRel(expected, 0.001)
+     || Catch::Matchers::WithinAbs(0, 0.000001) );
+```
+
+
+> floating point matchers live in `catch2/matchers/catch_matchers_floating.hpp`
+
+
+### Miscellaneous matchers
+
+Catch2 also provides some matchers and matcher utilities that do not
+quite fit into other categories.
+
+The first one of them is the `Predicate(Callable pred, std::string description)`
+matcher. It creates a matcher object that calls `pred` for the provided
+argument. The `description` argument allows users to set what the
+resulting matcher should self-describe as if required.
+
+Do note that you will need to explicitly specify the type of the
+argument, like in this example:
+
 ```cpp
 REQUIRE_THAT("Hello olleH",
              Predicate<std::string>(
@@ -107,84 +211,205 @@ REQUIRE_THAT("Hello olleH",
 );
 ```
 
-The second argument is an optional description of the predicate, and is
-used only during reporting of the result.
+> the predicate matcher lives in `catch2/matchers/catch_matchers_predicate.hpp`
 
 
-### Exception matchers
-Catch2 also provides an exception matcher that can be used to verify
-that an exception's message exactly matches desired string. The matcher
-is `ExceptionMessageMatcher`, and we also provide a helper function
-`Message`.
+The other miscellaneous matcher utility is exception matching.
 
-The matched exception must publicly derive from `std::exception` and
-the message matching is done _exactly_, including case.
 
-> `ExceptionMessageMatcher` was introduced in Catch 2.10.0
+#### Matching exceptions
+
+Catch2 provides an utility macro for asserting that an expression
+throws exception of specific type, and that the exception has desired
+properties. The macro is `REQUIRE_THROWS_MATCHES(expr, ExceptionType, Matcher)`.
+
+> `REQUIRE_THROWS_MATCHES` macro lives in `catch2/matchers/catch_matchers.hpp`
+
+
+Catch2 currently provides only one matcher for exceptions,
+`Message(std::string message)`. `Message` checks that the exception's
+message, as returned from `what` is exactly equal to `message`.
 
 Example use:
 ```cpp
 REQUIRE_THROWS_MATCHES(throwsDerivedException(),  DerivedException,  Message("DerivedException::what"));
 ```
 
-## Custom matchers
-It's easy to provide your own matchers to extend Catch or just to work with your own types.
+Note that `DerivedException` in the example above has to derive from
+`std::exception` for the example to work.
 
-You need to provide two things:
-1. A matcher class, derived from `Catch::MatcherBase<T>` - where `T` is the type being tested.
-The constructor takes and stores any arguments needed (e.g. something to compare against) and you must
-override two methods: `match()` and `describe()`.
-2. A simple builder function. This is what is actually called from the test code and allows overloading.
+> the exception message matcher lives in `catch2/matchers/catch_matchers_exception.hpp`
 
-Here's an example for asserting that an integer falls within a given range
-(note that it is all inline for the sake of keeping the example short):
+
+### Generic range Matchers
+
+> Generic range matchers were introduced in Catch X.Y.Z
+
+Catch2 also provides some matchers that use the new style matchers
+definitions to handle generic range-like types. These are:
+
+* `IsEmpty()`
+* `SizeIs(size_t target_size)`
+* `SizeIs(Matcher size_matcher)`
+* `Contains(T&& target_element, Comparator = std::equal_to<>{})`
+* `Contains(Matcher element_matcher)`
+
+`IsEmpty` should be self-explanatory. It successfully matches objects
+that are empty according to either `std::empty`, or ADL-found `empty`
+free function.
+
+`SizeIs` checks range's size. If constructed with `size_t` arg, the
+matchers accepts ranges whose size is exactly equal to the arg. If
+constructed from another matcher, then the resulting matcher accepts
+ranges whose size is accepted by the provided matcher.
+
+`Contains` accepts ranges that contain specific element. There are
+again two variants, one that accepts the desired element directly,
+in which case a range is accepted if any of its elements is equal to
+the target element. The other variant is constructed from a matcher,
+in which case a range is accepted if any of its elements is accepted
+by the provided matcher.
+
+
+## Writing custom matchers (old style)
+
+The old style of writing matchers has been introduced back in Catch
+Classic. To create an old-style matcher, you have to create your own
+type that derives from `Catch::Matchers::MatcherBase<ArgT>`, where
+`ArgT` is the type your matcher works for. Your type has to override
+two methods, `bool match(ArgT const&) const`,
+and `std::string describe() const`.
+
+As the name suggests, `match` decides whether the provided argument
+is matched (accepted) by the matcher. `describe` then provides a
+human-oriented description of what the matcher does.
+
+We also recommend that you create factory function, just like Catch2
+does, but that is mostly useful for template argument deduction for
+templated matchers (assuming you do not have CTAD available).
+
+To combine these into an example, let's say that you want to write
+a matcher that decides whether the provided argument is a number
+within certain range. We will call it `IsBetweenMatcher<T>`:
 
 ```c++
-// The matcher class
-class IntRange : public Catch::MatcherBase<int> {
-    int m_begin, m_end;
-public:
-    IntRange( int begin, int end ) : m_begin( begin ), m_end( end ) {}
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/matchers/catch_matchers.h>
+// ...
 
-    // Performs the test for this matcher
-    bool match( int const& i ) const override {
-        return i >= m_begin && i <= m_end;
+
+template <typename T>
+class IsBetweenMatcher : public Catch::Matchers::MatcherBase<T> {
+    T m_begin, m_end;
+public:
+    IsBetweenMatcher(T begin, T end) : m_begin(begin), m_end(end) {}
+
+    bool match(T const& in) const override {
+        return in >= m_begin && in <= m_end;
     }
 
-    // Produces a string describing what this matcher does. It should
-    // include any provided data (the begin/ end in this case) and
-    // be written as if it were stating a fact (in the output it will be
-    // preceded by the value under test).
-    virtual std::string describe() const override {
+    std::string describe() const override {
         std::ostringstream ss;
         ss << "is between " << m_begin << " and " << m_end;
         return ss.str();
     }
 };
 
-// The builder function
-inline IntRange IsBetween( int begin, int end ) {
-    return IntRange( begin, end );
+template <typename T>
+IsBetweenMatcher<T> IsBetween(T begin, T end) {
+    return { begin, end };
 }
 
 // ...
 
-// Usage
-TEST_CASE("Integers are within a range")
-{
-    CHECK_THAT( 3, IsBetween( 1, 10 ) );
-    CHECK_THAT( 100, IsBetween( 1, 10 ) );
+TEST_CASE("Numbers are within range") {
+    // infers `double` for the argument type of the matcher
+    CHECK_THAT(3., IsBetween(1., 10.));
+    // infers `int` for the argument type of the matcher
+    CHECK_THAT(100, IsBetween(1, 10));
 }
 ```
 
-Running this test gives the following in the console:
+Obviously, the code above can be improved somewhat, for example you
+might want to `static_assert` over the fact that `T` is an arithmetic
+type... or generalize the matcher to cover any type for which the user
+can provide a comparison function object.
 
+Note that while any matcher written using the old style can also be
+written using the new style, combining old style matchers should
+generally compile faster. Also note that you can combine old and new
+style matchers arbitrarily.
+
+> `MatcherBase` lives in `catch2/matchers/catch_matchers.hpp`
+
+
+## Writing custom matchers (new style)
+
+> New style matchers were introduced in Catch X.Y.Z
+
+To create a new-style matcher, you have to create your own type that
+derives from `Catch::Matchers::MatcherGenericBase`. Your type has to
+also provide two methods, `bool match( ... ) const` and overriden
+`std::string describe() const`.
+
+Unlike with old-style matchers, there are no requirements on how
+the `match` member function takes its argument. This means that the
+argument can be taken by value or by mutating reference, but also that
+the matcher's `match` member function can be templated.
+
+This allows you to write more complex matcher, such as a matcher that
+can compare one range-like (something that responds to `begin` and
+`end`) object to another, like in the following example:
+
+```cpp
+#include <catch2/catch_test_macros.hpp>
+#include <catch2/matchers/catch_matchers_templated.hpp>
+// ...
+
+template<typename Range>
+struct EqualsRangeMatcher : Catch::Matchers::MatcherGenericBase {
+    EqualsRangeMatcher(Range const& range):
+        range{ range }
+    {}
+
+    template<typename OtherRange>
+    bool match(OtherRange const& other) const {
+        using std::begin; using std::end;
+
+        return std::equal(begin(range), end(range), begin(other), end(other));
+    }
+
+    std::string describe() const override {
+        return "Equals: " + Catch::rangeToString(range);
+    }
+
+private:
+    Range const& range;
+};
+
+template<typename Range>
+auto EqualsRange(const Range& range) -> EqualsRangeMatcher<Range> {
+    return EqualsRangeMatcher<Range>{range};
+}
+
+TEST_CASE("Combining templated matchers", "[matchers][templated]") {
+    std::array<int, 3> container{{ 1,2,3 }};
+
+    std::array<int, 3> a{{ 1,2,3 }};
+    std::vector<int> b{ 0,1,2 };
+    std::list<int> c{ 4,5,6 };
+
+    REQUIRE_THAT(container, EqualsRange(a) || EqualsRange(b) || EqualsRange(c));
+}
 ```
-/**/TestFile.cpp:123: FAILED:
-  CHECK_THAT( 100, IsBetween( 1, 10 ) )
-with expansion:
-  100 is between 1 and 10
-```
+
+Do note that while you can rewrite any matcher from the old style to
+a new style matcher, combining new style matchers is more expensive
+in terms of compilation time. Also note that you can combine old style
+and new style matchers arbitrarily.

+## 3.0.1 (in progress)
+
+
+**Catch2 now uses statically compiled library as its distribution model.
+This also means that to get all of Catch2's functionality in a test file,
+you have to include multiple headers.**
+
+For quick'n'dirty migration, you can replace the old `#include <catch2/catch.hpp>`
+with `#include <catch2/catch_all.hpp>`. This is a (one of) convenience
+header(s) that brings in _all_ of headers in Catch2. By doing this,
+you should be able to migrate instantly, but at the cost of (significantly)
+increased compilation times. You should prefer piecemeal including
+headers that are actually required by your test code.
+
+The basic set of functionality (`TEST_CASE`, `SECTION`, `REQUIRE`) is in
+`catch2/catch_test_macros.hpp`. Matchers are in `matchers` subfolder,
+generators in `generators` subfolder, and so on.
+
+Note that documentation has not yet been updated to account for the
+new design.
+
+
+### FAQ
+
+* Why is Catch2 moving to separate headers?
+  * The short answer is future extensibility and scalability. The long answer is complex and can be found on my blog, but at the most basic level, it is that providing single-header distribution is at odds with providing variety of useful features. When Catch2 was distributed in a single header, adding a new Matcher would cause overhead for everyone, but was useful only to a subset of users. This meant that the barrier to entry for new Matchers/Generators/etc is high in single header model, but much smaller in the new model.
+* Will Catch2 again distribute single-header version in the future?
+  * No. But we do provide sqlite-style amalgamated distribution option. This means that you can download just 1 .cpp file and 1 header and place them next to your own sources. However, doing this has downsides similar to using the `catch_all.hpp` header.
+* Why the big breaking change caused by replacing `catch.hpp` with `catch_all.hpp`?
+  * The convenience header `catch_all.hpp` exists for two reasons. One of them is to provide a way for quick migration from Catch2, the second one is to provide a simple way to test things with Catch2. Using it for migration has one drawback in that it is **big**. This means that including it _will_ cause significant compile time drag, and so using it to migrate should be a concious decision by the user, not something they can just stumble into unknowingly.
+
+
+### (Potentially) Breaking changes
+* **Catch2 now uses statically compiled library as its distribution model**
+  * **Including `catch.hpp` no longer works**
+* `ANON_TEST_CASE` has been removed, use `TEST_CASE` with no arguments instead (#1220)
+* `--list*` commands no longer have non-zero return code (#1410)
+* `--list-test-names-only` has been removed (#1190)
+  * You should use verbosity-modifiers for `--list-tests` instead
+* `--list*` commands are now piped through the reporters
+  * The top-level reporter interface provides default implementation that works just as the old one
+  * XmlReporter outputs a machine-parseable XML
+* `TEST_CASE` description support has been removed
+  * If the second argument has text outside tags, the text will be ignored.
+* Hidden test cases are no longer included just because they don't match an exclusion tag
+  * Previously, a `TEST_CASE("A", "[.foo]")` would be included by asking for `~[bar]`.
+* `PredicateMatcher` is no longer type erased.
+  * This means that the type of the provided predicate is part of the `PredicateMatcher`'s type
+* `SectionInfo` no longer contains section description as a member (#1319)
+  * You can still write `SECTION("ShortName", "Long and wordy description")`, but the description is thrown away
+  * The description type now must be a `const char*` or be implicitly convertible to it
+* The `[!hide]` tag has been removed.
+  * Use `[.]` or `[.foo]` instead.
+* Lvalues of composed matchers cannot be composed further
+* Uses of `REGISTER_TEST_CASE` macro need to be followed by a semicolon
+  * This does not change `TEST_CASE` and friends in any way
+* `IStreamingReporter::IsMulti` member function was removed
+  * This is _very_ unlikely to actually affect anyone, as it was default-implemented in the interface, and only used internally
+* Various classes not designed for user-extension have been made final
+  * `ListeningReporter` is now `final`
+  * Concrete Matchers (e.g. `UnorderedEquals` vector matcher) are now `final`
+  * All Generators are now `final`
+* Matcher namespacing has been redone
+  * Matcher types are no longer in deeply nested namespaces
+  * Matcher factory functions are no longer brought into `Catch` namespace
+  * This means that all public-facing matcher-related functionality is now in `Catch::Matchers` namespace
+* Defining `CATCH_CONFIG_MAIN` will no longer create main in that TU.
+  * Link with `libCatch2Main.a`, or the proper CMake/pkg-config target
+  * If you want to write custom main, include `catch2/catch_session.hpp`
+* `CATCH_CONFIG_EXTERNAL_INTERFACES` has been removed.
+  * You should instead include the appropriate headers as needed.
+* `CATCH_CONFIG_IMPL` has been removed.
+  * The implementation is now compiled into a static library.
+* Event Listener interface has changed
+  * `TestEventListenerBase` was renamed to `EventListenerBase`
+  * `EventListenerBase` now directly derives from `IStreamingReporter`, instead of deriving from `StreamingReporterBase`
+
+
+
+### Improvements
+* Matchers have been extended with the ability to use different signatures of `match` (#1307, #1553, #1554, #1843)
+  * This includes having templated `match` member function
+  * See the [rewritten Matchers documentation](matchers.md#top) for details
+  * Catch2 currently provides _some_ generic matchers, but there should be more before final release of v3
+    * So far, `IsEmpty`, `SizeIs`, and `Contains` are provided.
+    * At least `ElementsAre` and `UnorderedElementsAre` are planned.
+* Some runtime performance improvements
+* Significant compilation time improvements
+  * including `catch_test_macros.hpp` is 80% cheaper than including `catch.hpp`
+
+
+### Fixes
+* The `INFO` macro no longer contains superfluous semicolon (#1456)
+* The `--list*` family of command line flags now return 0 on success (#1410, #1146)
+
+
+### Other changes
+* `CATCH_CONFIG_DISABLE_MATCHERS` no longer exists.
+  * If you do not want to use Matchers in a TU, do not include their header.
+* `CATCH_CONFIG_ENABLE_CHRONO_STRINGMAKER` no longer exists.
+  * `StringMaker` specializations for `<chrono>` are always provided
+* Catch2's CMake now provides 2 targets, `Catch2` and `Catch2WithMain`.
+  * `Catch2` is the statically compiled implementation by itself
+  * `Catch2WithMain` also links in the default main
+* Catch2's pkg-config integration also provides 2 packages
+  * `catch2` is the statically compiled implementation by itself
+  * `catch2-with-main` also links in the default main

 Because Catch is implemented *entirely* in headers you might think that the whole of Catch must be compiled into every translation unit that uses it! Actually it's not quite as bad as that. Catch mitigates this situation by effectively maintaining the traditional separation between the implementation code and declarations. Internally the implementation code is protected by ```#ifdef```s and is conditionally compiled into only one translation unit. This translation unit is that one that ```#define```s ```CATCH_CONFIG_MAIN``` or ```CATCH_CONFIG_RUNNER```. Let's call this the main source file.

 Although this was a simple test it's been enough to demonstrate a few things about how Catch is used. Let's take a moment to consider those before we move on.
 
 1. All we did was ```#define``` one identifier and ```#include``` one header and we got everything - even an implementation of ```main()``` that will [respond to command line arguments](command-line.md#top). You can only use that ```#define``` in one implementation file, for (hopefully) obvious reasons. Once you have more than one file with unit tests in you'll just ```#include "catch.hpp"``` and go. Usually it's a good idea to have a dedicated implementation file that just has ```#define CATCH_CONFIG_MAIN``` and ```#include "catch.hpp"```. You can also provide your own implementation of main and drive Catch yourself (see [Supplying-your-own-main()](own-main.md#top)).
-2. We introduce test cases with the ```TEST_CASE``` macro. This macro takes one or two arguments - a free form test name and, optionally, one or more tags (for more see <a href="#test-cases-and-sections">Test cases and Sections</a>, ). The test name must be unique. You can run sets of tests by specifying a wildcarded test name or a tag expression. See the [command line docs](command-line.md#top) for more information on running tests.

 3. The name and tags arguments are just strings. We haven't had to declare a function or method - or explicitly register the test case anywhere. Behind the scenes a function with a generated name is defined for you, and automatically registered using static registry classes. By abstracting the function name away we can name our tests without the constraints of identifier names.
 4. We write our individual test assertions using the ```REQUIRE``` macro. Rather than a separate macro for each type of condition we express the condition naturally using C/C++ syntax. Behind the scenes a simple set of expression templates captures the left-hand-side and right-hand-side of the expression so we can display the values in our test report. As we'll see later there _are_ other assertion macros - but because of this technique the number of them is drastically reduced.
