+`ANON_TEST_CASE` is scheduled for removal, as it can be fully replaced
+by a `TEST_CASE` with no arguments.
+
+
+### Secondary description amongst tags
+
+Currently, the tags part of `TEST_CASE` (and others) macro can also
+contain text that is not part of tags. This text is then separated into
+a "description" of the test case, but the description is then never used
+apart from writing it out for `--list-tests -v high`.
+
+Because it isn't actually used nor documented, and brings complications
+to Catch2's internals, description support will be removed.
+
+### SourceLineInfo::empty()
+
+There should be no reason to ever have an empty `SourceLineInfo`, so the
+method will be removed.
+
+
+### Composing lvalues of already composed matchers
+
+Because a significant bug in this use case has persisted for 2+ years
+without a bug report, and to simplify the implementation, code that
+composes lvalues of composed matchers will not compile. That is,
+this code will no longer work:
+
+```cpp
+            auto m1 = Contains("string");
+            auto m2 = Contains("random");
+            auto composed1 = m1 || m2;
+            auto m3 = Contains("different");

+            REQUIRE_THAT(foo(), !composed1);
+            REQUIRE_THAT(foo(), composed2);
+```
+
+Instead you will have to write this:
+
+```cpp
+            auto m1 = Contains("string");
+            auto m2 = Contains("random");
+            auto m3 = Contains("different");

 ## Planned changes

+### Reporter verbosities
+
+The current implementation of verbosities, where the reporter is checked
+up-front whether it supports the requested verbosity, is fundamentally
+misguided and will be changed. The new implementation will no longer check
+whether the specified reporter supports the requested verbosity, instead
+it will be up to the reporters to deal with verbosities as they see fit
+(with an expectation that unsupported verbosities will be, at most,
+warnings, but not errors).

+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.
 
-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.
+## In use
 
+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.
 
-## Using Matchers
+For example, to assert that a string ends with a certain substring:
 
-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.
-
-For example, to assert that a string ends with the "as a service"
-substring, you can write the following assertion
-
-```cpp
-using Catch::Matchers::EndsWith;
-
-REQUIRE_THAT( getSomeString(), EndsWith("as a service") );
+ ```c++
+using Catch::Matchers::EndsWith; // or Catch::EndsWith
+std::string str = getStringFromSomewhere();
+REQUIRE_THAT( str, EndsWith( "as a service" ) );
 ```
 
-Individual matchers can also be combined using the C++ logical
-operators, that is `&&`, `||`, and `!`, like so:
+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:
 
-```cpp
-using Catch::Matchers::EndsWith;
-using Catch::Matchers::Contains;
+```c++
+REQUIRE_THAT( str, EndsWith( "as a service", Catch::CaseSensitive::No ) );
+ ```
 
-REQUIRE_THAT( getSomeString(),
-              EndsWith("as a service") && Contains("web scale"));
+And matchers can be combined:
+
+```c++
+REQUIRE_THAT( str,
+    EndsWith( "as a service" ) ||
+    (StartsWith( "Big data" ) && !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.
-
-
-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>`.
-
-**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):
+_The combining operators do not take ownership of the matcher objects.
+This means that if you store the combined object, you have to ensure that
+the matcher objects outlive its last use. What this means is that code
+like this leads to a use-after-free and (hopefully) a crash:_
 
 ```cpp

-

-    auto match_expression = Catch::Matchers::EndsWith( "as a service" ) ||
-        (Catch::Matchers::StartsWith( "Big data" ) && !Catch::Matchers::Contains( "web scale" ) );
+    auto match_expression = Catch::EndsWith( "as a service" ) ||
+        (Catch::StartsWith( "Big data" ) && !Catch::Contains( "web scale" ) );
     REQUIRE_THAT(str, match_expression);
 }
 ```
 
 
-## Built-in matchers
+## 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.
 
-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:
+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.
 
 
-### `std::string` matchers
+### 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.
 
-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`
+Each of the provided `std::string` matchers also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).

-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`.
 
-Catch2 provides 3 matchers that target floating point numbers. These
-are:
+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.
 
-* `WithinAbs(double target, double margin)`,
-* `WithinUlps(FloatingPoint target, uint64_t maxUlpDiff)`, and
-* `WithinRel(FloatingPoint target, FloatingPoint eps)`.
+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.
 
 > `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.
 
-`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:
-
+Because of type inference limitations, the argument type of the predicate
+has to be provided explicitly. Example:
 ```cpp
 REQUIRE_THAT("Hello olleH",
              Predicate<std::string>(
@@ -211,205 +123,84 @@ REQUIRE_THAT("Hello olleH",
 );
 ```
 
-> the predicate matcher lives in `catch2/matchers/catch_matchers_predicate.hpp`
+The second argument is an optional description of the predicate, and is
+used only during reporting of the result.
 
 
-The other miscellaneous matcher utility is exception matching.
+### 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 matched exception must publicly derive from `std::exception` and
+the message matching is done _exactly_, including case.
 
-#### 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`.
+> `ExceptionMessageMatcher` was introduced in Catch 2.10.0
 
 Example use:
 ```cpp
 REQUIRE_THROWS_MATCHES(throwsDerivedException(),  DerivedException,  Message("DerivedException::what"));
 ```
 
-Note that `DerivedException` in the example above has to derive from
-`std::exception` for the example to work.
+## Custom matchers
+It's easy to provide your own matchers to extend Catch or just to work with your own types.
 
-> the exception message matcher lives in `catch2/matchers/catch_matchers_exception.hpp`
+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.
 
-
-### 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>`:
+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):
 
 ```c++
-#include <catch2/catch_test_macros.hpp>
-#include <catch2/matchers/catch_matchers.h>
-// ...
-
-
-template <typename T>
-class IsBetweenMatcher : public Catch::Matchers::MatcherBase<T> {
-    T m_begin, m_end;
+// The matcher class
+class IntRange : public Catch::MatcherBase<int> {
+    int m_begin, m_end;
 public:
-    IsBetweenMatcher(T begin, T end) : m_begin(begin), m_end(end) {}
+    IntRange( int begin, int end ) : m_begin( begin ), m_end( end ) {}
 
-    bool match(T const& in) const override {
-        return in >= m_begin && in <= m_end;
+    // Performs the test for this matcher
+    bool match( int const& i ) const override {
+        return i >= m_begin && i <= m_end;
     }
 
-    std::string describe() const override {
+    // 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::ostringstream ss;
         ss << "is between " << m_begin << " and " << m_end;
         return ss.str();
     }
 };
 
-template <typename T>
-IsBetweenMatcher<T> IsBetween(T begin, T end) {
-    return { begin, end };
+// The builder function
+inline IntRange IsBetween( int begin, int end ) {
+    return IntRange( begin, end );
 }
 
 // ...
 
-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));
+// Usage
+TEST_CASE("Integers are within a range")
+{
+    CHECK_THAT( 3, IsBetween( 1, 10 ) );
+    CHECK_THAT( 100, IsBetween( 1, 10 ) );
 }
 ```
 
-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.
+Running this test gives the following in the console:
 
-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));
-}
 ```
-
-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.
-
-> `MatcherGenericBase` lives in `catch2/matchers/catch_matchers_templated.hpp`

-## 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 I intend to provide sqlite-style distribution option, with 1 header and 1 "unity" .cpp file. Do note that the header will have similar problem to 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.

-* 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.
-
-
-### 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
-

-## 2.12.1
-
-### Fixes
-* Vector matchers now support initializer list literals better
-
-### Improvements
-* Added support for `^` (bitwise xor) to `CHECK` and `REQUIRE`
-
-
-
-## 2.12.0
-
-### Improvements
-* Running tests in random order (`--order rand`) has been reworked significantly (#1908)
-  * Given same seed, all platforms now produce the same order
-  * Given same seed, the relative order of tests does not change if you select only a subset of them
-* Vector matchers support custom allocators (#1909)
-* `|` and `&` (bitwise or and bitwise and) are now supported in `CHECK` and `REQUIRE`
-  * The resulting type must be convertible to `bool`
-
-### Fixes
-* Fixed computation of benchmarking column widths in ConsoleReporter (#1885, #1886)
-* Suppressed clang-tidy's `cppcoreguidelines-pro-type-vararg` in assertions (#1901)
-  * It was a false positive trigered by the new warning support workaround
-* Fixed bug in test specification parser handling of OR'd patterns using escaping (#1905)
-
-### Miscellaneous
-* Worked around IBM XL's codegen bug (#1907)
-  * It would emit code for _destructors_ of temporaries in an unevaluated context
-* Improved detection of stdlib's support for `std::uncaught_exceptions` (#1911)

 All tag names beginning with non-alphanumeric characters are reserved by Catch. Catch defines a number of "special" tags, which have meaning to the test runner itself. These special tags all begin with a symbol character. Following is a list of currently defined special tags and their meanings.
 
-* `[.]` - causes test cases to be skipped from the default list (i.e. when no test cases have been explicitly selected through tag expressions or name wildcards). The hide tag is often combined with another, user, tag (for example `[.][integration]` - so all integration tests are excluded from the default run but can be run by passing `[integration]` on the command line).
