## Other notes
* The main test include is now `<catch2/catch_test_macros.hpp>`
* Big "subparts" like Matchers, or Generators, have their own folder, and
also their own "big header", so if you just want to include all matchers,
you can include `<catch2/matchers/catch_matchers_all.hpp>`,

## Things that can break during porting
* The namespace on Matchers were cleaned up, they are no longer first declared
deep within an internal namespace and then brought up. All Matchers now live
in `Catch::Matchers`.
* The reporter interfaces changed in a breaking manner. If you wrote custom
reporter or listener, you might need to modify them a bit.
* The namespaces of Matchers were flattened and cleaned up.
Matchers are no longer declared deep within an internal namespace and
then brought up into `Catch` namespace. All Matchers now live in the
`Catch::Matchers` namespace.
* The `Contains` string matcher was renamed to `ContainsSubstring`.
* The reporter interfaces changed in a breaking manner.
If you are using a custom reporter or listener, you will likely need to
modify them to conform to the new interfaces. Unlike before in v2,
the [interfaces](reporters.md#top) and the [events](reporter-events.md#top)
are now documented.
