# Deprecations and incoming changes
This page documents current deprecations and upcoming planned changes
inside Catch2. The difference between these is that a deprecated feature
will be removed, while a planned change to a feature means that the
feature will behave differently, but will still be present. Obviously,
either of these is a breaking change, and thus will not happen until
at least the next major release.

## Deprecations
2018-11-17 11:01:29 +01:00
### SourceLineInfo::empty()
There should be no reason to ever have an empty `SourceLineInfo`, so the
method will be removed.

## Planned changes
2018-11-17 21:13:56 +01:00
### `CHECKED_IF` and `CHECKED_ELSE`
To make the `CHECKED_IF` and `CHECKED_ELSE` macros more useful, they will
be marked as "OK to fail" (`Catch::ResultDisposition::SuppressFail` flag
will be added), which means that their failure will not fail the test,
making the `else` actually useful.
### Console Colour API
The API for Catch2's console colour will be changed to take an extra
argument, the stream to which the colour code should be applied.
