13.6.2

- SDL renderers were ignoring tiles where only the background red channel was changed.

13.6.1

- The SDL2 renderer has had a major performance update when compiled with SDL 2.0.18.
- SDL2 is now the default renderer to avoid rare issues with the OpenGL 2 renderer.

13.6.0

- `BasicMixer` and `Channel` classes added to `tcod.sdl.audio`.  These handle simple audio mixing.
- `AudioDevice.convert` added to handle simple conversions to the active devices format.
- `tcod.sdl.audio.convert_audio` added to handle any other conversions needed.

13.5.0

- `tcod.sdl.audio`, a new module exposing SDL audio devices.  This does not include an audio mixer yet.
- `tcod.sdl.mouse`, for SDL mouse and cursor handing.
- `Context.sdl_atlas`, which provides the relevant `SDLTilesetAtlas` when one is being used by the context.
- Several missing features were added to `tcod.sdl.render`.
- `Window.mouse_rect` added to SDL windows to set the mouse confinement area.
- `Texture.access` and `Texture.blend_mode` properties now return enum instances.
  You can still set `blend_mode` with `int` but Mypy will complain.

13.4.0

- Adds `sdl_window` and `sdl_renderer` to tcod contexts.
- Adds `tcod.event.add_watch` and `tcod.event.remove_watch` to handle SDL events via callback.
- Adds the `tcod.sdl.video` module to handle SDL windows.
- Adds the `tcod.sdl.render` module to handle SDL renderers.
- Adds the `tcod.render` module which gives more control over the rendering of consoles and tilesets.
- Fixed handling of non-Path PathLike parameters and filepath encodings.

13.3.0

- New experimental renderer `tcod.context.RENDERER_XTERM`.
- Using `libtcod 1.20.1`.
- Functions accepting `Path`-like parameters now accept the more correct `os.PathLike` type.
- BDF files with blank lines no longer fail to load with an "Unknown keyword" error.

13.2.0

Added
 - New `console` parameter in `tcod.context.new` which sets parameters from an existing Console.

Changed
 - Using `libtcod 1.20.0`.

Fixed
 - Fixed segfault when an OpenGL2 context fails to load.
 - Gaussian number generation no longer affects the results of unrelated RNG's.
 - Gaussian number generation is now reentrant and thread-safe.
 - Fixed potential crash in PNG image loading.

13.1.0

Added
 - Added the `tcod.tileset.procedural_block_elements` function.
Removed
 - Python 3.6 is no longer supported.

13.0.0

Changed
 - Console print and drawing functions now always use absolute coordinates for negative numbers.

12.7.3

Deprecated
 - `tcod.console_is_key_pressed` was replaced with `tcod.event.get_keyboard_state`.
 - `tcod.console_from_file` is deprecated.
 - The `.asc` and `.apf` formats are no longer actively supported.

Fixed
 - Fixed the parsing of SDL 2.0.16 headers.
