===============
Version 0.15.90
===============

* RetroMainLoop:
 - Lower the priority of the loop to prevent a lagging game from
   freezing the rendering of its video.
 - Prevent reference leaking when destroying the loop while its not
   stopped by not giving a reference to the loop's callback.
* RetroGLDisplay:
 - Take the UI's scale into account, making it usable in Hi-DPI.
* Prepare RetroGLDisplay for GTK+ 4:
 - Don't clear depth buffer as we don't use it and as this would cause
   glitches in GTK+ 4.
 - Explicitly use glClearColor().
 - Call glBindTexture() on every frame to ensure that we're always
   working with the right texture, which is needed for GTK+ 4.
* Fix reference cycles in retro-demo to avoid memory leaks.

Version 0.15.3
==============

* Add the RetroOption, RetroOptionIterator and RetroKeyJoypadMapping
  types to the public API.
* RetroCore:
 - Add the 'runahead' property. This allow the core to output the video
   and audio of a future frame, allowing to compensate for input lag
   from the original hardware for console emulator cores.
 - Add the retro_core_has_option(), retro_core_get_option() and
   retro_core_iterate_options() option accessors.
 - Add the 'options-set' signal. The signal is emitted when the core
   initially sets the options during boot. This allows setting options
   that require being set before the core is initialized.
* RetroCoreView:
 - Use a RetroKeyJoypadMapping to let users set its keyboard to virtual
   joypad mapping.
 - Set default controllers only for actually supported capabilities.
* Make RetroCoreViewController return only the capability matching its
  type and not all the the capabilities of its RetroCoreView.
* Add retro_joypad_id_to_button_code() and
  retro_joypad_id_from_button_code() to convert a Linux button event
  code into a RetroJoypadId and vice versa.
* Add RETRO_RUMBLE_EFFECT_COUNT, allowing to know the number of values
  of RetrormbleEffect.
* Libretro environment commands:
 - Implement RETRO_ENVIRONMENT_SET_GEOMETRY, allowing cores to change
   the aspect ratio separately from the framerate.
 - Implement RETRO_ENVIRONMENT_GET_LANGUAGE, allowing cores to know the
   user's language.
 - Fix a missing return in the implementation of
   RETRO_ENVIRONMENT_SET_DISK_CONTROL_INTERFACE, which could have led
   the cores to think we don't support it.
* Fix various runtime warnings and potential crashes.
* Improve internal documentation on keyboard key convertion.
* Add UNIMPLEMENTED.md as documentation of what is unimplemented from
  the Libretro API, updated to retroarch 1.7.2.
* Add the retro-reftest program allowing to easily run reference tests
  on Libretro cores, based on retro-gtk and test descriptor files.
 - It allows to generate the test references via the --generate option.
 - It allows to control the core by setting controllers and their
   inputs.
 - It can check that a core boots.
 - It can check that it has the expected options.
 - It can check that its internal state can or can't be accessed.
 - It can check that a frame runs.
 - It can check that the video output is as expected
* Add the retro-dummy dummy Libretro core, used to run unit tests and
  reference tests.
* Add some RetroCore unit tests.
* Let retro-demo take parameters for medias to load into the core.
* Add the following options to Meson:
 - 'introspection' to disable compilation of instrospection.
 - 'demos' to disable compilation of demos.
 - 'build-tests' to disable compilation of tests.
 - 'install-tests' to enable installation of tests.
