v2.4.0

• Massive performance improvements (10-40%!)
• CPU and memory timings have been corrected* (passes Blargg's tests!)
• If you're making a plugin, then note that post_tick is now only called once at the end of pyboy.tick. Not for every frame.
• Clarify in docs that reads from pyboy.memory might return a memoryview in the future.
• If you're running pytest locally, TEST_CI has been removed and you now have to specifically set TEST_VERBOSE_IMAGES=1 to see debug images.

*If you depend on exact timing of a frame (assume a specific start block in Tetris etc.) then expect these to have changed. This change improves emulation correctness, and I cannot promise specific frame timings between releases.

v2.0.0

• A lot of general fixes

• pyboy.tick(10, True) now takes two optional parameters:
  • n number of frames to progress
  • render whether to render the screen on the last processed frame
• pyboy.screen_image() moved to pyboy.screen.image
• The "botsupport" module has been removed, and most of API is moved to the PyBoy object
• pyboy.button(‘a’) can be used to send input, and will automatically release after 1 frame
• pyboy.button_press(‘a’) allows for manual control of input
• pyboy.button_release(‘a’) allows for manual control of input
• pyboy.memory[0x100:0x150] = 123 replaces all three pyboy.get/set/override_memory_value and extends it with an option to specify bank
• pyboy.hook_register(bank, address, callback, context) registers a callback at a specific point in your game. Used for fine-grained tracking of events and control of the game
• pyboy.symbol_lookup(symbol) to look up address for a symbol to use with memory read/write
• “dummy” and “headless” windows have been merged into “null” window because of the new pyboy.tick
• pyboy.game_wrapper Game wrappers are now automatically loaded and accessible through the game_wrapper property

• OpenAI Gym/Gymnasium has been removed from PyBoy. It will be replaced by an example on the Wiki instead
• pyboy.memory_scanner allows to isolate memory address of interest
• Support for 768 CGB tiles vs. 384 in DMG mode
