!!! Upgrade Notes and Prerequisites

* [https://github.com/TASEmulators/BizHawk#installing|The readme] on GitHub has more instructions, and is usually more up-to-date than this page.
* Never mix different versions of BizHawk. Keep each version in its own folder.
* __Windows users__: Don't forget to run the [https://github.com/TASEmulators/BizHawk-Prereqs/releases|prereq installer] first!
** Due to how BizHawk has evolved, earlier releases (1.x and 2.x before 2.4) might not work unless you also run an older version of the prereq installer.
** BizHawk versions starting from 2.0 require a 64-bit OS. A "backport" release, [Bizhawk/ReleaseHistory#Bizhawk1132|1.13.2], is available for users of Windows XP, 7, or 8.1 32-bit.
* __Linux users__: Distro-specific build instructions / packages are linked from [https://github.com/TASEmulators/BizHawk#unix|the readme]. A list of known bugs affecting the latest release can be found in [https://github.com/TASEmulators/BizHawk/issues/1430|issue #1430].

* [https://github.com/TASEmulators/BizHawk/releases/download/2.4.1/BizHawk-2.4.1.zip|Windows binary]
* Released May 2, 2020
* Installation notes
** Upgraded to .net 4.8, and c++ runtime deps have changed
*** Run the new prereqs installer
** config.ini files from previous versions will no longer work

* New Core!
** SubGBHawk - similar to SubNesHawk, allows for sub-frame movie recording support

* mGBA
** update mgba to 0.8.1
** Add memory callback support (debugger and lua)
** Add trace logging support
** Add input callback support
** Support cpu register setting

* Gambatte
** Many updates ported from upstream Gambatte through Gambatte-Speedrun to support the following:
*** Console accuracy for Pokemon TCG 1 and 2, now matching Game Boy Player when played as GBCinGBA mode
*** GBP console accuracy for Mickey's Dangerous Chase and other plain GB games that use LCDC interrupts when played as GBCinGBA mode
*** Maintain sync for all existing GBP console verified TASes 
*** Pokemon Crystal (JP)
** Ignore GBCinGBA setting unless console mode is GBC.  GBCinGBA mode causes an edit to the GBC BIOS so that it matches GBA/GBP/GBI timings.  If in GB mode this option is irrelevant.
** A new palette mapping option "Libretro".  The shader is an option in Extrems' GBI and in RetroArch.  It accounts for non-linear colorspaces while doing the color mixing documented in Gambatte and in Libretro's shaders for the GBC LCD.  See [Forum/Posts/494017|this thread] for visual comparisons.
