* Add sdvxio-kfca driver to talk to real SDVX hardware
* Refactor d3d9 hook module to improve maintainability. Also fixes upscaling not working on IIDX20+.
* Remove d3d8 hook module to improve maintainability. Make old d3d8 based games, e.g. iidxhook1/2, use d3d9 instead.
Requires usage of d3d8to9 wrapper library to use gfx patching features.
* Add dev doc about IIDX rendering loops
* Add an initial draft of an architecture document (will be worked on in iterations)
* Refactor BIO2 emulation to make it re-usable by other games

## 5.26
* iidxio-ezusb: Reduce sleep time to Sleep(1) to avoid framerate issues on some versions of iidx.
* Bugfix: iidx d3d9 games, mainly the newer ones iidx 20-25, freezing. Happened on boot, during song selection or during the song.
* Bugfix: log_server_init deadlock on iidxhook4-7. This caused games like iidx24 to hang before even showing a render window.
* iidxhook: Add feature to allow GPU based up-/downscaling of rendered frame. This gives
you the possibility to upscale the resolution of old SD (640x480) games to your monitor's/TV's
native resolution which can have a few advantages: better image quality if the monitor's upscaler
is not doing a good job, especially on resolutions that are not a multiple of its native resolution;
Reduce display latency if the upscaler is slow, avoid over-/underscan which cannot always be fixed
entirely or at all (depending on your GPU and monitor model). See the iidxhook configuration file
for the new parameters available.
* Major readme cleanup. Add development documentation like style guide, guidelines, development setup.

## 5.25
* Bugfix: iidx14 and 15 crashing on Windows 10
* Bugfix: IO2 driver not using correct package sizes on reads/write -> iidxio-ezusb2.dll now working
* Improve ezusb2-boot.bat script to handle flashing of IO2 firmware
* Remove broken x64 builds of ezusb1/2 tools -> Just use the x86 tool versions instead
(use the x64 versions of iidxio-ezusb.dll and iidxio-ezusb2.dll with iidx25)
* iidxhook1-8: Allow floating point values for frame rate limiting, e.g. 59.95 (hz).
* Improve timing with ezusb (C02) driver

## v5.24
* Bugfix: iidxhook8 hangs very early on startup (race condition in log-server module)

## v5.23
* Refactored configurion (file) handling for iidxhooks, RE-READ THE DOCUMENTATION.
This gets rid of the "short cmd parameters", e.g. -w for windowed mode, and replaces
them with full name parameters, e.g. -p gfx.windowed=true, which improves handling
of configuration files/values. 
* Add a lot of unit tests to the codebase
* Refactored round plug security infrastructure, shared with IIDX and jubeat (1)
* Move shared utility modules between iidxhook modules to a separate utilty module 'iidxhook-util'
* Add experimental jubeat (1) support (buggy IO emulation) 
* Various fixes to improve all iidxhooks when running on Windows 10
* Bugfix: iidxio-ezusb getting stuck on newer Windows platforms
* Update iidxhook docs, e.g. how to get old IIDX versions sync on Windows 10
* Various documentation updates
* Various code cleanup
* Various other minor bugfixes

## v5.22
* Added a lot of documentation and readme stuff (READ IT!!11)
* Re-numbering iidxhook implementations to make room for missing games
* Support for IIDX 18 -> iidxhook4
* Support for IIDX 19 -> iidxhook5
* Support for IIDX 20 -> iidxhook6
* A lot of code refactoring and cleanup
* Refactor p3io emulation
* Remove obsolete BT4 DDR stuff
* iidxhook: Refactored software monitor check and bugfixes. You can use the
auto monitor check to determine your machine's refresh rate or (new) set the
refresh rate yourself in the configuration file, e.g. when you already have
determined it using one of the newer IIDX games and want to skip that monitor
check or if BT5's software monitor check doesn't work properly (e.g. on Win 7).
* iidxhook1-3: Check if eamuse server is reachable and log a warning otherwise.
This should make debugging invalid URLs or connection issues easier.
* iidxhook: Revised ezusb and ezusb2 emulation layer. Translucent support
removed, all IO emulation goes through BT5's iidxio interface.
* iidxio: Add implementations for ezusb (C02 IO) and ezusb2 (IO2) hardware. This
allows you to run _ANY_ IIDX game supported by BT5 either with real C02 or IO2
hardware.
* iidxhook: Remove translucent card reader feature. Again, to create a unified
interface for _ALL_ versions, use the eamio-icca.dll if you want to run on 
real ICCA (slotted or wavepass) readers. 
* Various other bugfixes

Again, read the various markdown (.md) readme files. We tried to document
everything to the best of our knowledge. If you are missing something, please
contribute by adding that information and submitting a patch to us.
