It seems it also brought player level maps and various player level scripting improvements as done
for the 3DS version - and it introduced Gamepad support!

Type: Major Update

Hey everyone! I am super proud to announce VVVVVV 2.3, the first major update to the game in seven years!

(Adorable fan art by Cheep! See attatched image VVVVVV_fan_art.png!)

This release was made possible as a direct result of making the game's source code available last year,
and accepting contributions from the community. It's the result of nearly 2000 commits to the codebase,
fixing hundreds of small bugs and making the game run at its best on modern computers.
A really big thanks to all of our contributors for helping to make this happen - especially Ethan Lee and
especially especially InfoTeddy, who contributed the vast majority of the fixes to this version.

I'll link the complete changelog below, but the highlights are:
   o 60+ FPS support
   o Improved graphical options
   o New features in the editor
   o Hundreds of bug fixes

For the complete change log, see here! Enjoy the update!

On GOG Offline Installer (03.|10.|14.09.2021):
   o Lin:   2.2 => 2.3.1 (49714) => 2.3.3 (49841) => 2.3.4 (49985)

# JMB: Note that before 2.3 there were 32 bit and 64 bit binaries, while now it is pure 64 bit.
#          This should be OK - it is 2021+ - and if so desired source code is there and can be compiled for ancient HW!

   o Removed a trailing space at the end of the "Press to Teleport" dialog

2.3.6

Looks like a patch that was backported wasn't the whole patch ...
so one last thing before the holiday panic starts!

   o Fix a regression from the hardreset fix in 2.3.5
   o Add some error checking to the image loader
