The Invincibility Patch (21 April 2016)

Added frames of invincibility to dash
Warp pads now refill health kits
Achievements for Dash challenge + Soccer
for KB+M: can now choose option for KB direction dash
Sped up heal several frames
Adjusted various room scenery/hitches across the world
Fixed Alt Drifter dash catch
Fixed a credits crash
Can now go to full credits again after you beat the game through “credits” menu option
Health kits no longer recharge at warp pads
Reduced number of invincibility frames in the dash
Extended heal time slightly

Err... I'm sorry, am I missing something or does those two changes contradict each other?

Indeed. I just copy-pasted the official changelog on the game's GOG shelf. Another contradiction is "Warp pads now refill health kits" vs. "Health kits no longer recharge at warp pads"...

The bit about healing being sped up is also cancelled out; I'm pretty sure those entries are meant to be a joke.

Changelog for Patch 24 June 2016:

- fixes a few more bugs with coop and other random problems users have reported
- adds language support for Spanish, German, Japanese, Italian, Russian and French

Can someone (staff? idk) please edit my review to mention this update? It's still the top review and after adding 60fps it's now giving false information.

May we know when will this patch deployed also for the linux version?
Thanks!
