Not much has been changed, I just figured Early Access 1.5 would make more sense than Early Access 1.4.2, which is a perfect transition into the next big item: Early Access, I'm not currently aware of when it's happening but I'm submitting it for review right after this announcement is published.
On another note, changes in 1.5:
- Changed the dimensions of the camera
- Added death messages and revamped the death screen
