October 2026 Game Dev Calendar: Steam, Unity, Fab & Release Waves

Use this page as a traffic-and-production map rather than a generic news feed. Each date below connects a real October event or support deadline to a practical checklist, tool, asset route or seller workflow already on Knit of Shadows.

Through October

Unity 6.0 LTS support window closes

Unity lists Unity 6.0 LTS support through October 2026, while Unity 6.3 LTS is supported through December 2027. Teams still on 6.0 can use the month to test an upgrade copy, package compatibility and asset/build regression checks.

Halloween / jam production

Need a small-scope dark-fantasy route instead of a launch event?

The October Halloween page tracks asset-friendly game jams separately because jam rules differ. Re-check each live rules page before using AI-assisted or pre-existing assets.
