🚀 Final Push to the Finish Line: Recoil Engine 2025.06 Release

[lhog]

The 2025.06 release branch of Recoil Engine is hopefully entering its final stage. From here, the focus is on testing, fixing bugs, and getting everything ready to publish.

We’re aiming to wrap up validation soon so this release can go out smooth and stable. If you’re testing or reviewing changes, now’s the time to flag anything that still needs attention.

Thanks to everyone who’s been pushing this along - we’re almost there.

Recoil Engine Updates: 2025.06.19 → 2025.06.20

🐛 Bug Fixes

Fixed Linux exit crash - Moved minimap render buffers from CProjectile to CProjectileDrawer for proper cleanup before GL context destruction. This resolves crashes on exit that occurred on Linux systems.

ZipArchive safety improvement - Added error checking for unzGetCurrentFileInfo() to prevent crashes when processing malformed or corrupted zip archives.

Defensive dt handling in LuaUI - Added fallback to Spring.GetLastUpdateSeconds() when dt parameter is nil. Should address issues the games had when porting to 2025.06.19

Matrix tolerance adjustments - Increased tolerance thresholds in IsRotMatrix() and IsRotOrRotTranMatrix() from 8x/16x epsilon to 64x/128x epsilon to reduce false negatives in matrix validation checks. Only relevant in debug mode.

Headless fix - Added guard in CTextureRenderAtlas::CreateAtlasTexture() to skip OpenGL rendering operations when running in headless mode.

ArchiveScanner cache fix (ported from RecoilEngine) - Now properly clears brokenArchives and brokenArchivesIndex when reading cache to prevent stale data issues.

2025.06.21 will hopefully be the final release in the 2025.06 branch. I’ve already marked it as the next stable.

If any minor issues still show up, we’ll address them in the 2026.06 branch, which we’ve also decided to stabilize a bit earlier than usual.

Big congratulations to everyone involved - and especially to the engine dev team for all the work that went into this!
