Jammarr 1.0.1

Fixes

• Fixed Forge 1.7.10 clients crashing with LWJGL2/OpenAL native-link errors when Forge performs overlapping sound-engine reloads.
• The normal 1.7.10 startup now lets the initial sound loader settle, recovers safely from unusable or reloaded sound engines, and restores vanilla music when Jammarr releases playback.
• Replaced fragile modern SoundManager/SoundEngine accessor Mixins with runtime type-based field lookup, fixing Forge and NeoForge audio startup in production mappings.
• Hardened Minecraft 26.x Fabric/Quilt Mixin metadata generation and verification.

There is no protocol or configuration migration. Jammarr remains on protocol 5 and retains the complete 16-artifact / 21-runtime compatibility matrix.

Validation

GitHub Actions validated all 16 build targets and the complete 21-runtime matrix, including Quilt, Quilt with Mod Menu, the minimum supported Fabric Loader, dedicated-server configuration rejection, two-client synchronized playback, audible program capture, and clean shutdown. See the successful 1.0.1 release gate for commit 1825f8189bcb0cf529f1ce5d4e11e5031192613c.

Installation

Install exactly one JAR matching the Minecraft version and loader on both the dedicated server and every client. Quilt uses the matching -fabric.jar; there is no separate Quilt download.

See the compatibility matrix and migration guide for details.
