1.12.3-legacy MC 1.9.4 → 1.21.10 maintenance build
First release of the legacy support branch. Drop-in replacement for older TimeManager builds — keeps every existing feature and behaviour, restores compatibility with MC versions that the 1.21.11+ master no longer targets.

COMPATIBILITY

• Minecraft: 1.9.4 → 1.21.10
• Java: 8+ (jar is Java 8 bytecode, runs on every Java 8/11/16/17/21 JVM)
• Server: Bukkit / Spigot / Paper

WHAT'S IN THIS RELEASE
Eight legacy-support fixes + one admin-alias improvement. Boot-tested on Paper 1.9.4 + Paper 1.16.5; modern paths unchanged (still gated by the existing reqMcVFor* flags).

BUILD

• chore(build) Java 8 compiler target so legacy JVMs can load the jar

CROSS-VERSION FIXES

• fix(plugin.yml) drop api-version to '1.13' so the jar loads on every supported MC version
• fix(config-files) guard parseComments() + setHeader() (1.19+ API) in CfgFileHandler / CmdsFileHandler / LgFileHandler
• fix(version-parser) handle empty + non-numeric version strings safely
• fix(now-item) skip NowItemHandler registration on pre-1.13 (relies on NamespacedKey + PersistentDataContainer)
• fix(daylight) bridge GameRule.DO_DAYLIGHT_CYCLE to legacy setGameRuleValue(String, String) on pre-1.13
• fix(title) fall back to 2-arg sendTitle(String, String) on pre-1.11
• fix(actionbar-hud) wrap broadcast in try/catch so silent failures surface in the log

ADMIN ALIAS

• feat(/time) forward set / add / query arguments to vanilla minecraft:time so the classic admin syntax keeps working alongside TM's /now display

NOTES

• No new features, no behaviour change on supported MC versions
• All fixes are defensive — gated by serverMcVersion checks, modern code paths are unaffected
• Tested servers: Paper 1.9.4-775 (Java 8) + Paper 1.16.5-794 (Java 8) → clean boot, /tm, /now, /time set <daypart>, /tm hud on all working

INSTALL

1. Drop TimeManager-1.12.3.jar into plugins/
2. Restart the server (or /reload confirm)
3. Config files at plugins/TimeManager/ are unchanged on first run
