ResourceLoader

Resourceloader 2.5.1

Fixes

- Players are no longer kicked for declining or failing an optional pack. With enforcement off (the default), declining a pack sent by /load, or failing to download it, kicked the player, and operators with resourceloader.bypass were kicked as well. Kicks now only happen when enforcement.enabled is on, and only for the pack enforced on join. A pack a player picks later can be declined freely. - Packs copied into the `packs` folder while the server was off are now detected on startup and on /resourcereload. Before, only packs added while the server was running got registered. Files that aren't valid zips are skipped with a warning. Custom storage.resource-pack-directory folders are now watched too. - Merged packs work on 1.21.9+ and 26.x. /mergepack never actually saved the updated pack.mcmeta into the zip, and its version table stopped at 1.21, so 26.x clients saw merged packs as incompatible. Merged packs now declare a format range covering every input pack and the server's own version, in the layout newer clients require (min_format/max_format, plus supported_formats for older ones). - Merge priority with 3+ packs: a file from a middle pack could be overridden by the first pack. Later packs now always win. - Merging no longer drops content from lower packs: language strings, texture atlas sources and sounds.json entries are combined the way the game combines stacked packs. Models are no longer broken by gluing together elements from different packs. - `/autoload` now works with URL packs (it used to do nothing), matches pack names case-insensitively, and players with bypass still get their own autoload pack on join. - Enforcement: the enforced pack is now sent as required. enforcement.restrict (blocking /tp, /home, /spawn… and interactions until the pack has loaded) now works. An autoload preference pointing at a removed pack no longer lets a player skip the enforced pack. - URL packs: if the pack's host is down, the cached copy is used instead of failing. Unchanged packs are no longer re-downloaded after a restart. An interrupted download no longer leaves a broken cached file. cache.enabled: false no longer breaks URL packs. - `enforcement.use-server-properties`: /autoload preferences now apply on join, and a preferred pack is added on top of the server.properties pack instead of replacing it. - `/checkpack`: accepts 1.21.9+/26.x packs that use min_format/max_format, flags the same pack.mcmeta mistakes the game refuses to load, warns when a pack's version doesn't match the server, stops reporting vanilla textures as missing, and no longer shows "successful" next to critical issues. - Merge GUI: selected packs now show "✓ Selected", and clicking items in your own inventory no longer triggers the Merge/Cancel buttons. - /mergepack output names are cleaned up, so a name can no longer write outside the packs folder. - A warning is logged at startup when server.address is empty and the detected address is a loopback or Docker one, the usual reason pack downloads fail on Docker/Pterodactyl hosts. - Packs are no longer re-hashed on every send, which cuts join lag with large packs. - /load with a URL pack shows "Loading…" once instead of twice.

Resourceloader 2.5

Fixes

- Misplaced pack entries are repaired automatically (#11). Pack entries written at the top level of config.yml instead of under resource-packs: used to be silently ignored, so /load and /packlist showed nothing. They are now moved into resource-packs on startup and /resourcereload (a backup is saved as config.yml.pre-repair.bak) and the correct layout is explained in the log. - Warns when enforcement is enabled but server-pack is empty. - Missing-pack warnings now show the full path the file was expected at. - /load matches pack names case-insensitively. - /removepack no longer errors when resource-packs is missing. - /checkpack honours a custom storage.resource-pack-directory. - Fixed messages with more than one placeholder being corrupted.

Translations

- New language option in config.yml: en, ru, tr, ko, zh (locale-style values like ru_RU or zh-CN also work). Translations are extracted to lang/messages_<code>.yml and fall back to English for any missing key. - All chat, help, version-check, /removepack, /checkpack and merge GUI text is now in messages.yml, so every message can be customised. - Added the missing kick.declined and enforcement.restricted-command message keys.

Added startup and reload config migration for bundled YAML files that preserves existing server values and creates backups. Improved custom pack directory handling, URL encoding, async pack hashing, resource-pack server safety, and enforcement config key usage.

Monitoring and Statistics

- Added pack usage tracking and performance metrics - Implemented player preference history with configurable limits - Enhanced cache statistics and monitoring capabilities - Improved validation result reporting with formatted output

Security and Stability

- Added input sanitization for pack names and file paths - Enhanced permission validation throughout command execution - Implemented safer file operations with atomic writes where possible - Improved configuration protection against corruption

- Fixed /autoload - Added functionality for utilizing server.properties to load resource pack before player joins - Added customizable resource pack folder path - Allowed auto-detection to be toggle-able - Fixed bugs in messages - Added new messages.yml - Made resource pack merging more efficient and space conscious - Made resource pack loading smoother and more dynamic

For Server Admins

New configuration options in config.yml:

enforcement:
  enabled: false      # Turn on/off required resource packs
  action: kick        # What happens when players decline (kick or restrict)
  decline-message: "You must accept the resource pack!"

cache:
  enabled: true       # Turn on/off pack caching
  days: 7            # How long to keep cached packs
  auto-cleanup: true  # Automatically remove old cache

/mergepack added

Users can now merge multiple resource packs on their server into a single pack right in their server itself!

Rewrote the entire file path support.

The webserver that's created for hosting the resource pack files locally is now more secure and optimized.

Added a version checking command

/resourceversion (/rv) now tells you the version of Resourceloader you're running.

Added file path support

Resource packs can now be locally hosted on the server and be referenced through file path.

Added /autoload

Players can now automatically set a preferred resource pack to load when they join the server using /autoload
