New Features:

- The client can now ignore packet decoding errors when connecting to a server (fixes: #1 (comment 3011626189)) (introduced in v1.0.1-rc2)
- Automated release pipelines for GitHub and Modrinth have been set up (introduced in v1.0.1-rc2)
- The client now ignores packets larger than expected (fixes: #1 (comment 3067088739)) (introduced in v1.0.1-rc6)
- Client side packet handling errors are now ignored when connecting to a vanilla server, allowing the client to connect without issues. (fixes: : #1 (comment 3067399173)) (introduced in v1.0.1-rc7)
Bug Fixes and Changes:
- Patches are now disabled when connecting to NeoForge servers to prevent compatibility issues (introduced in v1.0.1-rc2)
- Fixed all occurrences of the typo "Quite" (should have been "Quiet") across the codebase (introduced in v1.0.1-rc2)
- Fixed a crash caused by invalid access transformer syntax despite Architectury Loom successfully applying the access transformer (fixes: #2) (introduced in v1.0.1-rc3)
- Fixed an issue where
isConnectedToVanillaServer
was not set early enough, causingCheckFeatureFlags.handleVanillaServerConnection
to behave incorrectly (fixes: #1 (comment 3065956489)) (introduced in v1.0.1-rc4) - Improved the implementation for ignoring packet decoding errors to be more robust (properly fixes: #1 (comment 3011626189)) (introduced in v1.0.1-rc5)
NetworkRegistryMixin
now checksClientConfig.bypassCustomFeatureFlags()
before callingCheckFeatureFlags.handleVanillaServerConnection
to ensure custom feature flags are ignored when connecting to servers that do not support them (fixes: #1 (comment 3066014192)) (introduced in v1.0.1-rc5)- Renamed
acceptVanillaServer
tobypassNegotiationErrors
to better reflect its purpose (introduced in v1.0.1-rc7)
