@ -32,7 +32,9 @@ This is the rolling changelog for TShock for Terraria. Use past tense when addin
* Added `summonboss` permission check for Prismatic Lacewing. Players who do not have said permission will be unable to kill this critter, as it will summon the Empress of Light. Also added support for the `AnonymousBossInvasions` config option, if this is set to `false` it will now broadcast the name of the player who summoned her. (@moisterrific)
* Added `ForceTime` config setting check for Enchanted Sundial usage. If `ForceTime` is set to anything other than `normal`, Sundial use will be rejected as this would lead to very janky game behavior. Additionally, players with `cfgreload` permission will be advised to change it back to `normal` in order to use sundial. (@moisterrific, @bartico6)
* Added `%onlineplayers%` and `%serverslots%` placeholders for MOTD. The default MOTD message was also updated to use this. (@moisterrific, @bartico6)
* Fixed a client crash exploit involving invalid tiles. (@Arthri)
* Fixed Bouncer exploits allowing for invalid tiles' placement. These tiles(specifically torches) caused clients to crash. The fixed exploits are listed below. (@Arthri)
- [Biome Torch Correction](https://github.com/Pryaxis/TShock/blob/3ba1e7419d63535eeb8b5634ec668448499f71df/TShockAPI/Bouncer.cs#L310). Previously, it used unrelated values to validate biome torches, and unintentionally passed on invalid tiles. It's now fixed to use the correct values and block invalid torches. As well as a new right booster track correction/check
- [Max Place Styles](https://github.com/Pryaxis/TShock/blob/3ba1e7419d63535eeb8b5634ec668448499f71df/TShockAPI/Bouncer.cs#L385). Previously, it fails only if both `MaxPlaceStyles` and `ExtraneousPlaceStyles` contains an entry for a tile, and unintentionally passed on invalid tiles. `ExtraneousPlaceStyles` only contains special max placeStyles, not all placeables unlike `MaxPlaceStyles`. It's now corrected to take from `ExtraneousPlaceStyles` first, then fallback to `MaxPlaceStyles` if there's no entry for that tile, and then finally -1 if there's no entry in either.
## TShock 4.5.4
* Fixed ridiculous typo in `GetDataHandlers` which caused TShock to read the wrong field in the packet for `usingBiomeTorches`. (@hakusaro, @Arthri)
