HuskTowns 1.5.6 is a minor update that moves data operations over to the more efficient Hikari connection pooling (hence the slightly larger file size) and fixes a few bugs.

• HuskTowns now uses Hikari connection pooling for establishing a connection to your database
  • Added new connection_pool_options section in the config file letting you control the pool size
• Adjusted the initialization order of LuckPerms data to prevent a crash when loading lots of data
• Fixed an issue where the initial data load could get stuck in some instances causing a softlock that required a manual reload
• Corrected some outdated links in the plugin info menu
• Fixed a few issues with the update checker and servers running offline
• A town's farewell message will no longer display while you are auto claiming to reduce chat spam
• Fixed caches incorrectly reporting the time it took for reloads after the initial one to process
• Minor code optimizations and tweaks

To update, you can drag+drop the previous jar. The only config changes are the additions of Hikari connection pooling options.
