There really isn't a good reason to post the whole "Changelog" here as the plugin has been completely remade from the ground up (Since 1.6.2)
https://github.com/BeepSterr/BetterKeepInventory/releases/tag/v2.0.0

If you've been running the beta versions, here is what has changed since BETA-3

• Fixed the Version Checker prioritizing BETA over STABLE releases.
• Fixed an issue where PERCENTAGE_REMAINING in the damage effect did not behave as expected
• Added support for folia server
