Hello!
KrakatoaMX 2.10.3 has been released and is available on downloads.thinkboxsoftware.com.
Release notes are here Krakatoa MX Release Notes — KRAKATOA 2.10.x documentation
This release includes support for 3dsMax 2022 and ThinkingParticles 7.
It removes support for 3dsMax prior to 2019.
Note that there is currently an issue on the documentation page (https://docs.thinkboxsoftware.com/) where the product versions are not sorted properly (2.9 and 2.6 come before 2.10). We are working to correct that.
