TRL 0.0.22 except for the v11 fix for embedded reactive collections. Outside of this one change there should be no other issues using TRL 0.0.23 on Foundry v10 & v11.4.3.8 as there are many improvements in the 4.3.x releases. Also, take note that if you update to a Svelte version 3.57.0 or greater there are new accessibility / a11y warnings depending on what you use in TRL / mainly the RTE editor components. I have already fixed that for TRL 0.0.24, but you will see new a11y warnings when building. This is not a problem and already fixed for the next official release.0.0.24 that moves things forward will be out in a couple off weeks. Just a heads up that the next release will have some API restructuring / not a change in functionality. This is a firm move toward "beta" and there will be some changes in where various API is imported from in the direction of more finite / exact sub-package exports. The good news is that rock solid TS declarations will be shipped with the upcoming release along with 100% cross-linked documentation making discoverability of aspects of TRL now possible. I'll mention more in the release notes for TRL 0.0.24.
