(TLDR: Add docs page showing Unity / packages compatibility matrix) It would be great if Unity had a central docs page to streamline checking which packages / versions were compatible (or otherwise) with other packages / versions. Also the currently recommended versions for each Unity version. Real-life example question: "Does the new Input System work with XR Interaction Toolkit?" [today's hard-to-find answer for hapless future searchers who end up here] Ideally I'd like to head to a landing page and quickly click through some sorted lists / smart menus (Unity version, 2 x package names): Unity 2019.4.1f1 > Input System > XR Interaction Toolkit then see a table of package versions (Input System rows, XR Interaction Toolkit columns) with entries in the table indicating "recommended for new projects", "verified", "preview" and "incompatible". At the moment I need to trawl through package docs (multiple versions), forum posts, blogs, videos, etc. Failing that, set up a test project and play import roulette in the package manager. Or worse, deal with mysterious project build errors if package dependencies don't catch incompatibilities. Helpful extra features to add: Each package version combination in the table has a count of open issues (stability indicator). The count links to the corresponding results page in the issues database. Each compatible version combo has a link that jumps to sample / test code, enabling quickstart best-practice coding. I'm guessing Unity has a package release process that can "help" package maintainers (firmly checkpoint?) keep their compatibility resources up to date.
