XPages Jakarta EE support libraries
Version 3.0 brings a move to Jakarta EE 10, which also means a requirement bump to Domino 14 or above. Additionally, the libraries are now consolidated into three and some package names have changed, so NSFs will require some modifications to run with this version.
For an example of migrating existing NSFs, see this commit: https://github.com/OpenNTF/org.openntf.xsp.jakartaee/commit/3d9c23fa5861274ce5f6540700d2ff2d6cedf362
