Project ships the code source as a Git tag git.eclipse.org/c/lsp4e/lsp4e.git/log/?h=0.8.0 , and the binaries as a p2 repository download.eclipse.org/lsp4e/releases/0.8.0 to use in the Eclipse IDE or in dependency manager.
Some changes in Language Server Protocol resulted in changes in LSP4J which cascaded to LSP4E.
While an exhaustive list of changes wasn't build, it's expected that anyone relying on LSP4E code should be careful about the migration as they may face API changes. But LSP4E currently publishes no API, so it's behaving well according to the contract. Compatiblity issues are the responsibility of consumers who use undeclared code as API.
LSP4E is internationalized.
LSP4E 0.8.0 is known to be compatible with Eclipse Platform 4.10. It may work with older releases although it's not tested.
