- the original project has been unmaintained for years - some dependants needed to be patched due to renamed headers https://github.com/htacg/tidy-html5/issues/326#issuecomment-160329114 - separate tidy-html5 package was removed, as since the 5.0.0 version it's meant as a successor to both, and library name got back from libtidy5.so to libtidy.so https://github.com/htacg/tidy-html5/issues/326#issuecomment-160314666 /cc committers to tidy-html5: @edwjto and @zimbatm.
