The links to documentation do not work - this is the most severe problem, and probably stops people permanently changing to the new version.



The Haddock documentation is not present.



Some database entries are duplicates.



The Lambdabot says feature is missing.



The Suggestion feature is incomplete.



The AJAX style client features are not present.



Since releasing a command line version of Hoogle 4 yesterday, I've had some useful feedback from a number of people. As a result, I have added a few bugs to the bug tracker , and fixed a few mistakes in the searching and ranking. The Hoogle on Hackage is currently 4.0.0.3 and is a recommended upgrade to all early testers.I've now written a web interface to Hoogle 4, which has been uploaded to http://haskell.org/hoogle/beta/ . This web interface is primarily so people can test searching/ranking without installing anything. There are a number of limitations:The first three issues are fixed in Hoogle, but need various support through Haddock and Cabal to work. Other than these limitations, I am very interested in hearing what people think. As before, particularly regressions from Hoogle 3 or poor results/ranking.
