getfirebug.com has Firebug 1.5X.0a3. This is the first Firebug release that passes all of our “FBTests”, a collection of tests mostly inspired by user issues or new features. Last week, using 1.4a31, we passed all the tests running under Firefox 3.0.10; now we pass using the Firefox 3.5 nightly build, very close to the Firefox version that will be released as Firefox 3.5 Preview in the next 24 hours.
At this point can now turn the Firebug 1.4 branch over to Jan “Honza” Odvarko for the 1.4 beta releases. The rest of the development team will commit to branches/firebug1.5 and Honza will pick from the commits there to move the beta forward. This way Honza will be able to keep a steady improvement to the final release of 1.4.
We will try to bring out a 1.5a release ahead of every 1.4b release, both with similar code as a extra check to help the beta. So the content of 1.5a3 is a preview of the 1.4b release we hope to have tomorrow.
