A bunch of exciting things have happened to Konqueror in preparation for 4.1 Beta 1 this weekend.
First of all, KHTML guru Germain Garand has committed the bulk of the designMode/contentEditable editing code. It's not 100% done yet, but it's a monumental amount of work, and it should enable the various rich-text editor apps to work in KHTML.
In the UI land, Eduardo Elvira has committed some fancy session management features such as crash recovery.
But, I am gonna be bit a bit selfish, and mostly talk about what I did: my performance/bytecode version of KJS - KJS "Frostbyte" - is now in kdelibs trunk, and part of KDE4.1 Beta 1. This brings some significant pure ES performance improvements over previous versions, and lets us put up some great numbers. On the SunSpider benchmark suite, this version does:
- 2.27x better than Firefox 2
- 2x better than QtWebKit from Qt4.4
- About 1.4x faster than KJS 4.0 "Blizzard"
- About 1.152x faster overall than Opera 9.5 beta 2, but it's really a wash, with both engines winning lots of individual benchmarks...
.. but about 1.77x slower than Firefox 3rc1. Ouch. Well, at least we beat them on Acid3, and it might just keep my head from getting too big. Great job by the Mozilla guys there, though. And the Apple guys of course aren't standing still either --- the development versions of JavaScriptCore/Safari have excellent optimizations we lack, and will likely be getting their own bytecode engine, SquirrelFish, soon (I name things after weather. They name them after weird animals. I think you can see who lives in California, and who lives in New York State).
Thankfully, I have some tricks left up my sleeve. Which isn't very comfortable, since I am wearing a t-shirt.
And if you care, or are really bored, the numbers are under the cut.

wow
wow re performance and wow^n re Acid3. You guys are amazing
Impressed
Great stuff. Once again goes to show that the KHTML team is one of KDE's crown jewels, doing world-class work.
Excellent
Really I want to test Konq. 4.1 as soon as I can. Specially to test WYSITWG editors !!

Cool!
*recompiling everything now*
Wow!
Very nice work guys!
google-friendly?
Will konqueror 4.1 be able to manage google-notebook?
