This is the an interim release of Sugar 0.88 + GNOME series for XO-1. Please refer to this page for the current status and download instructions:
http://wiki.sugarlabs.org/go/Deployment_Team/Sugar-0.88
With this build, all the major regression relative to 0.84 are fixed. The switch to Metacity resulted in a few hard issues on Fedora 11. There are still several smaller bugs to work on.
All the new features planned for this cycle are now merged, with the notable exception of collections support for the activity updater, which urgently needs a volunteer. At this point, it seems too late for the much anticipated resurrection of Rainbow. Maybe next time.
There may still be time to merge and stabilize a couple of minor features, such as a button in the Network control panel to re-register with the schoolserver.
== Changes relative to the previous release (os258py) ==
* Integrate journal backup and restore to USB (esteban, tch)
* Integrate function for mounting a GNOME Documents folder in the journal. Still presents some rough edges. (jasg)
* Pull latest OS updates from upstream (fedora)
== Bugs fixed in this release ==
* Make ALT-TAB work. It was caused by a bug with XUngrabKey() in the old Xorg server of Fedora 11, but we worked it around in Metacity. We spent a lot of time to figure it out! (tch, bernie)
* Fix windows staying in frame after startup. It turned out to be a libwnck bug, solved by upgrading it to a more recent version (aa, bernie)
* Fix fonts too big in all activities. This was a fallout of us temporarily disabling sugar-settings-manager, due to another bug (jasg).
* CTRL-C/CTRL-V don't work in Turtle Blocks (walter)
* Sugar sometimes restart. My fault: I included in the build an experimental Geode driver to check if it would now be safe to re-enable some EXA acceleration. It wasn't. (bernie).
== Known bugs ==
We still have a bunch of less serious issues requiring attention:
* Activity updater needs to support microformat and collections
* Sometimes pulsing launch icon is delayed or absent (scheduling issue? Sometimes I can see Sugar eating up 50% of the CPU when starting an activity)
* Font in Write is small and text does not fill the screen width. Sugar 0.82 and 0.84 used "Dejavu Sans", 0.88 uses "Times New Roman", which is smaller. (someone take it? pretty please?)
* Disconnects from network on power save. This is a long-standing kernel bug. In 0.84, we "fixed" it by disabling power management.
* Social Calc contains a race condition that makes it fail to start. Frankly, I would just ditch it, but teachers seem to like it very much
* More GNOME lock-down. See the thread with subject "GNOME and protecting Sugar" on sugar-devel@.
Thanks to anyone who could help us fixing these problems.

Excellent integration work! Before, it used to be the upstream developers who had to also debug on Fedora and sometimes on other distros, and as you said, it often takes a lot of time.
It's great that this work has moved downstream!

If you can reproduce it, it would be great to gather some profile data during activity launch with this:
## Before launching ## profiler = cProfile.Profile() profiler.enable()
## After launch ## profiler.disable() profiler.dump_stats('/tmp/profile')
It should tell what's Sugar up to.
Cheers,
Tomeu
