Attending FOSDEM 2011

I'm going to FOSDEM, the Free and Open
Source Software Developers' European Meeting

Today Nick and I booked hotel rooms for FOSDEM so now it’s official that the two of us will be there. I’m very much looking forward to it and I’m hoping to meet some of you at the FOSDEM Beer Event on Friday! Still need to think about a way to make ourselves recognizable as Xfce folks though.

If you are planning to attend and would like to meet any of the Xfce folks, please add your name in the wiki:

  http://wiki.xfce.org/events/2011/fosdem

We haven’t decided where and when to meet on Saturday and Sunday but I’m sure we will find something. Stay tuned for additional announcements on this weblog.

In addition to celebrating the 4.8 release of Xfce which is scheduled for next weekend, one of our goals for FOSDEM 2011 will be to sign the papers for registering the Xfce Foundation e.V. in Germany. The details of this still need to be worked out, however. I’ll keep you posted about this as well.

If you would like to talk to me about things other than Xfce, please drop me a mail and I’m sure we can arrange something.

Today we are pleased to announce the third and hopefully final preview release of Xfce 4.8 which is set to be pushed out to the public on January 16th, 2011. Compared to Xfce 4.8pre2 this release mostly features translation updates and bug fixes.

With christmas and new year’s eve between 4.8pre2 and 4.8pre3 it comes as no surprise that for most components only a few issues were tackled.

Among other things we updated the default keyboard shortcuts to include monitor keys. The status icon of the file manager’s progress dialog is now properly hidden when the dialog is destroyed. It’s wallpaper plugin is now capable of handling filenames with spaces. The environment variables of commands launched from the Xfce run dialog were not set properly, so we fixed that so that commands launched from the dialog always inherit the environment of the Xfce session.

We also made the --reboot and --halt parameters of xfce4-session-logout work again which previously simply logged out the active user. In order to avoid a race condition at session startup and in order to speed things up a little more we no longer use xrdb to update xft and cursor settings and instead, update the related XSETTINGS properties ourselves.

In the window manager xfwm4, we aligned the time period required for a double click with that of normal applications. Via the hidden option “/general/mousewheel_rollup” one can now disable windows being rolled up via the mouse wheel. The window manager now also properly handles resolution changes in fullscreen windows like those appearing in games. Xfwm4’s application switcher now only appears once in cloned mode.

This may sound like a few useful fixes but it’s nothing compared to the amount of work that went into the new Xfce panel once again. Around 20+ known bugs and regressions were fixed. Here is a short excerpt of the complete changelog: Translation domains were fixed for external plugins, plugins can be reordered with DND again, double-clicking items in the item editor shows their preferences, dragging items to the item editor dialog removes them from the panel again, tasklist windows can now be filtered by monitor. Another issue that appeared recently and has now been fixed is the icon sizing in the notification area, also known as the systray.

Xfce 4.8pre3 also features a lot of translation updates, as can be seen in the complete changelog on

 http://xfce.org/documentation/changelogs/4.8pre3

Since we’re following the Xfce release model for 4.8, we’d normally announce code freeze and the creation of early lifecycle support branches today. We decided against this because there are not enough people active to take care of all this at the moment. So we will continue fixing bugs in master branches as we did between 4.8pre2 and 4.8pre3.

We’re hoping that you will enjoy today’s release. Thanks a lot to everyone contributing this time around! We’re pretty sure 4.8 is gonna rock.

Kind regards,

The Xfce development team

P.S.: Happy new year everyone!

Release notes for 4.8pre2

We are pleased to announce the second preview release of Xfce 4.8. This release marks the beginning of the string freeze. From today on until the final release, strings may no longer be changed in the master branch of Xfce core components. This will help translators to prepare their translations for the final release scheduled on January 16th, 2011.

For this release we focused on fixing bugs in all Xfce components. We managed to close a great number of them thanks to all the persons who reported them and tested proposed fixes quickly.

A few minor panel features were added despite feature freeze. We also managed to work on two long time requests: proper support for editing the application menu with menu editors (Alacarte being the one that we tested) and integration with the Compiz viewport. Of course, this release also features a lot of new and improved translations thanks to the amazing work of our translation teams.

A list of all changes is available on:

http://mocha.xfce.org/documentation/changelogs/4.8pre2

We hope you will enjoy this release. Please give us feedback by sharing your thoughts, blogging, tweeting, denting or by filing bug reports. With your help, 4.8 will be the best release ever (at least until 4.10)!

Kind regards and thanks to everyone who has contributed to this release,

Release notes for 4.8pre1

The Xfce development team is proud to announce the first preview release for Xfce 4.8. Together with this preview release, the Xfce project announces the feature freeze for the final 4.8 release which is set to be pushed out to the world on January 16th, 2011.

This release incorporates major changes to the core of the Xfce desktop environment and hopefully succeeds in fulfilling a number of long time requests. Among the most notable updates is that we have ported the entire Xfce core (Thunar, xfdesktop and thunar-volman in particular) from ThunarVFS to GIO, bringing remote filesystems to the Xfce desktop. The panel has been rewritten from scratch and provides better launcher management and improved multi-head support. The list of new panel features is too long to mention in its entirety here. Thanks to the new menu library garcon (formerly known as libxfce4menu, but rewritten once again) we now support menu editing via a third-party menu editor such as Alacarte (we do not ship our own yet). Our core libraries have been streamlined a bit, a good examplle being the newly introduced libxfce4ui library which is meant to replace libxfcegui4.

Perhaps the most important achievement we will accomplish with Xfce 4.8 is that, despite suffering from the small size of the development team from time to time, the core of the desktop environment has been aligned with today’s desktop technologies such as GIO, ConsoleKit, PolicyKit, udev and many more. A lot of old cruft like has been stripped from the core as well, as has happened with HAL and ThunarVFS (which is still around for compatibility reasons).

Thanks to the awesome Transifex translation platform, our language teams have been able to update their translations at an incredible pace. Please include them when praising this release!

A complete list of all changes since the latest stable release is available on

http://mocha.xfce.org/documentation/changelogs/4.8pre1

Below you will find download information for Xfce4.8pre1. Please give our mirrors a few hours to synchronize. We hope you will enjoy this release, feel encouraged to blog and tweet about it! Feedback is welcome in all forms. Bugs can be reported in our bug tracker as usual. We need your help to make Xfce 4.8 our best release ever!

Kind regards and thanks to everyone who has contributed to this release,

Xfce 4.8 Schedule Changes

As the Xfce release manager, I’d prefer to be the bringer of good news. Unfortunately, we have to make some adjustments with regards to the Xfce 4.8 release schedule.

You may well remember last year’s chaos with the 4.6 release date. We’re trying our best not to repeat that and if it should happen again, we’ll at least keep you posted about the issues as good as we can.

So, what’s the deal with 4.8?

One thing that hasn’t changed much is that our development team is very small. A hobby project of this size requires a certain amount of time to be invested by each individual developer. Time not everyone has as much has he would like to dedicate to Xfce.

Today, Brian announced his absence for the coming months due to his new job, leaving 2-3 of our core components (xfdesktop, xfconf and xfce4-session) more or less unmaintained (aside from bugfixes). The good news is that Jérôme (who has recently started to improve xfce4-settings and port xfce4-session to libxfce4ui) and Daniel (the maintainer of the thunar-shares-plugin) have offered their help with xfdesktop and xfce4-session.

Brian is not the only one having little time at hand though. I’m preparing myself for my final university exams, so ideally I’d be sticking my nose into lecture notes all day long. I still have the time to write mails like this but there hasn’t been much activity around thunar and related projects lately.

Again, I’m really happy to see people volunteering to help because that’s what we need right now. There’s a lot left to do before we can release 4.8. Let me get to that now.

As some of might have heard, thunar was ported to GIO this summer. Through GVfs, GIO brings new features such as SMB, SFTP, FTP browsing which some people use one a daily basis already. Now, GVfs has turned out to be problematic for us for various reasons. At first it shipped a HAL-based volume monitor with a hard-coded dependency on gnome-mount. Today it ships a volume monitor based on gnome-disk-utility (uses DeviceKit-disks itself) which proves to be inconsistent and somewhat incompatible to the HAL mounting code in exo.

The result: thunar-volman (not part of the core but important for thunar nonetheless) and xfdesktop will have to be ported to udev (the mounting being done with GIO, ideally). I’ve started working on this but this is far from being finished.

Question to the other developers: Didn’t xfce4-session use HAL for logging out and stuff? We might have to look into replacing those portions of code with something based on ConsoleKit, I guess?

HAL/udev is not the only issue however. With Xfce 4.8 we’ll be replacing libxfcegui4 with a new library called libxfce4ui. Not all core applications (again, xfdesktop being one of them, I think) have been ported to it yet. In most cases, this is no big deal and probably could be resolved within a few days though.

Then we have garcon, the much improved menu library that is supposed to replace libxfce4menu. At the time of writing the only feature it is lacking that is crucial for 4.8 is file system monitoring. We’ll probably implement basic monitoring like we had in libxfce4menu. Work on this hasn’t started yet.

Also, xfdesktop needs to be ported not only from ThunarVFS/HAL to GIO/udev but also from libxfce4menu to garcon.

So, as you can see there is quite a lot of work ahead of us. Taking into account the little free time some of us have these days, we’ve decided to postpone the 4.8 release until June 12th instead of April 12th. The entire release phase in our schedule has been moved by two months in time, as you can see on the official schedule wiki page:

 http://wiki.xfce.org/releng/4.8/schedule

To be honest, I wouldn’t consider this new date fixed either. It all depends on how much we can do until the feature freeze on April 1st. I’m optimistic that meeting the deadlines is possible though.

For all of you who can’t wait until June, try out our development releases which are announced on http://identi.ca/xfce. I have at least something good to share: For a few weeks now I’ve been running Fedora 12 with a mixture of Xfce 4.6 packages and development package from the upcoming 4.8 series and the new components have proven to be very stable already.

I’m especially happy about the new panel which works almost flawlessly (except for a few dual head issues) and not only supports real transparency and more comfortable launcher creation based on garcon, but is also compatible to panel plugins written for Xfce 4.6. (Good work, Nick!)

So, I guess this is it. A mixture of good and bad. I hope nobody is too disappointed. As always, we’re doing the best we can.

Cheers!
