SeaMonkey and the future

Wow! A new release and two news items together. What is cooking?

With the SeaMonkey 2.49.5 release the 2.49.x line comes to an end. Unless a catastrophic bug is discovered 2.49.5 will be the last ESR 52 based version. Backporting security fixes and at the same time working on the next, already overdue, major release is not possible with the few remaining developers.

Plans are to do further interim 2.53 versions based on a much enhanced Gecko 56 base while working on bringing you the next ESR 60 based 2.57 version. After 2.57 we will decide about the future. The current Mozilla Gecko codebase has seen a flow of constant major changes and api removals in the last 2 years and is no longer really usable for our needs. By the end of the year the SeaMonkey project is expected to be completely independent of Mozilla. We will see how this pans out but we are doing our best and already have a new infrastructure in place where we do builds and website hosting.

We would also like to remind everyone again that this a community project independent of Mozilla. So if you want to continue seeing future SeaMonkey releases please help by either donating money or even better help out with development. We are still committed and hope you are too.

SeaMonkey 2.49.5 released

The SeaMonkey project is proud to present SeaMonkey 2.49.5: The new release of the all-in-one Internet suite is available for download now! Based on Mozilla Firefox 52.9 ESR and further enhanced, it delivers those same developments in web technologies such as HTML5, hardware acceleration and improved JavaScript speed.

SeaMonkey 2.49.5 is available in 20 languages, for Windows, macOS x64 and Linux.

Automatic upgrades from previous versions are, for most configurations, disabled for this release. If you need to upgrade from an earlier version, please download the full installer from the downloads section and install SeaMonkey 2.49.5 manually over the previous version.



This release adds officially supported Windows x64 and Linux x64 versions. If you want to install the Windows x64 version please download the full installer and uninstall the old x86 release first. Your profile data will be kept during an uninstall. Support for the macOS x86 unified binary was dropped because we are now using a more current macOS development environment.

Help squashing bugs in mail and news

Our Thunderbird friends ask for help squashing bugs. If you have some spare time help them and also us because SeaMonkey and Thunderbird use a shared codebase for mail and news.

Some Details from the announcement:

We are grateful to have a very active set of users who generate a lot of bug reports and we are requesting your help in sorting them, an activity called bug triage. We’re holding “Bug Days” on (all day, EU and US timezones) and (EU and US timezones until 4pm EDT). During these bug days we will log on and work as a community to triage as many bugs as possible. With several of us working at the same time we can help each other in real time – answering questions, sharing ideas ideas, and enjoying being with like-minded people.

No coding or special skills are required, and you don’t need to be an expert or long term user of Thunderbird. Some things you’ll be doing if you participate:

Help other users by checking their bug reports to see if you can reproduce the behavior of their reported problem.

Get advice about your own bug report(s).

Learn the basics about Thunderbird troubleshooting and how to contribute.

But we hope you’ll join us on the 8th or the 13th via #tb-qa on Mozilla’s IRC so that we can put these bugs in their place which helps make Thunderbird even better. If you have any questions feel free to email Ryan.

Visit the Thunderbird Blog to see the full announcement.

Today is "I love Free Software Day"

And if you are wondering when the next release will be out, then read about the progress we are making in our SeaMonkey Project Blog.
