There is no Lightning 4.0

…but of course there is is a release for Thunderbird 38! Since the release date for Thunderbird has been postponed and in the meanwhile Firefox has released 38.0.1, Thunderbird will also be released as Thunderbird 38.0.1. Since the Lightning version is automatically generated at build time, we have just released Lightning 4.0.0.1. If you are still using Thunderbird 31 and Lightning 3.3.3, you will be getting an update in the next days.

The exciting thing about this release is that Lightning has been integrated into Thunderbird. I expect there will be next to no issues during upgrade this time, because Thunderbird includes the Lightning addon already.

If you can’t wait, you can get Thunderbird in your language directly from mozilla.org. If you do happen to have issues with upgrading, you can also get Lightning from addons.mozilla.org. The latest Seamonkey version is 2.33.1 at the time of writing, you need to use Lightning 3.8b2 in this case. For more information on compatibility, check out the calendar versions page.

As mentioned in a previous blog post, most fixed issues are backend fixes that won’t be very visible. We do however have a great new feature to save copies of invitations to your calendar. This helps in case you don’t care about replying to the invitation but would still like to see it in your calendar. We also have more general improvements in invitation compatibility, performance and stability and some slight visual enhancements. The full list of changes can be found on bugzilla.

If you are upgrading manually, you might want to make a backup. Although I don’t anticipate any major issues, you never know.

If you have questions, would like support, or have found a bug, feel free to leave a comment here and I’ll get back to you as soon as possible.
