Unfortunately, some major errors slipped through in 1.0b4. You might have noticed the alarm window disappearing and a lot of misplaced beeps from the alarm system. You might have also noticed, that some of your calendars are no longer working (specifically, webcal:\/\/ calendars).<\/p>\n
To fix these issues we are releasing 1.0b5 in the next 1-2 days, which contains 10 bugfixes<\/a>.<\/p>\n As another highlight, 1.0b5 will now be compatible with both Thunderbird 5 and Thunderbird 6 to ensure you can continue using Lightning without extra hassle. If you are using Thunderbird 6.0b1 it would be great if you could give these test builds a spin.<\/p>\n Update:<\/strong> Another issue slipped in, I’ve modified the packages to fix it. If you have already downloaded, please try the following links!<\/p>\n You can get the builds here. If you get a 404, its likely they have not been propagated to all mirrors yet, check back in a few hours.<\/p>\n\n
