1.0 Beta 1 Progress

We are working hard on getting the first release candidate for Sunbird and Lightning 1.0 Beta 1 out and since our nightly testers have surely noticed that the latest nightlies have been named “1.0b1pre” I wanted to give a short update.

We have been working on releasing the beta since last Wednesday. To make releasing easier, we have decided to make use of the Thunderbird release automation scripts. This is also the reason the version number changed to 1.0b1pre. Since the directory structure of Calendar is a bit different to what Thunderbird and Firefox use, we had some complications that need to be mangled out first. Unfortunately, building is a lengthy process (it takes a while until we are able to find out what went wrong) and Mozilla Messaging’s Release Engineering is in a different timezone (6 hours difference), things are taking a bit longer than I anticipated.

Nevertheless, I am confident that we will be able to publish our release candidate in the next week, and depending on if we find further blocking issues or not, release 1.0 Beta 1 in the next 2-3 weeks. Also, for the next release the process should be much quicker since we’ve now had the time to take care of the one-time issues (missing access, minor bugs in our build system, etc.)

Update: Linux and Windows builds of RC1 have succeeded! The fix for Mac is on its way, we now just need to take care of some branching issues and let the Mac box build.


  1. I’m really looking forward to the beta release! I’m currently having an issue with google calendars set to Cached. If I set them as cached, then each calendar shows all the events for all other calendars. So if I have 3 calendars (set to cached), I see each event 3 times, one for each calendar color. If I set the caching off and restart, then it’s back to normal (but I lose the caching functionality of course).

  2. Ed, take a look at this bug. Unfortunately the fix for this bug is quite a substantial change, so we can’t take it for 1.0b1. I hope the uncached mode is sufficient for now though.

  3. Hello,
    Keep up the good work.
    I have two questions:
    1. How do you forward an event to someone else?
    2. I have a version of 20091126033329, and I have no alarms popping up against a Caldav calendar.
    If you want I can turn debug mode on if you need log or …do not hesitate
    Kind Regards

  4. Hello
    First of all, I would thank you for your good work
    Then I have one question and possibly one bug
    Q: How do you forward an event to someone?
    B: No Alarm is popping up for event with a Caldav Calendar.
    Thunberbird 3.0 RC2
    Lightning 1.0pre 20091126033329

  5. Great, looking forward to the release… I’m using 64-bit Ubuntu so I can’t really use the Nightly. Have a couple of Mac users that can’t open my invitations now, it has been fixed for > 1 year; but it’s not in 0.9…
    Keep up the good work!

  6. Great work! Thanks for all the effort. TB&Lightning&Gdata&Googlecal are central to my daily planning.
    (PS: Thanks for fixing ‘[Bug 523987] Dismissing alarms doesn’t work with Provider for Google Calendar’.)

  7. One annoying thing I noticed a few days ago was when Sunbird nightlies of the comm-1.9.1 branch were “demoted” from 1.0pre to 1.0b1pre, causing “version incompatibilities” in extensions (including Mozilla’s own DOM Inspector) which have 1.0pre as their minVersion for Sunbird.

    Where I can find the right release for TB 3.1a1pre?
    Or I can safely edit install.rdf from 1.0b1?

  9. today (december 8th 2009) thunderbird 3.0 final is gonna be published. i wonder what happens with the still nonexistant final calendar/lightning/sunbird that would work together normally without beta/nightly messing or xpi patching/editing etc.
    please act at last and speed up your development and release processes. lightning development process is really a nightmare. get some funding and hire some people who know what they are doing.
    why thank you.

  10. hi i just update thunderbird and i can not use lightning 9.0 how can i recover my data

  11. use the nightlies of calendar xpi at
    to make it work with the thunderbird 3.0 final.
    what a pitty that calendar team dudes work so slowly and missed the target date for the final thunderbird 3.0
    sunbird lightning calendar what a mess even with their project subproject codenames and so forth.
    guess microsoft is the better guys with their outlook and exchange solution. you cant beat em. at least calendar and mozilla messaging dudes just dont seem to be eager enough to become a real competition.

  12. Hello Folks,
    unfortunately, its not so easy as you make it sound. Funding a single developer full time can mean at least 60k per year. Thats not an amount of money easily spent.
    We are working on 1.0b1, but we don’t have the manpower to synchronize our releases with Thunderbird and I don’t think that is what you should expect.
    Of course Microsoft has a good standpoint, they have paid developers, release engineering, user experience and QA, but remember they also sell their Product for a retail price of currently $109.95. Would you, and do you think everyone else would be willing to pay this price for a full Lightning version? I believe not.
    I will post an update shortly, the short version is we are working on making the buildbots produce the builds, but are still stumbling upon many errors. These will not show up for the next release, but this time it will take a bit longer.
    Thank you for your understanding,

  13. I just upgraded to Thunderbird 3 and, of course, I wanted to have Lightning.
    I gave a try to the nightly build but I could not install it (not a supported version?).
    Would you please fix the nightly build so it can be installed with TB 3.
    I understand you are a small team and can not release the final release with TB but having the nightly alternative would be a plus!

  14. the nightly xpi needs to get downloaded to your desktop for example. and then drag/drop it to your extensions window inside thunderbird.
    it always works like this. i have nightlies installed and running fine in tb 3.0

  15. friteninnitelylitenin

    Just drag the link to the XPI from Firefox to Thunderbird Add-ons. I don’t know why Mozilla keeps telling people to download when drag&drop just works.
    The RC builds don’t seem to be up yet, or am I looking in the wrong place?

  16. Thanks for all your work on Lightning. I’ve become very dependent on Lightning and wish the Thunderbird team or someone would have warned about the incompatibility issue. I would not have updated Thunderbird. When the new RC is ready will it detect our data?

  17. Unlike some of the others that have posted I was told by Thunderbird that Lighting wasn’t supported when I installed. I installed anyway after reading this site expecting I could use the nightly builds. I haven’t yet been successful and was hoping I might get a little assistance. I have downloaded the extensions from the build site and saved those to the extensions folder. Every time I start Thunderbird it says I have two extensions and ask if I would like to install them, I do and then try to configure them and Thunderbird tells me they are not compatible. Any thoughts on what I am doing wrong? (Win7 64bit)
    Keep up the great work Lighting team. I get Outlook for free and still won’t use it and really look forward to getting Lightning back up and running.

  18. Yea!!!! Downloaded the most recent nightly, dragged it into the Add-ons/Extensions window, rebooted and there it was!!!!
    Thanks you, Thank you, Thank you…..

  19. I find it a little bit ‘off’ that people are criticising the slower release pace than that of Thunderbird. What we pay (ie nothing) and what we get (something that is arguably a much better product that it’s main competitor) are the important things.
    Granted, those using TB/Lightning for work might find it unrealistic to be without their calendar, but this can be solved fairly easily.
    Keep up the good work guys!

  20. How are you guys managing to get the nightlies installed? I tried with 12/09, and now again on 12/10; drag and drop to the TBird 3.0 Add-ons window; and I get:
    Provider for Google Calendar 0.6pre could not be installed because it is not compatible with Thunderbird 3.0.
    Lightning 1.1a1pre could not be installed because it is not compatible with Thunderbird 3.0.

  21. The synchronization with Caldav doesn’t work anymore with the last nigthly ( worked fine with lightning 0.9 on TB 2)

  22. hudus: Thanks. [I was using http://ftp.mozilla.org/pub/mozilla.org/calendar/lightning/nightly/latest-comm-central/win32-xpi/%5D
    Btw, the Install would not process with just a restart of TB; it took a reboot. But I have my Google Calendar now in Lightning and I’m happy.

  23. Found a bug..
    The right-click doesn’t work in the today pane…
    dunno for whatever reason.
    The window still shows up, but I can’t edit for example per right-click the progress of tasks!

  24. err sorry forgot to post my specs…
    Tb 3.0 final
    lightning nightly win32-xpi
    Win7 x64

  25. When will there finally be Linux/x86_64 builds?

  26. To those who wrote comments within hours of the TB3 release accusing the lightening developers of being slow and of having missed the deadline, have clearly never worked on a software release cycle or managed any complex project for that matter. You are right the team here are not microsoft, if that is what you want then you have an easy alternative. Managing such a process is very stressful and intense work, perhaps you’d might bear the impact that such pointlessly negative comments have during this period.
    To the developers keep up the great work, you should be proud to have achieved such a great piece of software. When your happy that it all works we’ll be very happy to receive it.

  27. Regarding the Lightning 1.0 beta.
    Will there be a Swedish localization available for the first beta?

  28. I finally got the lightning nightly win32-xpi working with TB 3.0 and Firefox 3.5.5; the reboot was critical.
    But, when exporting the calendar to a csv file it seems not to include repeated tasks. Can they be included?

  29. Thanks to the calendar developers, we appreciate the work that you do. Got my calendar working in Seamonkey 2.0 too and it looks good so far.

  30. I’m saddened by all those who complain about release schedules from a team of people who do it in their spare time on a product that’s free!
    If you want to be locked into a microsoft solution, by all means, go ahead, spend your money.
    I’m happy just to use sunbird with it’s little quirks and when-ever they get fixed, all the better.
    Lets be honest here – if your running a large enterprise then you really wouldn’t be running with these solutions because they are not there yet – so accept happily the great work done and contribute yourself if you want things sped up in terms of release times and bug fixes – otherwise smile and say thank you – it’s not hard – lets try that now shall we? Repeat after me, THANK YOU.
    Stop whinging and contribute people!

  31. i drag the Lightning file to the extensions window, but a popup window apeare and tell me if i want install the Lightning and when i click install recive the error messages about i can´t install this en TB 3.
    and i don’t have other option.

  32. Using Lightning 1.0b2pre in TB 3.0 and I am quite happy with it. I have one problem, but cannot report in BugZilla as that is apparently for released software only.
    I sort the task list on multiple columns from main to minor: Priority, Status and Title. The problem is that when I switch to the calendar tab and then back to the task tab the sort order is lost again.
    Another real problem is that I cannot print the task list.

  33. Dempsey, you can also use bugzilla for development versions. Please check if the bug is not already filed and then file it under Product Calendar. Printing tasks is bug 325137.
    Miami, the nightly versions for Thunderbird 3 are available at ftp://ftp.mozilla.org/pub/calendar/lightning/nightly/latest-comm-1.9.1/
    Robert K, recurring events are not easily exported. There is no easy way to export the recurrence info into csv, so in the best case only the first occurrence can be exported. Please check bugzilla for a bug if this is not the case.
    Stefan21, unfortunately, sv-SE won’t be part of beta 1. There are some missing strings that were not translated. See http://l10n.mozilla.org/dashboard/?tree=sunbird10x for more details. If you would like to contribute to the swedish localization, please contact their localization team, see https://wiki.mozilla.org/L10n:Localization_Teams#Swedish_.28sv.2Csv-SE.29
    All, there will probably be *contributed* Lightning 64 bit releases for the final 1.0b1 release, but unless we get 64 bit hardware its unlikely that we will have nightly builds.
    pierre, please enable calendar.debug.log and calendar.debug.log.verbose and check your error console. If the problem persists, please use either getsatisfaction.com/mozilla_messaging or bugzilla to report your issue. Please include details about your caldav server.

  34. For some reason I can’t load my google calendar into the 1.0beta lightning. I can go through the process and put in the ics url and the “next” button activates but when I push it nothing happens.

  35. I have the same bug as “nathaneik”:
    >Found a bug..
    >The right-click doesn’t work in the today pane…
    >dunno for whatever reason.
    >The window still shows up, but I can’t edit for example > > per right-click the progress of tasks!
    20100111 Lightning/1.0b1 Thunderbird/3.0.1
    It’s seems to be introduced in 1.0 version, earlier was working for me.

  36. I cannot print from lightning 1.0b in TB 3.0
    The program san’t seem to find my printer. I am running Windows 7 home premium.everything else works fine.

  37. Satisfactory blog, some interesting information. I remember 9 of days ago, I have found a similar post. Does anyone know how to track future posts?
