[09:37] <cheche> Hi, we notice an performance regresion on ubuntu 12.04  after the upgrade Thunderbird 31.6.0+build1-0ubuntu0.12.04.1 ->  38.2.0+build1-0ubuntu0.12.04.2
[09:39] <cheche> We can downgrade to 11.0.1+build1-0ubuntu2 but it would be nice to have a newer version on our system
[09:52] <nikolam> cheche, isn't that question for Mozilla, e.g. why newer Firefoxes are slower then previous ones?
[09:54] <cheche> nikolam: well, I do not know...
[09:55] <cheche> nikolam: Still, I try to hold the 11.0.1 version on that system, but some how it get upgraded.
[09:57] <cheche> why ubuntu upgrade thunderbird to 38.x.0 instead of stick with 31.x.0?
[09:57] <cheche> 31.8.0 was released on 15-Jul-2015
[10:08] <nikolam> Because it is ESR release and needs less maintaining because upstream all is done is security patching and no features?
[10:08] <nikolam> also less testing because not big patches?
[10:09] <cheche> thunderbird does not have ESR version anymore https://www.mozilla.org/en-US/thunderbird/organizations/
[10:10] <nikolam> as far as I know newest LTS is now following newest Firefox, correct me if I am wrong (e.g. see in packages.ubuntu.com)
[10:10] <cheche> but I am talking about thunderbird nikolam
[10:10] <nikolam> thats because Thunderbird IS ESR mode for some time.
[10:11] <nikolam> ah Tb then. Well, Mozilla announced few years ago that Thunderbird is good enough for changing it big time, so TB is updating but slowly, so ESR is not needed
[10:12] <nikolam> It's good enough for me. sry for not seeing it's TB
[10:16] <cheche> nikolam: hye no problem :-)
[10:17] <nikolam> I plan as a user to use TB myself for a very very long time. I think it's not going anywhere, that's for sure.
[10:20] <nikolam> when I previously used Seamonkey Mail, I used to switch platforms like 8 times or something between Linux and Windows, using same data for mail (just changing prefs.js paths) That is what I like about truly multiplatform apps And I am now on Openindiana/illums(Solaris) with TB ;)
[10:56] <cheche> now that Debian drop the SPARC support, those efforts will go to Openindiana/illums :-)
[10:56] <cheche> nikolam: how can ensure that thunderbird does not get upgraded
[10:56] <cheche> I am sure that I hold that package yesterday.
[10:57] <cheche> but this morning it was upgraded
[10:58] <nikolam> why it wouldn't get upgraded? It receives security updates. You can be mostly sure it wont' be upgraded largly as an app, because it'e development is slow, because it is already very good at working what it does.
[10:58] <nikolam> Whole point of distributions is to have upgraded apps for free included inside distro
[10:58] <cheche> I only want to hold the thunderbird package to the 11.0.1 version
[10:59] <nikolam> if you stay as same distribution release/LTS version, all you have to do is use dpkg to lock it's version
[11:00] <nikolam> But on your place, I would actually measure what is exactly slower and go with that data to Mozilla
[11:00] <cheche> nikolam: I was using aptitude
[11:00] <nikolam> aptitude and apt are nicer way to do dpkg
[11:01] <cheche> I had dold the thunderbird package, but the system ignores me the next day
[11:02] <cheche> I had hold the thunderbird package, but the system ignores me the next day
[11:02] <nikolam> try asking on #ubuntu My suggestion is not to hold on old Thunderbird, for security reasons.
