Hi everyone, Today marks the release of the third LTTng 2.12 - (Ta) Meilleure release candidate. The second release candidate was skipped as the configure script was garbled by my release script. I unfortunately noticed this after having pushed the tag... Mea culpa! Have a look at the first release candidate's release notes for an overview of the features introduced in LTTng 2.12. https://github.com/lttng/lttng-tools/releases/tag/v2.12.0-rc1 This release is named after "Ta Meilleure", a Northeast IPA beer brewed by Lagabière. Translating to "Your best one", this beer gives out strong aromas of passion fruit, lemon, and peaches. Tastewise, expect a lot of fruit, a creamy texture, and a smooth lingering hop bitterness. Of note, the tracker API was changed and the lttng-track(1) and lttng-untrack(1) man pages were updated to clarify the usage of the new uid/gid tracking feature. We have also integrated a number of bug fixes which made their way to the master branch as we continue to work on the LTTng 2.13 release.
