Introduction
Time-based releases have been shown to produce the best quality free software. A time-based release is one that does not wait for features or bug fixes, but is based (as purely as possible) on time. This enforces discipline in introducing fixes, provides predictability, and allows for more regular releases. It is also the case that we will necessarily release earlier, and then rapidly, incrementally, bug fix releases based on the previous stable release. So, if you have a need for the very highest quality release, it may make sense to delay a move until the first or perhaps second minor point release.
- LibreOffice has bi-annual, predictable releases that are synchronized with other Free Software projects (e.g. Gnome) and are at least one month ahead of major Linux distribution releases.
- Synchronising the time-based release schedule with the wider Free Software ecosystem also has huge benefits in getting our new features out to users as quickly as possible, with a minimum of lag in the distribution cycle. As a result, we are aiming for six monthly releases, in February and August.
- There are two versions available: the latest release for technology enthusiasts, early adopters and power users, and the previous release - with fewer features but tested for longer - for corporate implementations and more cautious users.
- As a result, users get a new major release every six months with a wide range of features, fixes and enhancements. They will also receive many bug-fixing micro releases. The first X.Y.0 release is intended for early adopters. More conservative users are advised to wait for a later X.Y.3/X.Y.4 bugfix release.
Note that the dates in this schedule may change if there are serious technical or other problems with the release. An extra RC might be needed if the final release candidate has a catastrophic problem. Such a problem could delay the final release by a week or more. The decision should be made at a meeting of the Engineering Steering Committee.
The simplified graphic below shows three releases placed on a timeline consisting of 24 months.

Dates
The release is time-based but the schedule defines calendar weeks instead of exact dates. It is because we are always a bit flexible. The release can be delayed by few days because of blocker bugs, build problems, and other technical issues.
The release consists of several beta and release candidate builds. There are needed several actions for each build. The ideal workflow looks like:
- Monday: commit deadline; reminder is sent to devel, l10n mailing list before it happens
- Tuesday: the tag is created on a commit that builds and passes unit-, subsequent-, and smoke-tests; tag is announced on the devel and qa mailing lists
- Wednesday: builds are uploaded on the early pre-release site; they are announced on the devel and qa mailing lists
- Thursday: builds are uploaded on mirrors. They are announced via many channels, e.g. mailing lists, twitter
- Friday: builds are available via the official pre-release site
The final release is usually announced on Thursday, few days after the final release candidate is out.
Note that we are very strict about commits to the final release candidate, so full regression test is not needed. It is used as the final build when it passes the needed tests. It is just renamed on mirrors.
Schedule
The schedule is based on the following rules:
- do the major release every six months and synchronize it (at least one month ahead) with major Linux distributions; it always comes with a wide range of features, fixes, and enhancements
- do a pure bugfix release every month after the main release until it is good enough even for the most conservative people; do it less frequently afterwards
- do pure bugfix releases, including security fixes, until the next release is ready for most conservative people
- do not do two builds the same week.
The result is the following template:
| Event | Summer | Winter |
|---|---|---|
| x.y feature freeze | Jun(b) | Dec(b) |
| x.y.0 first release | Aug(b) | Feb(b) |
| x.y.1 bugfix release | Sep(b) | Mar(b) |
| x.y.2 bugfix release | Oct(b) | Apr(b) |
| x.y.3 bugfix release | Nov(b) | May(b) |
| x.y.4 bugfix release | Dec(b) | Jun(b) |
| x.y.5 bugfix release | Feb(m) | Aug(m) |
| x.y.6 bugfix release | Apr(m) | Oct(m) |
Where (b) means the beginning of the month, (m) means the middle of the month and (e) means the end of the month.
String freeze
The release plans for the first version of each major release indicate a "hard English string & UI freeze". The idea is to make the lives of translators easier. The translators should be able to trust that no new translatable strings are added into the UI or Help files between the period of the string freeze and release.
In practice, you should keep an eye on the tagging of the first release candidate. One way to find out, if RC1 has been tagged is to visit the tag view of the LibreOffice core repository in Gerrit and input into the filter field: libreoffice-X.Y.Z. If the results do not contain any entry for libreoffice-X.Y.Z.1, RC1 has not yet been tagged and string changes can still be committed.
After the first version of a major release is out, correcting mistakes in the UI and Help strings is fine. Any completely new content should target the next major release.
Version scheme
We do several builds around each release. The following versioning scheme is used:
- X.Y.0.0.alphaZ - Zth alpha version of the initial release
- X.Y.0.0.betaZ - Zth beta version of the initial release
- X.Y.0.Z - Zth release candidate of the initial release, last rc is considered as final and put on the main download page
- X.Y.1.Z - Zth release candidate of the 1st bugfix release, last rc is considered as final and put on the main download page
It seems to be the best compromise with the following advantages:
- easy to understand for normal users, alpha, beta flags are known from other projects, so they set reasonable expectations
- correct alphabetical sorting in RPM, Bugzilla
- “easy” to parse (alpha/beta strings delimited by dot)
There was a long discussion about this scheme on the mailing list.
Accelerating the release cycle
This acceleration of the release cycle involves some considerable release engineering and QA effort. To reduce the cost of these, we work to provide complete (ie. containing all languages) daily snapshots of the master branch to allow continual testing of code improvements. This works partially already, as can be seen/downloaded from here.
Similarly, we plan to increasingly automate the build process to allow a much lower-touch release flow, and to continue to shrink the footprint of our binaries to allow far more rapid transfer of product-equivalent builds.
End-of-Life Releases
A release normally has a lifetime of around nine months. We consider a release to have reached its End of Life (EOL) one month after the last planned release.
If you want longer term support for a release, you’re encouraged to engage any certified L3 provider who could provide you with the service.
Because of the amount of data, the releases were split out to ReleasePlan/Archive.
