OpenStack Releases
OpenStack Releases¶
Release Series¶
OpenStack is developed and released around 6-month cycles. After the initial release, additional stable point releases will be released in each release series. You can find the detail of the various release series here on their series page. Subscribe to the combined release calendar for continual updates.

Note
The schedule of Maintenance phases changed during Ocata and also during 2024.1 Caracal. The old phases were used until Newton. The last series that transitioned to Extended Maintenance was Xena. The replacement of Extended Maintenance process to Unmaintained was formulated in the 2023-07-24 Unmaintained status replaces Extended Maintenance resolution.
Note
If a branch is marked as Extended Maintenance, that means individual projects can be in state Maintained, Unmaintained, Last or End of Life on that branch. Please check specific project about its actual status on the given branch.
Series-Independent Releases¶
Some deliverables are released independently from the OpenStack release series. You can find their releases listed here:
Releases with Skip Level Upgrade Release Process (SLURP)¶
Releases can be marked as Skip Level Upgrade Release Process (or SLURP) releases. This practically means, that upgrades will be supported between these (SLURP) releases, in addition to between adjacent major releases. For example the upgrade paths starting with the 2023.1 Antelope release look like this:
![digraph openstack_releases {
label="OpenStack Upgrade Paths"
splines=false;
nodesep=1;
rankdir="LR";
node [shape=box];
A [label="2023.1\nAntelope"];
C [label="2024.1\nCaracal"];
B [label="2023.2\nBobcat"];
E [label="2025.1\nEpoxy"];
D [label="2024.2\nDalmatian"];
A -> C [xlabel="SLURP"];
A -> B;
B -> C;
C -> E [xlabel="SLURP"];
C -> D;
D -> E;

Cryptographic Signatures¶
Git tags created through our release automation are signed by centrally-managed OpenPGP keys maintained by the OpenStack TaCT SIG. Detached signatures of many separate release artifacts are also provided using the same keys. A new key is created corresponding to each development cycle and rotated relatively early in the cycle. (Implementation completed late in the Newton cycle, so many early Newton artifacts have no corresponding signatures.) Copies of the public keys can be found below along with the date ranges during which each key was in general use.
