oslo.service 4.4.1 (gazpacho)
by no-reply＠openstack.org 19 Nov '25

19 Nov '25

We are happy to announce the release of: oslo.service 4.4.1 This release is part of the gazpacho release series. The source is available from: https://opendev.org/openstack/oslo.service Download the package from: https://pypi.org/project/oslo.service Please report issues through: https://bugs.launchpad.net/oslo.service/+bugs For more details, please see below. 4.4.1 ^^^^^ Upgrade Notes * The "ThreadGroup.max_threads" attribute has been restored for backward compatibility. It previously disappeared during the backend refactor (commit "8c74d0718dc11ed5"), which caused consumers such as Heat to fail when upgrading to oslo.service 4.4.0. The attribute now maps to "thread_pool_size" and emits a "DeprecationWarning". Applications should migrate to "thread_pool_size". The deprecated attribute may be removed in a future release.

kolla 21.0.0 (flamingo)
by no-reply＠openstack.org 19 Nov '25

19 Nov '25

We high-spiritedly announce the release of: kolla 21.0.0 This release is part of the flamingo release series. The source is available from: https://opendev.org/openstack/kolla Download the package from: https://tarballs.openstack.org/kolla/ Please report issues through: https://bugs.launchpad.net/kolla/+bugs For more details, please see below. 21.0.0 ^^^^^^ Prelude The Kolla "21.0.0" (Flamingo) release modernises the base operating systems and core infrastructure shipped by the containers. Highlights include: * Rocky Linux 10 replaces Rocky Linux 9 as the only supported Rocky base image, removing the Delorean/CentOS Cloud SIG dependency and tightening RPM repository handling via "repos.yaml" (including a new versioned Erlang source for aarch64). * Data-plane services received major upgrades: "MariaDB" now tracks the 11.4 LTS series with the upstream health check script and the legacy clustercheck image removed, "ProxySQL" moves to 3.x, "Bifrost" consumes Ansible 11, "RabbitMQ" advances to 4.1, and "Gnocchi" is updated to 4.7.0. * Observability components were refreshed with "Fluentd" 6.x LTS, "OpenSearch"/"OpenSearch Dashboards" 3.x, broad "Prometheus" exporter and infrastructure bumps ("etcd", "helm", "letsencrypt- lego"), and the retirement of the "collectd", "telegraf", and "prometheus-ovn-exporter" images. * The container portfolio was streamlined: support landed for the "ironic-pxe-filter" image and "neutron-metadata-agent" wrapper scripts, while dormant services such as "ironic-inspector" and "Venus" were dropped. Changes in kolla 21.0.0.0rc1..21.0.0 ------------------------------------ 0ac3424e9 Update TOX_CONSTRAINTS_FILE for stable/2025.2 2e0e5a082 Update .gitreview for stable/2025.2 Diffstat (except docs and test files) ------------------------------------- .gitreview | 1 + tox.ini | 6 +++--- 2 files changed, 4 insertions(+), 3 deletions(-)
