Fail2Ban vs CRI-O: at a glance
What is Fail2Ban?
Fail2Ban's last release was an interim beta 14 months ago; the feed spans eight years in six entries.
Fail2Ban has published one release since April 2024, and it was explicitly labelled an interim beta. The six most recent entries cover eight calendar years — 1.1.1.beta0 in June 2025, 1.1.0 in April 2024, then two 1.0.x releases from late 2022 and a pair of 0.10/0.11 releases from 2020. Every entry defers its substance to a linked ChangeLog, so the feed itself carries version numbers, joke release names and little else.
What is CRI-O?
Patch tags land monthly with release notes that itemize nothing.
The three most recent CRI-O entries are v1.34.11, v1.34.10 and v1.33.13, cut roughly a month apart across two supported minor lines. All three carry auto-generated notes whose 'Changes by Kind' sections are empty or labelled Uncategorized, with the body given over to download bundles, checksums, SPDX manifests and signatures. Only v1.34.10 admits to a Bug or Regression category, and does not say what it was.

Fail2Ban's last release was an interim beta 14 months ago; the feed spans eight years in six entries.
◆ Current state
Fail2Ban has published one release since April 2024, and it was explicitly labelled an interim beta. The six most recent entries cover eight calendar years — 1.1.1.beta0 in June 2025, 1.1.0 in April 2024, then two 1.0.x releases from late 2022 and a pair of 0.10/0.11 releases from 2020. Every entry defers its substance to a linked ChangeLog, so the feed itself carries version numbers, joke release names and little else.
◆ Where it's heading
The stated purpose of the last substantive release was Python 3.12 and 3.13 compatibility, which is maintenance to stay installable rather than development. Release intervals have widened from months to years, and the most recent tag is a beta that has not been followed by a final. On the evidence here, the project is in preservation mode.
◆ Prediction
The most likely next event is another compatibility release triggered by a Python version that breaks the current code, not a feature release. Whether 1.1.1 ever leaves beta is not something these entries indicate — no further tag has followed it in over a year.
CRI-O
2.5INFRA · APIS
Patch tags land monthly with release notes that itemize nothing.
◆ Current state
The three most recent CRI-O entries are v1.34.11, v1.34.10 and v1.33.13, cut roughly a month apart across two supported minor lines. All three carry auto-generated notes whose 'Changes by Kind' sections are empty or labelled Uncategorized, with the body given over to download bundles, checksums, SPDX manifests and signatures. Only v1.34.10 admits to a Bug or Regression category, and does not say what it was.
◆ Where it's heading
What the feed does show is release engineering: every tag ships static bundles per architecture with checksums, SPDX SBOMs and signing bundles, which is the supply-chain posture Kubernetes runtimes are now expected to hold. The absence of itemized changes means the actual runtime work is invisible here, so read this feed as a release calendar for the 1.33 and 1.34 branches rather than a changelog.
◆ Prediction
Expect the same monthly patch cadence on both maintained branches, with content that stays uncategorized unless the project changes how it generates notes.
