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 YARA?

YARA ships bounds checks, not features — three patch releases published thirteen minutes apart.

Every release in this window is memory safety work on the parsers. The July batch bounds the rule table index in two opcodes, the tilde stream row count in the dotnet module and the repeat stack depth in the regex fiber sync, and fixes a leak in rule stream loading. Earlier releases closed a heap overflow triggered by hand-crafted compiled rules, infinite loops on corrupt PE resource directories, and an integer overflow in ELF parsing. The three most recent tags were published within thirteen minutes of each other.

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.

5.0

YARA ships bounds checks, not features — three patch releases published thirteen minutes apart.

◆ Current state

Every release in this window is memory safety work on the parsers. The July batch bounds the rule table index in two opcodes, the tilde stream row count in the dotnet module and the repeat stack depth in the regex fiber sync, and fixes a leak in rule stream loading. Earlier releases closed a heap overflow triggered by hand-crafted compiled rules, infinite loops on corrupt PE resource directories, and an integer overflow in ELF parsing. The three most recent tags were published within thirteen minutes of each other.

◆ Where it's heading

YARA is being maintained as an input parser under adversarial pressure rather than developed as a language. The last release to add anything — 4.5.0, with unreferenced string rules, strict escape warnings and a slow-rule callback — is nearly two years back, and everything since has been bounding a value someone found a way to overflow. Even the scan limit change was a revert to a prior default.

◆ Prediction

Expect the pattern to hold: batched patch releases whose contents are bounds checks in the PE, dotnet and regex paths, since that is where every recent finding has landed. Nothing in these entries suggests new language or module capability is queued.
