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 OctoPrint?

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

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.

2.5

OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.

◆ Current state

The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

◆ Where it's heading

Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.

◆ Prediction

Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
