Fail2Ban vs Redocly: at a glance
What is Fail2Ban?
Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
What is Redocly?
Redocly makes its docs agent opt-out, and breaks configs that still use enabled.
Redocly shipped four platform builds and a config release on November 3. Config 0.71.0 replaces enabled with disabled across platform.agent, so every listed duty runs unless switched off and old configs fail validation. Platform builds redesigned deployment lint reports around APIs whose results changed, added Format Document for YAML, and fixed Webview reloads and CLI sign-in for users without an organization.

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door
◆ Current state
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
◆ Where it's heading
The pattern is long silences broken by releases that mostly absorb external change — Python 3.12 and 3.13 compatibility in 1.1.0, a Dovecot filter regression in 1.0.2 — with the substance deferred to a ChangeLog the feed does not carry. What is different this time is the contributor list, which runs to a dozen first-time contributors, suggesting the delay was throughput rather than abandonment. The release also had to be re-cut: the first Debian package shipped with wrong paths from a missing systemd-dev build dependency and was pulled and replaced.
◆ Prediction
Given the beta-to-final gap just closed and the volume of first-time contributors merged into it, the useful thing to watch is whether the next release arrives in months rather than years; the entries do not indicate what it would contain.
Redocly
6.3INFRA · APIS
Redocly makes its docs agent opt-out, and breaks configs that still use enabled.
◆ Current state
Redocly shipped four platform builds and a config release on November 3. Config 0.71.0 replaces enabled with disabled across platform.agent, so every listed duty runs unless switched off and old configs fail validation. Platform builds redesigned deployment lint reports around APIs whose results changed, added Format Document for YAML, and fixed Webview reloads and CLI sign-in for users without an organization.
◆ Where it's heading
After the reunite-to-platform rename, Redocly is reshaping config around the agent and making it the default. Around that, daily builds polish the editor and the lint workflow that governs API quality.
◆ Prediction
Expect follow-up platform builds that handle the enabled-to-disabled config change and more agent duty settings in the next config release.
