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 plogr?

A logging header for Rcpp packages that sat untouched for nine years, then changed how it switches on

plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.

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.

A logging header for Rcpp packages that sat untouched for nine years, then changed how it switches on

◆ Current state

plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.

◆ Where it's heading

There is almost no trajectory to read here, which is itself the finding — the package was finished in a week and stayed finished. The 2025 release is the first change in nine years and it tightens the activation contract: logging now does nothing unless PLOGR_ENABLE is defined at compile time, so packages depending on it get silence by default rather than unexpected output. A GCC-specific fix for function names in multi-argument template classes lands alongside.

◆ Prediction

With the activation macro now explicit, dependent packages that assumed logging was on will need to define it; beyond that the entries give no basis for expecting further development.
