A young ML metrics package rewrote its own backend twice in six months chasing speed.
A side-by-side editorial comparison of dockViewR and Fail2Ban — release velocity, themes, recent moves, and the top alternatives to consider.
Draggable dock panels for Shiny, learning that layout state belongs on the client
dockViewR wraps the dockview JavaScript library so Shiny apps can offer draggable, splittable, tabbed panel layouts — the IDE arrangement, driven from R. Three releases since May 2025 have taken it from a working widget to one with a proper server-side control surface: panels can be added, removed, selected and moved from the server, and the dock exposes a reactive proxy.
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.

The design has been converging on the standard htmlwidgets pattern, and 0.3.0 is where it commits. Earlier releases routed panel-id checks through Shiny inputs, which meant the state was stale until the next reactive flush and forced awkward workarounds when manipulating the dock inside observeEvent(). Moving those checks to the browser and adding dock_view_proxy() drops that class of bug entirely, at the cost of a breaking API change and a dev-mode option for surfacing the warnings.
Having taken one breaking change to reach the proxy idiom, the natural follow-on is filling out the proxy surface so every panel operation is reachable through it.

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.
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.
