Undertow
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
A side-by-side editorial comparison of DOLFINx and Pelican — release velocity, themes, recent moves, and the top alternatives to consider.
A finite element library whose entire recent release history says 'you don't need this'.
DOLFINx is the computational core of the FEniCS finite element project, and every release in this window is a post-release — a re-tag carrying packaging or test fixes rather than functional change. Each one states plainly that users do not need to upgrade. The actual audience is Debian packagers, CI systems, and anyone building against a moved dependency like ADIOS2 2.11 or pytest 9.
Pelican now ships roughly once a year, and 4.12 is theme housekeeping
Pelican is a mature Python static site generator in low-cadence maintenance: 4.12.0 in April 2026 followed 4.11.0 by fifteen months, which itself followed 4.10.0 by sixteen. Nearly all recent work lands in the bundled notmyidea and Simple themes, in summary generation, and in the file-watching and logging plumbing. The contributor pattern is telling — a handful of names carry most merged PRs, and the changelogs read as accumulated small fixes rather than planned feature arcs.

This is a project with a slow, deliberate feature cadence and a fast reactive one for the build ecosystem around it. Real work lands in the sparse v0.10.0 and v0.11.0 tags; everything between is absorbing breakage from Python versions, test frameworks, and I/O libraries the project does not control. The post-release discipline — explicitly telling users to stay put — is itself notable.
Post-releases should keep appearing whenever a downstream build environment shifts; the next functional change would come with a new minor tag, and these entries give no signal on its timing or contents.

The project is stable rather than growing: the last genuinely structural changes were switching the build tool to PDM and moving file watching to watchfiles back in 4.9.0, and nothing since has altered how Pelican works. Recent releases invest in making the bundled themes usable as inheritance bases — more template blocks, CSS_FILE support, dark mode — which pushes customization toward theme authors instead of core. Expect continuity, not reinvention.
The entries show no roadmap signal beyond incremental theme and Python-version support, so the next release most likely follows the same pattern: another year-scale gap, more Simple-theme inheritance hooks, and test-matrix updates for a newer Python.
