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 NumPy and Pelican — release velocity, themes, recent moves, and the top alternatives to consider.
NumPy cut distutils loose and is quietly rebuilding for free-threaded Python.
NumPy is in the maintenance rhythm of a foundational library: a transitional minor release followed by a run of patch releases cleaning up what it broke. 2.5.0 removed distutils, expired a large batch of 2.0-era deprecations, and dropped Python 3.11. The patch line since has been about compatibility surfaces — a Cython datetime API fix so downstream can still target pre-2.5, a GCC minimum bump, and wheels for Python 3.15 release candidates.
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.

Two forces are steering releases. One is Python itself: NumPy is tracking 3.15 before it ships and steadily improving free-threading support, including fixing an ABI leak in the free-threading-compatible stable ABI. The other is the array-api standard, which is pulling NumPy's own semantics into line — descending sorts landed for exactly that reason.
Expect the 2.5.x line to keep absorbing free-threading and Python 3.15 fallout; the entries suggest the interesting work now happens at the C API and build-system layers, not in array semantics.

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.
