A side-by-side editorial comparison of Astra and libvips — release velocity, themes, recent moves, and the top alternatives to consider.
Two release trains, zero new features — Astra has been in pure maintenance mode since spring.
Astra ships the free theme and the Pro add-on on parallel version lines that reuse the same numbers, so v4.13.7 exists in both trains weeks apart. The last six releases are fix rounds: Elementor color regressions, Stripe checkout blockers, shortcode output in the Header/Footer builder, PHP 8 text loss. The newest pair adds a security hardening fix to Pro's Site Builder and a lighter, correctly sized mobile logo.
libvips 8.18 opened up UltraHDR and Oklab, then spent months closing memory bugs.
The feed tracks release candidates only. The 8.18 line added UltraHDR load and save, Oklab and Oklch colourspaces, raw camera loading through libraw, and gainmap plumbing through thumbnail and dzsave. The most recent tag, 8.18.3-rc1, is a different kind of release: roughly two dozen fixes for out-of-bounds reads, heap overflows and null dereferences across the jp2k, HEIF, Radiance, Magick and PPM loaders.

The arc is stabilization, not expansion. Several releases exist only to undo damage from the previous one — 4.13.8 reverses an Elementor color change introduced in 4.13.7 — which points to a codebase absorbing the WordPress 7.0 admin transition and the surrounding plugin ecosystem rather than building on top of it. Compatibility work with Elementor, WooCommerce, and WPML dominates the changelog.
Expect the 4.13.x patch cadence to continue on both trains with compatibility and security fixes. Nothing in these entries signals a feature release, so when the next one arrives is not predictable from this feed.

The arc runs from capability expansion to hardening. Having taken on more untrusted input formats, libvips is now paying the cost of that surface in memory-safety fixes, several credited to external fuzzing and security researchers. Format reach and attack surface are growing together.
With 8.18.3-rc1 dominated by loader bounds checks, the next tags are likely to continue as patch-level hardening on the 8.18 line rather than open a new format frontier.
