What is Astra?

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.

What is OpenImageIO?

Every image reader is now assumed hostile, and the fuzzer proves it monthly

OpenImageIO ships on a monthly rhythm, releasing the current 3.1 line and the explicitly obsolete 3.0 line in tandem within minutes of each other. The dominant work is defensive: guarding pnm, jpeg-xl, dicom, cineon, dpx, fits and iff readers against corrupt or hostile files, with a CVE fixed in cineon bit-depth validation and a new limits:resolution attribute capping per-dimension image size against decompression bombs. libFuzzer-based fuzzing infrastructure for format readers landed in August.

Astra vs OpenImageIO: editorial side-by-side

A
Astra
DESIGN
5.0

Two release trains, zero new features — Astra has been in pure maintenance mode since spring.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

O5.0

Every image reader is now assumed hostile, and the fuzzer proves it monthly

◆ Current state

OpenImageIO ships on a monthly rhythm, releasing the current 3.1 line and the explicitly obsolete 3.0 line in tandem within minutes of each other. The dominant work is defensive: guarding pnm, jpeg-xl, dicom, cineon, dpx, fits and iff readers against corrupt or hostile files, with a CVE fixed in cineon bit-depth validation and a new limits:resolution attribute capping per-dimension image size against decompression bombs. libFuzzer-based fuzzing infrastructure for format readers landed in August.

◆ Where it's heading

The project is institutionalizing the hardening rather than reacting to individual reports — building fuzzing into the repo, clarifying what qualifies as a vulnerability in its security policy, and adding a global attribute that lets applications set their own limits. Alongside that, oiiotool keeps gaining ergonomics, and genuinely new capability is being gated behind an explicit --experimental flag: the FLIP perceptual difference metric and a standalone GPU texture system prototype that deliberately does not touch the core library.

◆ Prediction

With 3.2 stated as roughly two months out and 3.0 support ending shortly after, expect the next releases to focus on that transition while the fuzzing infrastructure keeps producing reader fixes.
