Astra vs Spectra: at a glance
What is Astra?
Astra's November 12 releases close two Pro security holes and fix menus for screen readers.
Astra stays on a two-week cadence of paired free and Pro releases, most of them fixes. Free 4.14.3 fixes submenu behavior for screen readers, touch and mouse users, a mobile header that appeared at the wrong breakpoint and Customizer saves over the REST API. Pro 4.13.13 closes a shortcode-injection path through search terms and stored scripts in Auto Load Previous Post, and fixes Modern Checkout and Germanized issues.
What is Spectra?
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
Astra vs Spectra: editorial side-by-side
Astra
5.0DESIGN
Astra's November 12 releases close two Pro security holes and fix menus for screen readers.
◆ Current state
Astra stays on a two-week cadence of paired free and Pro releases, most of them fixes. Free 4.14.3 fixes submenu behavior for screen readers, touch and mouse users, a mobile header that appeared at the wrong breakpoint and Customizer saves over the REST API. Pro 4.13.13 closes a shortcode-injection path through search terms and stored scripts in Auto Load Previous Post, and fixes Modern Checkout and Germanized issues.
◆ Where it's heading
The theme is in maintenance mode: security hardening, WooCommerce checkout repair and accessibility fixes, with the September custom Global Palette colors the last visible feature. Modern Checkout and Site Builder remain where most Pro issues and fixes land.
◆ Prediction
Expect another paired fix release in about two weeks, again led by Pro security and Modern Checkout fixes; nothing in the entries points to a new feature.
Spectra
5.0DESIGN
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
◆ Current state
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
◆ Where it's heading
After the AI page import push in September, releases have been about trust in the output: render it correctly, make it count for SEO, now make it fast and accessible. The Pro add-on follows the same cadence with design-token and dynamic-data fixes.
◆ Prediction
Expect accessibility passes on other interactive blocks such as tabs or accordions, following the Slider, alongside further Pro fix rounds.
