Pencil2D vs Spectra: at a glance
What is Pencil2D?
Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
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.

◆ Current state
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
◆ Where it's heading
For a hand-drawn animation tool the recurring subject is protecting in-progress work, and that is where these candidates spend their effort. The platform work sits alongside it: signed and notarized macOS builds and an updated Qt6 runner are the cost of shipping a desktop app users can install without warnings.
◆ Prediction
A general 0.7.1 release is the natural next step once the candidate cycle settles, though the twenty-month gap between candidates makes timing hard to call.
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.
