Rotato changelog stops in 2023; last release is a crash-fix patch.
Rotato's published changelog goes quiet after August 2023 — the most recent release (142.378) is all crash fixes, preceded by 142.377's animation timeline and sidebar redesign. Earlier releases delivered a template gallery, 8K output, Figma plugin beta, and more device scenes. Whether the product is still shipping outside this changelog is unclear from the visible signal.
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.

From the entries shown, Rotato grew through 2021–2023 with steady scene additions, UI refinement, and ecosystem reach (Figma plugin) before the changelog went silent. The visible direction was toward higher-fidelity mockups and broader integration with designer tools, but there is no recent data to extend that line.
Without recent shipping data, predicting direction is unreliable. If shipping has actually stopped, the product is in maintenance mode; if shipping continues elsewhere, the public changelog is no longer where to look.
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.
This is an early-life product being hardened in public, and the choices reveal the audience. Version rollback is a safety net for agencies who update client sites and need an exit; theme colour sync is about blocks inheriting the site palette instead of fighting it. Both point at Spectra Blocks being positioned as infrastructure a professional builds on rather than a set of decorative blocks.
Expect the 1.0.x fix cadence to continue for several more weeks before the block library itself starts expanding, with Pro staying a release or two behind the free edition. The changelog bodies are truncated in this feed, so which specific blocks ship next is not visible from here.
