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 is two months post-launch and in active stabilization, shipping White Label alongside a steady stream of bug fixes.

Spectra Blocks launched in July 2026 as a WordPress blocks plugin with a companion Pro tier, and has been in post-launch stabilization since — the last 10 entries span version 1.0.1 through 1.0.7, covering the first two months. Bug fixes dominate, but two usability additions stand out: White Label support (both free and Pro, shipped simultaneously in the most recent release) and theme/style guide color sync. WordPress 7.1 compatibility ships in the latest release, keeping pace with the platform.

Pencil2D's 0.7.1 candidates are mostly about not losing the user's work

◆ 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 Blocks is two months post-launch and in active stabilization, shipping White Label alongside a steady stream of bug fixes.

◆ Current state

Spectra Blocks launched in July 2026 as a WordPress blocks plugin with a companion Pro tier, and has been in post-launch stabilization since — the last 10 entries span version 1.0.1 through 1.0.7, covering the first two months. Bug fixes dominate, but two usability additions stand out: White Label support (both free and Pro, shipped simultaneously in the most recent release) and theme/style guide color sync. WordPress 7.1 compatibility ships in the latest release, keeping pace with the platform.

◆ Where it's heading

The frequent small-fix cadence with occasional feature drops is standard early-release behavior for a WordPress plugin team processing launch feedback. White Label signals an agency adoption play — resellers need to present tools as their own to clients, and adding that in version 1.0.x means it was likely a pre-launch customer request. The parallel Pro tier cadence tracking the free version closely points to an active freemium upgrade path being built.

◆ Prediction

The stabilization phase likely wraps with the 1.0.x series; the next move is probably a feature expansion cycle — new block types, deeper Style Guide integration, or marketing templates — based on what's resonating with the early user base.
