What is Oxygen?

Oxygen bolts an AI agent onto WordPress site-building, then irons out the betas.

Oxygen is a WordPress visual site builder that spent early 2026 on a v4 maintenance tail before jumping to the 6.x line. Version 6.1 delivered concrete builder gains — multi-element selection, variable fonts, conditional classes — and 6.2 made the headline move: connecting an AI agent to WordPress so it can build and edit pages, templates, and styles directly. The current work is beta-stabilizing that 6.2 release.

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.

Oxygen bolts an AI agent onto WordPress site-building, then irons out the betas.

◆ Current state

Oxygen is a WordPress visual site builder that spent early 2026 on a v4 maintenance tail before jumping to the 6.x line. Version 6.1 delivered concrete builder gains — multi-element selection, variable fonts, conditional classes — and 6.2 made the headline move: connecting an AI agent to WordPress so it can build and edit pages, templates, and styles directly. The current work is beta-stabilizing that 6.2 release.

◆ Where it's heading

The release rhythm is a disciplined beta to RC to stable grind, but the direction is set by one bet: turning the builder into an agent-operable surface. Oxygen shipped its AI-agent capability the same week as sibling builder Breakdance, and is now hardening it through 6.2 betas rather than chasing new UI features.

◆ Prediction

Expect more 6.2.x beta fixes to stabilize the agent integration, then a widening of which builder primitives the agent can touch as Oxygen races Breakdance and the wider WordPress-builder field to stay agent-addressable.

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.
