Processing vs TAO Testing: at a glance
What is Processing?
Processing is shipping again — and quietly moved its renderer onto wgpu.
Processing spent much of 2025 with a stalled release train; 4.5.4 in June explicitly marked the restart, and three releases have landed since. The work splits in two: build and release plumbing (the Ant-to-Gradle migration now sitting on Gradle 9.x, a release workflow that survives a failed macOS notarization) and an editor-shell refresh built on Jetpack Compose and Material 3. Contributor volume is the other signal — most release notes are lists of first-time PRs rather than maintainer work.
What is TAO Testing?
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.

Processing
3.8EDTECH
Processing is shipping again — and quietly moved its renderer onto wgpu.
◆ Current state
Processing spent much of 2025 with a stalled release train; 4.5.4 in June explicitly marked the restart, and three releases have landed since. The work splits in two: build and release plumbing (the Ant-to-Gradle migration now sitting on Gradle 9.x, a release workflow that survives a failed macOS notarization) and an editor-shell refresh built on Jetpack Compose and Material 3. Contributor volume is the other signal — most release notes are lists of first-time PRs rather than maintainer work.
◆ Where it's heading
The plumbing work is close to finished, which frees attention for the graphics stack. `the-wgpu-moment`, a branch open for nearly a year, is now merged into main, pointing Processing away from Java plus OpenGL through JOGL. Expect the next stretch to be about making that path usable and testable rather than about the editor UI.
◆ Prediction
The likely next move is exposing the wgpu renderer behind an opt-in flag with an open call for testers, while the 4.5.x line continues as the stable Gradle and Compose track.
TAO Testing
5.0EDTECH
TAO opens the 56.15 line with a database index while patching a bad migration on three branches.
◆ Current state
TAO's core cut 56.15.0, whose only listed change adds a database index for ReadonlyLiteral properties. On the same day it shipped 56.14.11, 56.14.8.1 and 56.13.1.3, each deprecating a bad migration on its branch. Earlier October releases were single-fix 56.14 patches on Resource Manager and task logging.
◆ Where it's heading
The project is still in maintenance mode ahead of its 2026-11 LTS, and the migration fix backported to three branches shows it supports several release lines at once. Opening 56.15 with a performance index instead of features suggests the LTS may be cut from the new line.
◆ Prediction
Expect more single-fix patches across 56.13–56.15 and then the November LTS. The entries don't show which line the LTS will be based on.
