Version 0.1.5

A faster, more expressive Codex workflow

  • 01

    Supports both legacy Codex renderers and Codex 26.727's new main-content structure, restoring theme injection, verification, and automatic re-application.

  • 02

    Restores background images on the new main-content surface while keeping avatar overlays and other auxiliary renderer targets excluded.

  • 03

    Improves current Codex process detection, preserves the .codextheme schema and saved window effects, and includes the latest Electric edge and pixel-cat refinements.

Verified release, not notarized

Both DMGs passed architecture, ad-hoc signature, mounted-content, and public-download checks. They are not Apple-notarized, so macOS Gatekeeper may show a security notice on first open.
