Release notes

1.0.0 — Initial release

Released on 20 September 2026 through the authenticated Nebula Composer repository.

• The nebula/admin metapackage installs the backend theme and 26 modules, including UI Bridge.

• Nineteen skins support light and dark modes. Compiled CSS and JavaScript ship with the packages.

Compatibility	Supported
Magento Open Source	2.4.9 framework line (magento/framework ~103.0.9)
MageOS	Compatible releases; application verification used 3.5.0
PHP	8.3, 8.4 and 8.5, subject to the platform matrix

Installation

Complete the free Nebula purchase to receive your Composer key, then follow Install to configure repository authentication and install nebula/admin:1.0.0. Keep minimum-stability: stable and commit the application's Composer lockfile.

All 28 package repositories have a 1.0.0 tag matching the released source. Each module carries its own changelog; the metapackage itself installs no files.

Verification

The release passed 2,604 Admin unit tests and 144 UI Bridge unit tests on each of PHP 8.3, 8.4 and 8.5, plus JavaScript typechecking and tests. A fresh Composer installation resolved all 28 Nebula packages at 1.0.0 and registered the 26 modules and backend theme. Magento DI compilation and validation of 200 Nebula definitions passed on the existing MageOS test installation.

Third-party extensions still need their own staging verification. See Known limitations and Upgrade, opt out, remove.
