name: new-mantine-release description: Initialize a new Mantine minor or major release: creates a git branch, sets up the changelog MDX page, updates mdx-meta-data.ts, mdx-nav-data.ts, and versions.ts, and commits. Use when the user wants to start a new release (e.g., "new release 9.1.0", "/new-mantine-release 9.1.0", "initialize 9.2.0 release").

New Mantine Release

Set up everything needed to start a new release. The user provides the version (e.g., 9.1.0).

Notation

Given version X.Y.0:

• Branch name: X.Y (e.g., 9.1)
• Dashed version: X-Y-0 (e.g., 9-1-0)
• Key digits: version digits concatenated without dots (e.g., 910, 7170 for 7.17.0)
• Previous release date: the date field of the first entry in allVersions in packages/@mantinex/mantine-meta/src/versions.ts — used as the placeholder date

Steps

1. Create the git branch

git checkout -b X.Y
git config branch.X.Y.remote gitlab
git config branch.X.Y.merge refs/heads/X.Y

This creates branch X.Y and configures it to track the gitlab remote (not origin).

2. Read the previous release date

Read packages/@mantinex/mantine-meta/src/versions.ts and extract the date from the first entry in allVersions (e.g., 'May 26, 2026'). This is the placeholder date for the new release.

3. Create the MDX changelog file

Create apps/mantine.dev/src/pages/changelog/X-Y-0.mdx:

import { Layout } from '@/layout';
import { MDX_DATA } from '@/mdx';

export default Layout(MDX_DATA.ChangelogKEYDIGITS);

Replace KEYDIGITS with the key digits (e.g., Changelog910).

4. Add entry to mdx-meta-data.ts

Edit apps/mantine.dev/src/mdx/data/mdx-meta-data.ts. Insert a new changelog entry after the last existing Changelog* entry and before PreviousChangelogs.

Format (note ordinal suffix on date day: "1st", "2nd", "3rd", "4th"…"26th"):

  ChangelogKEYDIGITS: {
    title: 'Version vX.Y.0',
    slug: '/changelog/X-Y-0',
    release: 'https://github.com/mantinedev/mantine/releases/tag/X.Y.0',
    date: 'MONTH DAYth, YEAR',
    searchTags: 'X-Y-0, KEYDIGITS',
  },

Use the previous release date (with ordinal suffix on the day number) as the placeholder.

5. Add entry to mdx-nav-data.ts

Edit apps/mantine.dev/src/mdx/mdx-nav-data.ts. In the GETTING_STARTED_PAGES_GROUP, find the Changelog category and insert MDX_DATA.ChangelogKEYDIGITS as the first page in the pages array (before the existing first changelog entry, e.g., MDX_DATA.Changelog900).

6. Add entry to versions.ts

Edit packages/@mantinex/mantine-meta/src/versions.ts. Insert a new entry at the top of the allVersions array.

  {
    version: 'X.Y.0',
    date: 'PREVIOUS_RELEASE_DATE',
    github: 'https://github.com/mantinedev/mantine/releases/tag/X.Y.0',
    link: 'https://mantine.dev/changelog/X-Y-0',
    patches: [],
  },

7. Commit
