fix(core): ignore canary and prerelease versions in update notifier (#11013) - #12747
In packages/docusaurus/bin/beforeCli.mjs, ignoreUpdate previously only checked whether update?.current started with 0.0.0 (update?.current?.startsWith('0.0.0')).
Historically, canary releases had versions prefixed with 0.0.0 (see #5378). However, Docusaurus subsequently adopted versioned canary tags matching coreVersion-canary-count+commit (e.g. 3.7.0-canary-6264). Because semver treats prerelease versions like 3.7.0-canary-6264 as having lower precedence than the stable release 3.7.0 (semver.lt('3.7.0-canary-6264', '3.7.0') === true), developers running modern canary releases or prereleases receive false-positive update notifications recommending they "upgrade" to the older stable release.
This PR updates ignoreUpdate to check whether update.current starts with 0.0.0, includes canary, or is identified as a prerelease by semver.prerelease(current). It also exports ignoreUpdate for direct unit testing.
Test Plan
Added unit tests in packages/docusaurus/bin/__tests__/beforeCli.test.ts testing:
I noticed modern canary installations (e.g. 3.7.0-canary-...) trigger a false-positive update notification recommending an upgrade to the older stable release because ignoreUpdate only checked

Walkthrough
The update notification logic uses an exported ignoreUpdate helper. It ignores 0.0.0 builds, canary versions, and semver prereleases. Tests cover notification behavior and minimum-Node-version validation.

ignoreUpdate is exported and ignores 0.0.0 builds, canary versions, and semver prereleases. beforeCli uses the helper to control notification output. Tests cover missing update data, stable versions, suppressed notifications, and minimum-Node-version validation.

Explanation
The title names the fix (ignoring canary and prerelease versions in the update notifier), which matches the main change in beforeCli.mjs. The changeset adds an exported ignoreUpdate helper that skips 0.0.0, canary, and semver prerelease versions, plus tests for those cases. The title also cites issue #11013, which the linked issue confirms. The PR objectives cite a different PR number (#12747), but the title and changeset agree on the change itself.
Full details: Linked Issues check
Explanation
Issue #11013 requires no update banner for canary versions such as 3.7.0-canary-6264. ignoreUpdate suppresses updates for version strings containing canary. It also preserves the legacy 0.0.0 check and suppresses semantic prereleases. Tests cover versioned canaries, legacy canaries, prereleases, stable updates, and the notification control flow. The issue's proposed version bump is not required because its expected behavior is no upgrade recommendation.

Explanation
The changes stay within issue #11013. The exported ignoreUpdate helper enables direct tests. The added tests verify notifier behavior and preserve stable notifications and Node.js validation. No unrelated production or test changes are shown.

Root Cause: Docusaurus previously tagged canaries as 0.0.0-xxxx, and ignoreUpdate in packages/docusaurus/bin/beforeCli.mjs only checked update?.current?.startsWith('0.0.0'). Since canaries migrated to versioned tags like 3.7.0-canary-6264, semver evaluates 3.7.0-canary-6264 < 3.7.0. Consequently, developers running canary or prerelease builds get prompted on every single CLI run to "upgrade" back to the older stable release.
2. Targeted & Non-Breaking Fix
Changes in production code: Only packages/docusaurus/bin/beforeCli.mjs is modified (+18 / -10 lines).
ignoreUpdate now safely returns true if:
update.current starts with 0.0.0 (legacy canaries)
update.current includes canary (current versioned canaries, e.g. 3.7.0-canary-6264)
semver.prerelease(update.current) is truthy (alpha, beta, rc prereleases)
Returns false if update or update.current is missing, ensuring genuine stable updates (e.g. 3.6.0 -> 3.7.0) continue to be notified without suppression.
3. Complete Test Coverage
Added dedicated unit tests in packages/docusaurus/bin/__tests__/beforeCli.test.ts (+85 lines) covering:
When ignoreUpdate(notifier.update) returns true (e.g. for Canary or prerelease builds), wrap the update notification display instead of returning early from beforeCli().
This ensures that the update notification is suppressed as intended while preserving the minimum Node.js version verification for all installations.

Initialize mockNotifierConfig and mockState using vi.hoisted() so that shared mock objects are defined before Vitest hoists and executes the vi.mock('update-notifier') factory.
Signed-off-by: Hardik Kaurani <hardikkaurani1@gmail.com>
Following the automated review feedback, I have completed two focused refinements:
Control-Flow Preservation (8d44563f8c): Replaced the early return; when suppressing canary/prerelease updates with if (!ignoreUpdate(notifier.update)) { ... } wrapping only the update banner. This preserves the minimum Node.js runtime validation check (semver.satisfies(process.version, requiredVersion)) across all installations.
Vitest Mock Hoisting (ce96b5bd60): Initialized mockNotifierConfig and mockState using vi.hoisted(...) in packages/docusaurus/bin/__tests__/beforeCli.test.ts so shared mock instances are defined before Vitest executes the hoisted vi.mock('update-notifier') factory.
All 10 unit test cases in beforeCli.test.ts pass cleanly, formatting (oxfmt) and linting (eslint) checks report 0 errors, and all monorepo packages build successfully.
The PR is fully verified and ready for your review. Thank you!
