Summary

CSS Nesting Module Level 1 permits & as a <subclass-selector>, meaning it can appear after a type selector (e.g. h1& { color: red; }). Previously SubSelectorList::START_SET did not include T![&], causing a parse error.

Changes

css.ungram: added CssNestedSelector to AnyCssSubSelector
nodes.rs: regenerated via cargo run -p xtask_codegen -- grammar css
nested_selector.rs: added parse_nested_selector_as_sub_selector (bare & only, no SCSS suffix)
mod.rs: added T![&] to SubSelectorList::START_SET; dispatch in parse_sub_selector
specificity.rs: CssNestedSelector → ZERO_SPECIFICITY (consistent with leading &)
sub_selector.rs: new match arm (regenerated via cargo run -p xtask_codegen -- formatter)
Test: ok/nesting/trailing_amp.css + accepted snapshot

Walkthrough

The CSS grammar now accepts CssNestedSelector in sub-selector positions, including trailing & forms. The parser adds parse_nested_selector_as_sub_selector and updates parse_sub_selector dispatch. The formatter and specificity evaluator now handle the new variant. A test fixture and changeset entry were added.

Thank you!

…tors Fixes biomejs#7718. CSS Nesting Module Level 1 specifies that `&` (nesting selector) is a valid <subclass-selector> and can appear after a type selector, e.g. `h1& { ... }`. Previously SubSelectorList::START_SET did not include T![&], so the parser stopped at `&` after `h1` and emitted a parse error. Changes: - css.ungram: add CssNestedSelector to AnyCssSubSelector - generated nodes.rs: regenerated via `cargo run -p xtask_codegen -- grammar css` - nested_selector.rs: add parse_nested_selector_as_sub_selector (bare &, no SCSS suffix) for use in sub-selector position - mod.rs: add T![&] to SubSelectorList::START_SET and dispatch to parse_nested_selector_as_sub_selector in parse_sub_selector - specificity.rs: add CssNestedSelector arm (ZERO_SPECIFICITY, consistent with how the leading & is treated) - sub_selector.rs: add CssNestedSelector arm (regenerated via `cargo run -p xtask_codegen -- formatter`) - add test fixture ok/nesting/trailing_amp.css with snapshot Note: This PR was written primarily by Claude Code.

Now the rule [`useValidAutocomplete`](https://biomejs.dev/linter/rules/use-valid-autocomplete/) correctly flags the `autoComplete` attribute. - [#10796](biomejs/biome#10796) [`f1b3ab2`](biomejs/biome@f1b3ab2) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#10768](biomejs/biome#10768). Improved the performance of the Biome Language Server by cancelling certain in-flight operations when there are fast updates. - [#10719](biomejs/biome#10719) [`aa649b5`](biomejs/biome@aa649b5) Thanks [@minseong0324](https://github.com/minseong0324)! - Fixed [`noMisleadingReturnType`](https://biomejs.dev/linter/rules/no-misleading-return-type/) false positive on returns that use a widening type assertion: `"a" as string` is no longer reported as misleading. The rule now also reports a literal-pinning assertion such as `false as false`, matching the existing `as const` behavior. ```ts // No longer flagged (returns are `string`): function getValue(b: boolean): string { if (b) return "a" as string; return "b" as string; } // Now also reported, like `as const` (returns `false`): function isReady(): boolean { return false as false; } ``` - [#10678](biomejs/biome#10678) [`8f073a7`](biomejs/biome@8f073a7) Thanks [@PranavAchar01](https://github.com/PranavAchar01)! - Fixed [#7718](biomejs/biome#7718): Biome now correctly parses CSS nesting selectors when `&` appears as a trailing sub-selector after a type selector, e.g. `h1& { color: red; }`. - [#10756](biomejs/biome#10756) [`5ec965a`](biomejs/biome@5ec965a) Thanks [@denbezrukov](https://github.com/denbezrukov)! - Fixed CSS formatter output for selector lists with `allowWrongLineComments` and `//` comments after a selector comma. Biome now keeps the selector before the line comment inline instead of breaking it across descendant combinators. ```diff -.powerPathNavigator - .helm - button.pressedButton, // pressed +.powerPathNavigator .helm button.pressedButton, // pressed .powerPathNavigator .helm button:active:not(.disabledButton) { } ``` - [#10757](biomejs/biome#10757) [`6232fcd`](biomejs/biome@6232fcd) Thanks [@PranavAchar01](https://github.com/PranavAchar01)! - Fixed [#8269](biomejs/biome#8269): the CSS parser now accepts Tailwind `@variant` and `@utility` names that start with a digit, such as the `2xl` breakpoint. ```css @utility container { @variant 2xl { max-width: 1400px; } } ``` - [#10777](biomejs/biome#10777) [`575ced6`](biomejs/biome@575ced6) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): the GitLab reporter now handles `--verbose` diagnostics filtering correctly. - [#10281](biomejs/biome#10281) [`0efe244`](biomejs/biome@0efe244) Thanks [@Zelys-DFKH](https://github.com/Zelys-DFKH)! - Fixed a bug where GritQL patterns rejected positional (unkeyed) arguments. - [#10758](biomejs/biome#10758) [`e36fd8a`](biomejs/biome@e36fd8a) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10697](biomejs/biome#10697): The formatter no longer removes the parentheses around an `await` or `yield` expression used as the target of a TypeScript instantiation expression. For example, `(await makeFactory)<Value>` is no longer reformatted to `await makeFactory<Value>`, which would change the meaning of the code. - [#10586](biomejs/biome#10586) [`3617094`](biomejs/biome@3617094) Thanks [@IxxyDev](https://github.com/IxxyDev)! - Fixed [#9568](biomejs/biome#9568): [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) no longer reports a false positive when calling an overloaded function and the selected overload does not return a promise. ```ts function bestEffort(cb: () => Promise<number>): Promise<number>; function bestEffort(cb: () => number): number; function bestEffort( cb: () => number | Promise<number>, ): Promise<number> | number { return cb() as Promise<number> | number; } // This resolves to the second overload, which returns `number`, so it is no // longer flagged as a floating promise. bestEffort(() => 42); ``` - [#10766](biomejs/biome#10766) [`7aff4c1`](biomejs/biome@7aff4c1) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#2862](biomejs/biome#2862): [`noInteractiveElementToNoninteractiveRole`](https://biomejs.dev/linter/rules/no-interactive-element-to-noninteractive-role/) no longer reports custom elements (a tag name containing a dash, e.g. `<my-button role="img" />`). Per the [W3C HTML-ARIA specification](https://www.w3.org/TR/html-aria/#el-autonomous-custom-element), a custom element may be given any role or none. - [#10680](biomejs/biome#10680) [`771daa4`](biomejs/biome@771daa4) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed [#10635](biomejs/biome#10635): Biome now recognizes chained table tests such as `test.concurrent.each()` and `it.concurrent.each()` as test calls, fixing `noMisplacedAssertion` false positives and improving formatting for those test declarations. - [#10759](biomejs/biome#10759) [`34570b5`](biomejs/biome@34570b5) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10636](biomejs/biome#10636): [noStaticElementInteractions](https://biomejs.dev/linter/rules/no-static-element-interactions/) no longer reports a false positive for event handlers on Svelte special elements such as `<svelte:window>`, `<svelte:document>`, and `<svelte:body>`. These are not real DOM elements, so they are now ignored by the rule. - [#10741](biomejs/biome#10741) [`bd2364e`](biomejs/biome@bd2364e) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#6686](biomejs/biome#6686): the `rage` command now respects the `--config-path` option and the `BIOME_CONFIG_PATH` environment variable when loading the Biome configuration. Previously it always used the default configuration resolution and reported the configuration as `Not set` when no `biome.json` existed in the working directory. - [#10763](biomejs/biome#10763) [`2c3e82d`](biomejs/biome@2c3e82d) Thanks [@Aqu1bp](https://github.com/Aqu1bp)! - Fixed [#10742](biomejs/biome#10742): [`noSolidDestructuredProps`](https://biomejs.dev/linter/rules/no-solid-destructured-props) now reports destructured props in Solid function components and JSX children. - [#10606](biomejs/biome#10606) [`a4cc4ab`](biomejs/biome@a4cc4ab) Thanks [@Mokto](https://github.com/Mokto)! - Fixed false positives in `noUnusedImports`, `noUnusedVariables`, and `useImportType` for Svelte components that use both a `<script module>` and a `<script>` block. The two blocks compile to a single module and share a top-level scope, so a binding (import, function, or variable) declared in one block and used only in the other is no longer reported as unused. - [#10767](biomejs/biome#10767) [`36d5aa7`](biomejs/biome@36d5aa7) Thanks [@otkrickey](https://github.com/otkrickey)! - Fixed [#10754](biomejs/biome#10754): [`useVueValidVBind`](https://biomejs.dev/linter/rules/use-vue-valid-v-bind/) no longer reports the Vue 3.4+ same-name shorthand as missing a value. `:foo` and `v-bind:foo` are now accepted as equivalent to `:foo="foo"`, while `v-bind`, `v-bind:[dynamicArg]`, and `:[dynamicArg]` without a value continue to be reported. - [#10775](biomejs/biome#10775) [`a918af0`](biomejs/biome@a918af0) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): `biome rage` didn't detect running Biome daemon pipes on Windows. - [#10730](biomejs/biome#10730) [`5a2e65b`](biomejs/biome@5a2e65b) Thanks [@dinocosta](https://github.com/dinocosta)! - Fixed an issue where Biome was resolving [the well-known Zed settings file](https://biomejs.dev/guides/configure-biome/#well-known-files) from the wrong location on macOS and Windows. - [#10807](biomejs/biome#10807) [`d97fffe`](biomejs/biome@d97fffe) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where `.scss` files were incorrectly analyzed when running `biome check`. - [#10672](biomejs/biome#10672) [`53c6efc`](biomejs/biome@53c6efc) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a bug where Biome incorrectly formatted snippets that have parsing errors. - [#10719](biomejs/biome#10719) [`aa649b5`](biomejs/biome@aa649b5) Thanks [@minseong0324](https://github.com/minseong0324)! - Fixed [`useAwaitThenable`](https://biomejs.dev/linter/rules/use-await-thenable/) false positive when awaiting a custom thenable that is not the global `Promise`. A value with a callable `then` member is now recognized as awaitable. ```ts interface Thenable<T> { then(onfulfilled: (value: T) => void): void; } declare const t: Thenable<number>; async function f() { await t; } ``` - [#10734](biomejs/biome#10734) [`4396496`](biomejs/biome@4396496) Thanks [@BangDori](https://github.com/BangDori)! - Fixed [#10708](biomejs/biome#10708): `biome migrate` now preserves trivia when migrating the deprecated `recommended` option to `preset`. - [#10683](biomejs/biome#10683) [`ae31a00`](biomejs/biome@ae31a00) Thanks [@Netail](https://github.com/Netail)! - Fixed [#10657](biomejs/biome#10657) [#10671](biomejs/biome#10671) [#10661](biomejs/biome#10661) [#10637](biomejs/biome#10637) [#10718](biomejs/biome#10718): HTML rules now correctly handle dynamic attributes. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't correctly detect styles defined inside the Astro directive `is:global`. - [#10770](biomejs/biome#10770) [`dd1429c`](biomejs/biome@dd1429c) Thanks [@ematipico](https://github.com/ematipico)! - Improved the Biome Language Server DX by orchestrating certain operations, so that they won't block the editor during typing. This improvement is more visible in large documents. - [#10473](biomejs/biome#10473) [`d9b5133`](biomejs/biome@d9b5133) Thanks [@Mokto](https://github.com/Mokto)! - Improved [`noUnusedImports`](https://biomejs.dev/linter/rules/no-unused-imports/), [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/), [`noUnusedFunctionParameters`](https://biomejs.dev/linter/rules/no-unused-function-parameters/), and [`useImportType`](https://biomejs.dev/linter/rules/use-import-type/) for Svelte, Vue, and Astro files (with `html.experimentalFullSupportEnabled`). Bindings used only in the template — including component tags, attribute interpolations, directives, `bind:` shorthand, and snippet parameters — are no longer reported as unused, while genuinely unused ones still are. - [#10796](biomejs/biome#10796) [`f1b3ab2`](biomejs/biome@f1b3ab2) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where the Biome Language Server didn't enable project or type-aware lint rules, even when they were explicitly enabled. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't detect styles declared inside HTML documents. - [#10774](biomejs/biome#10774) [`bde945b`](biomejs/biome@bde945b) Thanks [@pattrickrice](https://github.com/pattrickrice)! - Fixed [#10268](biomejs/biome#10268) where a race condition resulted in internal errors such as: `The file biome.json does not exist in the workspace`. </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.

Biome now keeps the selector before the line comment inline instead of breaking it across descendant combinators. ```diff -.powerPathNavigator - .helm - button.pressedButton, // pressed +.powerPathNavigator .helm button.pressedButton, // pressed .powerPathNavigator .helm button:active:not(.disabledButton) { } ``` - [#10757](biomejs/biome#10757) [`6232fcd`](biomejs/biome@6232fcd) Thanks [@PranavAchar01](https://github.com/PranavAchar01)! - Fixed [#8269](biomejs/biome#8269): the CSS parser now accepts Tailwind `@variant` and `@utility` names that start with a digit, such as the `2xl` breakpoint. ```css @utility container { @variant 2xl { max-width: 1400px; } } ``` - [#10777](biomejs/biome#10777) [`575ced6`](biomejs/biome@575ced6) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): the GitLab reporter now handles `--verbose` diagnostics filtering correctly. - [#10281](biomejs/biome#10281) [`0efe244`](biomejs/biome@0efe244) Thanks [@Zelys-DFKH](https://github.com/Zelys-DFKH)! - Fixed a bug where GritQL patterns rejected positional (unkeyed) arguments. - [#10758](biomejs/biome#10758) [`e36fd8a`](biomejs/biome@e36fd8a) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10697](biomejs/biome#10697): The formatter no longer removes the parentheses around an `await` or `yield` expression used as the target of a TypeScript instantiation expression. For example, `(await makeFactory)<Value>` is no longer reformatted to `await makeFactory<Value>`, which would change the meaning of the code. - [#10586](biomejs/biome#10586) [`3617094`](biomejs/biome@3617094) Thanks [@IxxyDev](https://github.com/IxxyDev)! - Fixed [#9568](biomejs/biome#9568): [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) no longer reports a false positive when calling an overloaded function and the selected overload does not return a promise. ```ts function bestEffort(cb: () => Promise<number>): Promise<number>; function bestEffort(cb: () => number): number; function bestEffort( cb: () => number | Promise<number>, ): Promise<number> | number { return cb() as Promise<number> | number; } // This resolves to the second overload, which returns `number`, so it is no // longer flagged as a floating promise. bestEffort(() => 42); ``` - [#10766](biomejs/biome#10766) [`7aff4c1`](biomejs/biome@7aff4c1) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#2862](biomejs/biome#2862): [`noInteractiveElementToNoninteractiveRole`](https://biomejs.dev/linter/rules/no-interactive-element-to-noninteractive-role/) no longer reports custom elements (a tag name containing a dash, e.g. `<my-button role="img" />`). Per the [W3C HTML-ARIA specification](https://www.w3.org/TR/html-aria/#el-autonomous-custom-element), a custom element may be given any role or none. - [#10680](biomejs/biome#10680) [`771daa4`](biomejs/biome@771daa4) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed [#10635](biomejs/biome#10635): Biome now recognizes chained table tests such as `test.concurrent.each()` and `it.concurrent.each()` as test calls, fixing `noMisplacedAssertion` false positives and improving formatting for those test declarations. - [#10759](biomejs/biome#10759) [`34570b5`](biomejs/biome@34570b5) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10636](biomejs/biome#10636): [noStaticElementInteractions](https://biomejs.dev/linter/rules/no-static-element-interactions/) no longer reports a false positive for event handlers on Svelte special elements such as `<svelte:window>`, `<svelte:document>`, and `<svelte:body>`. These are not real DOM elements, so they are now ignored by the rule. - [#10741](biomejs/biome#10741) [`bd2364e`](biomejs/biome@bd2364e) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#6686](biomejs/biome#6686): the `rage` command now respects the `--config-path` option and the `BIOME_CONFIG_PATH` environment variable when loading the Biome configuration. Previously it always used the default configuration resolution and reported the configuration as `Not set` when no `biome.json` existed in the working directory. - [#10763](biomejs/biome#10763) [`2c3e82d`](biomejs/biome@2c3e82d) Thanks [@Aqu1bp](https://github.com/Aqu1bp)! - Fixed [#10742](biomejs/biome#10742): [`noSolidDestructuredProps`](https://biomejs.dev/linter/rules/no-solid-destructured-props) now reports destructured props in Solid function components and JSX children. - [#10606](biomejs/biome#10606) [`a4cc4ab`](biomejs/biome@a4cc4ab) Thanks [@Mokto](https://github.com/Mokto)! - Fixed false positives in `noUnusedImports`, `noUnusedVariables`, and `useImportType` for Svelte components that use both a `<script module>` and a `<script>` block. The two blocks compile to a single module and share a top-level scope, so a binding (import, function, or variable) declared in one block and used only in the other is no longer reported as unused. - [#10767](biomejs/biome#10767) [`36d5aa7`](biomejs/biome@36d5aa7) Thanks [@otkrickey](https://github.com/otkrickey)! - Fixed [#10754](biomejs/biome#10754): [`useVueValidVBind`](https://biomejs.dev/linter/rules/use-vue-valid-v-bind/) no longer reports the Vue 3.4+ same-name shorthand as missing a value. `:foo` and `v-bind:foo` are now accepted as equivalent to `:foo="foo"`, while `v-bind`, `v-bind:[dynamicArg]`, and `:[dynamicArg]` without a value continue to be reported. - [#10775](biomejs/biome#10775) [`a918af0`](biomejs/biome@a918af0) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): `biome rage` didn't detect running Biome daemon pipes on Windows. - [#10730](biomejs/biome#10730) [`5a2e65b`](biomejs/biome@5a2e65b) Thanks [@dinocosta](https://github.com/dinocosta)! - Fixed an issue where Biome was resolving [the well-known Zed settings file](https://biomejs.dev/guides/configure-biome/#well-known-files) from the wrong location on macOS and Windows. - [#10807](biomejs/biome#10807) [`d97fffe`](biomejs/biome@d97fffe) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where `.scss` files were incorrectly analyzed when running `biome check`. - [#10672](biomejs/biome#10672) [`53c6efc`](biomejs/biome@53c6efc) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a bug where Biome incorrectly formatted snippets that have parsing errors. - [#10719](biomejs/biome#10719) [`aa649b5`](biomejs/biome@aa649b5) Thanks [@minseong0324](https://github.com/minseong0324)! - Fixed [`useAwaitThenable`](https://biomejs.dev/linter/rules/use-await-thenable/) false positive when awaiting a custom thenable that is not the global `Promise`. A value with a callable `then` member is now recognized as awaitable. ```ts interface Thenable<T> { then(onfulfilled: (value: T) => void): void; } declare const t: Thenable<number>; async function f() { await t; } ``` - [#10734](biomejs/biome#10734) [`4396496`](biomejs/biome@4396496) Thanks [@BangDori](https://github.com/BangDori)! - Fixed [#10708](biomejs/biome#10708): `biome migrate` now preserves trivia when migrating the deprecated `recommended` option to `preset`. - [#10683](biomejs/biome#10683) [`ae31a00`](biomejs/biome@ae31a00) Thanks [@Netail](https://github.com/Netail)! - Fixed [#10657](biomejs/biome#10657) [#10671](biomejs/biome#10671) [#10661](biomejs/biome#10661) [#10637](biomejs/biome#10637) [#10718](biomejs/biome#10718): HTML rules now correctly handle dynamic attributes. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't correctly detect styles defined inside the Astro directive `is:global`. - [#10770](biomejs/biome#10770) [`dd1429c`](biomejs/biome@dd1429c) Thanks [@ematipico](https://github.com/ematipico)! - Improved the Biome Language Server DX by orchestrating certain operations, so that they won't block the editor during typing. This improvement is more visible in large documents. - [#10473](biomejs/biome#10473) [`d9b5133`](biomejs/biome@d9b5133) Thanks [@Mokto](https://github.com/Mokto)! - Improved [`noUnusedImports`](https://biomejs.dev/linter/rules/no-unused-imports/), [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/), [`noUnusedFunctionParameters`](https://biomejs.dev/linter/rules/no-unused-function-parameters/), and [`useImportType`](https://biomejs.dev/linter/rules/use-import-type/) for Svelte, Vue, and Astro files (with `html.experimentalFullSupportEnabled`). Bindings used only in the template — including component tags, attribute interpolations, directives, `bind:` shorthand, and snippet parameters — are no longer reported as unused, while genuinely unused ones still are. - [#10796](biomejs/biome#10796) [`f1b3ab2`](biomejs/biome@f1b3ab2) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where the Biome Language Server didn't enable project or type-aware lint rules, even when they were explicitly enabled. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't detect styles declared inside HTML documents. - [#10774](biomejs/biome#10774) [`bde945b`](biomejs/biome@bde945b) Thanks [@pattrickrice](https://github.com/pattrickrice)! - Fixed [#10268](biomejs/biome#10268) where a race condition resulted in internal errors such as: `The file biome.json does not exist in the workspace`. </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
