Promoted rules

New rules are incubated in the nursery group.
Once stable, we promote them to a stable group.
The following rules are promoted:

• a11y/noAriaUnsupportedElements
• a11y/noNoninteractiveTabindex
• a11y/noRedundantRoles
• a11y/useValidAriaValues
• complexity/noBannedTypes
• complexity/noStaticOnlyClass
• complexity/noUselessEmptyExport
• complexity/noUselessThisAlias
• correctness/noConstantCondition
• correctness/noNonoctalDecimalEscape
• correctness/noSelfAssign
• style/useLiteralEnumMembers
• style/useNamingConvention
• suspicious/noControlCharactersInRegex
• suspicious/noUnsafeDeclarationMerging
• suspicious/useGetterReturn

New rules

• Add noConfusingVoidType rule. The rule reports the unusual use of the void type. Contributed by @shulandmimi

Removed rules

• Remove noConfusingArrow.

  Code formatters, such as prettier and Biome, always adds parentheses around the parameter or the body of an arrow function.
  This makes the rule useless.

  Contributed by @Conaclos

Enhancements

• noFallthroughSwitchClause now relies on control flow analysis to report most of switch clause fallthrough. Contributed by @Conaclos

• noAssignInExpressions no longer suggests code fixes. Most of the time the suggestion didn't match users' expectations. Contributed by @Conaclos

• noUselessConstructor no longer emits safe code fixes. Contributed by @Conaclos

  All code fixes are now emitted as unsafe code fixes.
  Removing a constructor can change the behavior of a program.

• useCollapsedElseIf now only provides safe code fixes. Contributed by @Conaclos

• noUnusedVariables now reports more cases.

  The rule is now able to ignore self-writes.
  For example, the rule reports the following unused variable:

  let a = 0;
  a++;
  a += 1;

  The rule is also capable of detecting an unused declaration that uses itself.
  For example, the rule reports the following unused interface:

  interface I {
    instance(): I
  }

  Finally, the rule now ignores all TypeScript declaration files,
  including global declaration files.

Bug fixes

• Fix #182, making useLiteralKeys retains optional chaining. Contributed by @denbezrukov

• Fix #168, fix useExhaustiveDependencies false positive case when stable hook is on a new line. Contributed by @denbezrukov

• Fix #137, fix noRedeclare false positive case with TypeScript module declaration:

  declare module '*.gif' {
      const src: string;
  }
  
  declare module '*.bmp' {
      const src: string;
  }

  Contributed by @denbezrukov

• Fix #258, fix noUselessFragments the case where the rule removing an assignment. Contributed by @denbezrukov

• Fix #266, where complexity/useLiteralKeys emitted a code action with an invalid AST. Contributed by @ematipico

• Fix #105, removing false positives reported by noUnusedVariables.

  The rule no longer reports the following used variable:

  const a = f(() => a);

  Contributed by @Conaclos

VSCode

Enhancements

• Improve server binary resolution when using certain package managers, notably pnpm.

  The new strategy is to point to node_modules/.bin/biome path,
  which is consistent for all package managers.
