Release notes

Sourced from i18next's releases.

v26.2.0

  • feat(types): new parseInterpolation TypeOption (default true). When set to false in CustomTypeOptions, the type-level extractor stops parsing translation strings for {{variable}} patterns. Required by i18next-icu users — the default extractor mistakes ICU MessageFormat nested-brace plurals like {count, plural, one {{count} row} other {{count} rows}} for an interpolation block and demands a phantom variable name. The flag is type-only; runtime interpolation is governed by InterpolationOptions and is unaffected. Fixes i18next-icu#85.
  • fix(types): expose enableSelector on InitOptions so i18next.init({ enableSelector: 'strict' }) typechecks without a module augmentation. The runtime already reads opts?.enableSelector from init options; this lands the matching type declaration next to the other selector-resolution knobs. Accepts false | true | 'optimize' | 'strict'. Thanks @​Faithfinder (#2431)

v26.1.0

  • feat: enableSelector: 'strict' (TypeOptions + runtime option). Opt-in mode that drops the flattened-primary form from NsResource at the type level — every namespace (primary included) is exposed only under its own key on $, uniformly across single- and multi-ns hooks. At runtime, a leading selector path segment matching the scope's namespace list is always rewritten as a namespace prefix, including the primary. Eliminates the silent-miss surface area where t($ => $.primary.foo) typechecks but doesn't resolve under the default mode (see #2429). Backward-compatible: default enableSelector: false | true | 'optimize' behavior is unchanged. Note: strict mode is incompatible with the #2405 pattern (keys whose names match sibling namespaces) — those users should stay on default mode.

v26.0.10

  • feat: getFixedT accepts a fourth optional fixedOpts argument carrying scopeNs — the full namespace list the bound t was created for. The selector API uses scopeNs to detect when a path's first segment is a namespace prefix, without changing resolution scope. Resolution still uses the bound ns (a single primary string in the typical react-i18next setup), so plain t('key') lookups stay isolated to the primary namespace exactly as before — only t($ => $.secondaryNs.foo) selectors now route correctly under useTranslation([nsA, nsB]). Fixes the runtime side of #2429 for the react-i18next default-nsMode case. The 4th argument is opt-in: existing 3-arg getFixedT(lng, ns, keyPrefix) callers see no behavior change.

v26.0.9

  • fix(types): unformatted interpolation values are now typed as string | number (was string). i18next stringifies values at runtime, so requiring callers to wrap numbers in String(...) for plain {{var}} placeholders was unnecessary friction — and could mask the real problem when a non-string value was passed alongside multiple interpolation slots (the t() overload resolution would fall through to the 3-arg form and report a confusing "not assignable to string" error against the options object). Typed format specifiers like {{x, number}}, {{x, currency}}, {{x, datetime}}, etc. keep their precise types; this only relaxes the no-format default. The count variable remains number-only

v26.0.8

  • fix(types): restore the pre-v25.10.4 ExistsFunction shape so plain arrow functions can again be assigned to ExistsFunction-typed variables (TypeScript cannot infer type predicates through multi-overload assignment). Direct i18next.exists(key) calls still narrow key to SelectorKey — the predicate is now declared inline on i18n.exists. Custom wrappers that want the narrowing can type themselves as typeof i18next.exists 2425

v26.0.7

  • fix: when a plural lookup misses, the missingKey debug log now shows the actual plural-resolved key (e.g. foo.bar_many for Polish count: 14) instead of the base key — making it obvious which plural category was expected and missing 2423
  • chore: drop @babel/runtime runtime dependency. The build no longer generates any @babel/runtime imports, so the package is unused by consumers. Rollup now uses babelHelpers: 'bundled' so any helpers that are ever needed in the future will be inlined rather than imported externally 2424
  • chore: stop emitting dist/esm/i18next.bundled.js. It was byte-identical to dist/esm/i18next.js because no helpers were being imported 2424

v26.0.6

Security release — all issues found via an internal audit. GHSA advisory filed after release.

  • security: warn when a translation string combines escapeValue: false with interpolated variables inside a $t(key, { ... "{{var}}" ... }) nesting-options block. In that narrow combination, attacker-controlled string values containing " can break out of the JSON options literal and inject additional nesting options (e.g. redirect lng/ns). The default escapeValue: true configuration is unaffected because HTML-escaping neutralises the quote before JSON.parse. See the security docs for mitigation guidance (GHSA-TBD)
  • security: apply regexEscape to unescapePrefix / unescapeSuffix on par with the other interpolation delimiters. Prevents ReDoS (catastrophic-backtracking) when a misconfigured delimiter contains regex metacharacters, and fixes silent breakage of the {{- var}} syntax when the delimiter contains characters like (, [, .
  • security: strip CR/LF/NUL and other C0/C1 control characters from string log arguments to prevent log forging via user-controlled translation keys, language codes, namespaces, or interpolation variable names (CWE-117)
  • chore: ignore .env* and *.pem/*.key files in .gitignore

v26.0.5

  • fix: cloneInstance().changeLanguage() no longer fails to update language state when the target language is not yet loaded — a race between init()'s deferred load() and the user's changeLanguage() could overwrite isLanguageChangingTo, causing setLngProps to be skipped 2422

v26.0.4

  • fix(types): inline formatting options like {{price, currency(EUR)}} are now correctly resolved to their base format type (e.g. number for currency) instead of falling back to string 2378

v26.0.3

  • fix(types): addResourceBundle now accepts an optional 6th options parameter ({ silent?: boolean; skipCopy?: boolean }) matching the runtime API 2419

v26.0.2

  • fix(types): t("key", {} as TOptions) no longer produces a type error — the context constraint now bypasses strict checking when context is unknown (e.g. from TOptions) 2418

v26.0.1

  • fix: Formatter no longer crashes when alwaysFormat is true and no format specifier is present (format is undefined)
  • fix: Formatter now returns undefined/null values as-is instead of producing NaN when the value is missing

v26.0.0

This is a major breaking release:

Updates react-i18next from 15.7.4 to 17.0.8

Changelog

Sourced from react-i18next's changelog.

17.0.8

  • fix(types): <Trans i18nKey={$ => ...}> now typechecks under enableSelector: 'strict'. The Trans component's conditional type was gated on _EnableSelector extends true | 'optimize', excluding 'strict' and falling back to the legacy string-key signature. Runtime was already correct (it calls keyFromSelector(i18nKey) whenever typeof i18nKey === 'function'); this is a type-only fix that widens the conditional to include 'strict'. Thanks @​Faithfinder (#1921)

17.0.7

  • feat: useTranslation([nsA, nsB, ...]) now passes its full namespace list to getFixedT via the new scopeNs opt (requires i18next ≥ v26.0.10). This makes selector calls with a secondary-namespace prefix resolve correctly under default nsMode: t($ => $.nsB.foo) previously missed silently because the bound ns was the primary string only and i18next's selector rewrite needed an array. Resolution semantics are unchanged — plain t('key') lookups still stay isolated to the primary namespace by default; use nsMode: 'fallback' to opt into multi-ns fallback resolution as before. Fixes i18next#2429 for useTranslation-based callers.

17.0.6

  • fix: restore the v17 nodesToString output format consumed by i18next-cli's extractor while still rendering 1919 correctly
    • 17.0.5 fixed 1919 by changing what nodesToString produced, which inadvertently changed the extracted translation strings for keep-tags wrapping non-keep React elements
    • The fix now lives in the renderer: indexed <N> placeholders nested inside a keep-tag are scoped to that tag's own original React children (matching kept tags by name and positional occurrence at each level), so the translation string format produced by nodesToString is unchanged

17.0.5

  • fix: <Trans /> no longer breaks child rendering when a kept HTML node (transKeepBasicHtmlNodesFor) wraps a non-keep React element 1919 — superseded by 17.0.6, which keeps the same runtime fix without changing the nodesToString output

17.0.4

  • fix: avoid React does not recognize the 'i18nIsDynamicList' prop on a DOM element warning 1915

17.0.3

  • fix: avoid invalid prop on React.Fragment inside <Trans /> 1914

17.0.2

  • fix(types): values prop on <Trans /> now only requires interpolation variables for the specific i18nKey, not all variables in the namespace 1913

17.0.1

  • chore: bump minimum i18next peer dependency to >= 26.0.1 (forgot to do it in last version)
  • fix: migrate test setup from removed legacy interpolation.format to i18n.services.formatter.add() (i18next v26)

17.0.0

Potentially breaking changes

  • fix: transKeepBasicHtmlNodesFor now correctly preserves HTML tag names when children contain interpolations or mixed content 230
    • Previously, <strong>{{name}}</strong> was incorrectly serialized as <1>{{name}}</1> — the tag name was only preserved for plain string children
    • This bug existed since the feature was introduced and affects auto-generated keys (when no explicit i18nKey is provided)
    • If you rely on auto-generated Trans keys containing indexed tags for kept HTML elements with interpolation children, you will need to update your translation files

Other changes

  • updated dev dependencies (vitest, rollup plugins, happy-dom, typescript, etc.)

Updates @types/react-dom from 19.2.3 to 18.3.7

Commits

Updates jsdom from 26.1.0 to 29.1.1

Release notes

Sourced from jsdom's releases.

v29.1.1

  • Fixed 'border-radius' computed style serialization. (@​asamuzaK)
  • Fixed computed style computation when using 'background-origin' and 'background-clip' CSS properties. (@​asamuzaK)
  • Significantly optimized initial calls to getComputedStyle(), before the cache warms up. (@​asamuzaK)

v29.1.0

  • Added basic support for the ratio CSS type. (@​asamuzaK)
  • Fixed getComputedStyle() sometimes returning outdated results after CSS was modified. (@​asamuzaK)

v29.0.2

  • Significantly improved and sped up getComputedStyle(). Computed value rules are now applied across a broader set of properties, and include fixes related to inheritance, defaulting keywords, custom properties, and color-related values such as currentcolor and system colors. (@​asamuzaK)
  • Fixed CSS 'background' and 'border' shorthand parsing. (@​asamuzaK)

v29.0.1

  • Fixed CSS parsing of 'border', 'background', and their sub-shorthands containing keywords or var(). (@​asamuzaK)
  • Fixed getComputedStyle() to return a more functional CSSStyleDeclaration object, including indexed access support, which regressed in v29.0.0.

v29.0.0

Breaking changes:

  • Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).

Other changes:

  • Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
  • Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
  • Added cssMediaRule.matches and cssSupportsRule.matches getters.
  • Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
  • Added cssKeyframeRule.keyText getter/setter validation.
  • Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
  • Added styleSheet.ownerNode, styleSheet.href, and styleSheet.title.
  • Added bad port blocking per the fetch specification, preventing fetches to commonly-abused ports.
  • Improved Document initialization performance by lazily initializing the CSS selector engine, avoiding ~0.5 ms of overhead per Document. (@​thypon)
  • Fixed a memory leak when stylesheets were removed from the document.
  • Fixed CSSStyleDeclaration modifications to properly trigger custom element reactions.
  • Fixed nested @media rule parsing.
  • Fixed CSSStyleSheet's "disallow modification" flag not being checked in all mutation methods.
  • Fixed XMLHttpRequest's response getter returning parsed JSON during the LOADING state instead of null.
  • Fixed getComputedStyle() crashing in XHTML documents when stylesheets contained at-rules such as @page or @font-face.
  • Fixed a potential hang in synchronous XMLHttpRequest caused by a race condition with the worker thread's idle timeout.

v28.1.0

  • Added blob.text(), blob.arrayBuffer(), and blob.bytes() methods.
  • Improved getComputedStyle() to account for CSS specificity when multiple rules apply. (@​asamuzaK)
  • Improved synchronous XMLHttpRequest performance by using a persistent worker thread, avoiding ~400ms of setup overhead on every synchronous request after the first one.
  • Improved performance of node.getRootNode(), node.isConnected, and event.dispatchEvent() by caching the root node of document-connected trees.
  • Fixed getComputedStyle() to correctly handle !important priority. (@​asamuzaK)
  • Fixed document.getElementById() to return the first element in tree order when multiple elements share the same ID.
  • Fixed <svg> elements to no longer incorrectly proxy event handlers to the Window.
  • Fixed FileReader event timing and fileReader.result state to more closely follow the spec.

[4.3.0] - 2026-05-08

Added

  • Add @container-size utility (#18901)

  • Ensure query params in imports are considered unique resources when using @tailwindcss/webpack (#19723)
