Release notes

Sourced from axios's releases.

v1.21.0 — October 21, 2026

This release adds response timing and opt-in UTF-8 Basic authentication, improves request handling across runtimes, and changes how header defaults are recognized.

⚠️ Breaking Changes & Deprecations

• Header Defaults: Only plain objects, null-prototype maps, and compatible AxiosHeaders instances are treated as common or method-specific defaults; literal headers such as Link are now preserved. Applications using custom class instances as defaults must convert them to plain maps, for example { post: { ...customDefaults } }, or compatible AxiosHeaders. Otherwise, those instances become literal header values, including on requests using other methods. (#11156)

🚀 New Features

• Response Timing: Added response.duration, in milliseconds, including on error.response when present. Timing measures adapter execution and excludes interceptors and transforms; streamed responses stop timing when the stream becomes available. Axios replaces any existing duration value supplied by a custom adapter. (#11214)
• UTF-8 Basic Authentication: Added transitional.encodeBasicAuthUsername: true to support Unicode usernames in XHR and Fetch requests. The option defaults to false, preserving existing authentication behavior; applications opting in should supply the original Unicode username and remove manual pre-encoding workarounds. (#11159)

🐛 Bug Fixes

• Fetch Compatibility: Restored requests in runtimes such as Cloudflare Workers that reject the implicit cache: 'default', while preserving explicit caller settings. Response-size failures now retain their original ERR_BAD_RESPONSE and request context when runtime wrappers replace the underlying stream error. (#11194, #11179)
• Runtime Consistency: Aligned encoded-byte size accounting, multipart uploads, proxy routing, same-origin resolution, parameter merging, and form serialization across adapters. Circular parameters now reject with ERR_BAD_OPTION_VALUE, and sparse or non-index numeric form fields serialize as keyed objects. With proxy: false, native proxyEnv agents using unsupported pool-management or TLS-session lifecycle overrides now reject with ERR_BAD_OPTION_VALUE; construct those agents without proxyEnv. (#11242)
• Header Handling: Preserved headers named __proto__ using safe casing without changing the AxiosHeaders instance prototype. Function matchers in has(), delete(), and clear() now receive the headers instance as this, matching their declared contract. (#11134, #11216)
• URL and Data URL Parsing: Accepted case-insensitive supported URL schemes and Base64 markers, and corrected decoding of percent-encoded Base64 data URLs. Node data URL allocation estimates remain aligned with decoding so configured size limits apply before allocation. (#11138, #11163, #11294)
• Error Diagnostics: Preserved short reconstructed request stacks and appended wrapped error stacks under Caused by: so tooling that reads only error.stack retains the original failure context. (#11132, #11142)
• Interceptor Removal: Restored removal through canonical numeric-string interceptor IDs, including after registry compaction. (#11139)
• Proxy TLS: HTTPS CONNECT tunnels now apply current origin TLS options from an explicit httpsAgent, or from https.globalAgent when no explicit agent is supplied. This preserves process-wide custom CA settings through proxy tunnels. (#11178)
• XHR Lifecycle: Used asynchronous Cookie Store reads for XSRF tokens where supported, preserving cookie fallback, timeout accounting, and cancellation. Upload and download progress listeners are now removed on completion, failure, timeout, and cancellation. (#11166, #11225)
• HTTP/2 Sessions: Stopped reusing sessions immediately after GOAWAY and prevented draining sessions from scheduling idle timers that could delay process exit. (#11210)
• TypeScript Declarations: Exposed the response-default marker as a public type to resolve TS2527 when consumers emit declarations involving unresolved response generics, covering both ESM and CommonJS. (#11125)

🔧 Maintenance & Chores

• Configuration Performance: Reduced request configuration merge overhead, particularly for requests with many headers, while preserving merge semantics and prototype-pollution guards. (#11208)
• Same-Origin Checks: Removed obsolete Internet Explorer detection without changing origin decisions in supported environments. (#11174)
• Dependencies: Updated follow-redirects to 1.16.1 and refreshed development, documentation, test, and GitHub Actions dependencies. Removed unused dayjs from the docs package, root chalk, and chai from CJS module tests. (#11169, #11188, #11189, #11195, #11212, #11213, #11218, #11220, #11221, #11230, #11234, #11244, #11245, #11266, #11267, #11268, #11269, #11270, #11271, #11272, #11298, #11302, #11303, #11304, #11305, #11306, #11313, #11321, #11322, #11323, #11342)
• Documentation: Fixed interceptor test links, updated README CDN examples to the published 1.20.0 bundle, and corrected guidance on interceptor options and request lifecycle ordering. (#11228, #11149, #11335)
• Contributor Workflow: Consolidated agent instructions in AGENTS.md, standardized PR labels, required prerelease notes and validation evidence, and clarified that npm test requires installed Playwright browsers. (#11238, #11273, #11223, #11284)
• Sponsors and Support: Added HeroDevs, Code for Japan, and Sweepico sponsor listings, refreshed sponsor data, and documented extended security support for Axios v0. (#11222, #11249, #11252, #11341)
• Proxy Regression Coverage: Added a long dotted request-hostname test for NO_PROXY handling, extending coverage of an existing denial-of-service fix. (#11235)
• Release Preparation: Updated package version metadata for 1.21.0. (#11346)

Updates i18next from 26.4.2 to 26.5.11

Release notes

Sourced from i18next's releases.

v26.5.11

• fix: a nested false, 0 or '' is now returned when a flat key with the same dotted name also exists. With { a: { b: false }, 'a.b': 'flat' }, getResource('en', 'translation', 'a.b') and t('a.b') returned 'flat': the nested result was checked for truthiness, so these present values fell through to the flat-key lookup. Without such a flat key they were already returned. A nested null, which is not a valid lookup by default (returnNull: false), still falls back to the flat key. Thanks @​lprnmns (#2461).

v26.5.10

• fix: when none of the detected languages is in supportedLngs, the best match no longer picks a different language whose code only starts with the same letters. The last fuzzy check took any supported code starting with the language part, so with supportedLngs: ['en', 'fil-PH'] a Finnish user (fi-FI) got Filipino instead of the fallback language, and ha (Hausa) picked haw-US (Hawaiian). Other regions of the same language still match as before (de-CH → de-DE, pt-PT → pt-BR, fil → fil-PH). Compatibility note: a two-letter code no longer matches a supported three-letter code that extends it, like ar → arz-EG, sw → swh-KE or no → nob-NO; list the two-letter code in supportedLngs (or map it with fallbackLng) if you relied on that. Thanks @​Pharex38 (#2460).

v26.5.9

• fix: nested lookups no longer resolve to methods inherited from the prototype, like constructor, toString or map. Only the top level was guarded, so {{constructor}} was treated as missing, but {{user.constructor}} rendered the function source (with a class instance, the full source code of the class), and {{user.toString}}, {{items.map}} or a class method like {{user.greet}} did the same. The same lookup is used for translation keys when ignoreJSONStructure is on (the default): a nested key named like an inherited method that is missing in the current language (t('roles.constructor') with roles.constructor only in the fallback language) returned function Object() { [native code] } instead of falling back, and exists('roles.valueOf') returned true. These keys are now missing, so the fallback language, missingInterpolationHandler, saveMissing and the missing key handler apply as for any other missing key. Getters defined on a class ({{user.fullName}} with get fullName()) still work. Nested lookups also no longer walk into the prototype via __proto__, so {{user.__proto__.constructor}} no longer prints the class source either. Thanks @​Pharex38 (#2459).

v26.5.8

• fix: arrays returned with joinArrays now get the same resolved details as strings. The joined value was extended with lastKey in the place of the resolved lookup, so with postProcessPassResolved a post processor got no usedLng, usedNS or exactUsedKey (t('steps', { joinArrays: ' / ' }) reported undefined/undefined:undefined). This affected the subliminal post processor used by the locize InContext editor, which could not map a joined array to its key. The nesting recursion guard did not get the parent key either, so arrays that nest each other (listA: ['a', '$t(listB)'], listB: ['b', '$t(listA)']) threw Maximum call stack size exceeded. They now stop at the guard, as strings do. An i18nFormat plugin with handleAsObject and parse also no longer throws Cannot read properties of undefined (reading 'usedNS') on joined arrays. Thanks @​nk-batman21 (#2458).

v26.5.7

• fix: with the default cacheInBuiltFormats: true, built-in formats now also work when the t() options contain a BigInt or a circular object. The cache key was built with JSON.stringify over all options, including the interpolation values, which throws on those, so every built-in format in that call returned the raw value: t('num', { val: 12345678901234567890n }) with 'Total: {{val, number}}' returned 'Total: 12345678901234567890' instead of 'Total: 12,345,678,901,234,567,890', and passing an object with a back-reference (like an ORM entity) left all numbers, dates and lists of that call unformatted. When the key cannot be built, the value is now formatted without the cache, as with cacheInBuiltFormats: false. This also applies to formatters added with addCached. Other calls still use the cache as before. Thanks @​nk-batman21 (#2457).

v26.5.6

• fix: cloneInstance({ forkResourceStore: true }) now copies the resources at every level. It copied them only down to the namespace objects, so nested keys and arrays stayed shared with the original instance: addResource() with a nested key (fork.addResource('en', 'translation', 'greeting.hello', 'Hi')) or a deep addResourceBundle() on the fork also changed the original instance and every other fork. Flat keys were already isolated. Forking a large store takes a bit longer: with 300k keys in nested groups, about 11 ms instead of 3 ms per fork. Clones without forkResourceStore still share the store as before. Thanks @​nk-batman21 (#2456, follow-up to #2270).

v26.5.5

• fix: with the default skipOnVariables: true, a {{placeholder}} inside a value inserted with an unescaped {{- var}} now stays literal, as it already did for {{var}}. The escape pass ran after the unescaped values were written and scanned them again, so t('{{- a}}', { a: '{{b}}', b: 'c' }) returned 'c' instead of '{{b}}'. With pre-built HTML that carries user text, like t('You may contact {{name}} at {{- emailHTML}}.', { name, emailHTML }), that text could pull another variable of the same t() call into the output. Results with skipOnVariables: false, and values without placeholders, are unchanged. Compatibility note: a {{- var}} value whose placeholders were meant to be filled from the same t() call now keeps them literally; skipOnVariables: false restores the old behavior. Thanks @​nk-batman21 (#2455, reported in #1595).

v26.5.4

• fix: with the default skipOnVariables: true, a {{placeholder}} inside an interpolated value now stays literal also when the same placeholder appears later in the translation. Each value was written with String.replace, which replaces the first copy of the placeholder text, and that could be the copy inside an earlier value: t('{{name}} has {{count}} items', { name: '{{count}}', count: 5 }) returned '5 has {{count}} items' instead of '{{count}} has 5 items'. The value is now written at the position of the matched placeholder. Results with skipOnVariables: false are unchanged. Thanks @​nk-batman21 (#2454, reported in #1595).
• fix: with useRawValueToEscape: true, a non-string value in an unescaped {{- var}} placeholder or with escapeValue: false no longer throws val.replace is not a function; it is converted to a string like any other value.

v26.5.3

• fix(types): with the selector API, a plural key now requires count also when the call passes an explicit ns. t(($) => $.item) already failed without count, but t(($) => $.item, { ns: 'items' }) compiled, although at runtime it looks up item instead of item_one / item_other and returns the key. It now fails the same way, also with ordinal: true, defaultValue, an ns array, a key prefix and i18n.t. Calls with count, context, returnObjects: true and arrays of selectors, as well as return types, are unchanged. Thanks @​nyarthan (#2452).

v26.5.2

• fix(types): on TypeScript 7, a t() call with a missing, misspelled or wrongly typed option now reports that option again (Property 'album' is missing, Type 'string' is not assignable to type 'number'), as TypeScript 5 and 6 do. TypeScript 7 elaborated the error against the default-value signature instead and ended in '{ count: 3; albm: "Summer"; }' is not assignable to type 'string': on a failed call TypeScript explains the last of the equally matching signatures, and TypeScript 7 sorts the 3-element [key, defaultValue, options?] last. It is now written as two signatures, [key, defaultValue] and [key, defaultValue, options]. This affects the default key checks with i18next {{name}} messages as well as parseInterpolation: 'icu' and 'mf2'. Which calls compile, their return types and the error positions are unchanged on TypeScript 5.9, 6 and 7.

v26.5.1

• perf(types): type-checking t() calls against a large namespace is no longer quadratic in the number of keys. TypeScript does not cache keyof of an object type, and the types rebuilt the union of all keys of a namespace once per key while building the key union, and again in every t() call to look up the return type. Both now use a cached key union, and a literal key is looked up directly instead of being intersected with every key. With 5,000 keys in one namespace and one call per key, the check time went from 14.8s to 1.1s (TypeScript 6); with 1,000 keys from 0.75s to 0.27s. Keys, return types and errors are unchanged.
• perf(types): the selector API (enableSelector: true / 'strict') with context is no longer quadratic in the size of an object. To decide which keys a context keeps, the types scanned all keys of the object once for every key, also when TypeScript checks the selector with context widened to string. With 1,000 keys plus one context variant each, a namespace took 18.7s and failed with "Type instantiation is excessively deep and possibly infinite" (TS2589); 2,500 and more ran out of memory. The context variants of an object are now collected once, in one pass over its keys: 1,000 keys check in 0.69s, 5,000 in 3.1s. Long keys (whole sentences with keySeparator: false) work as before. Selected values and errors are unchanged.

v26.5.0

• feat(types): parseInterpolation: 'icu' and parseInterpolation: 'mf2' type t() options from the message's ICU MessageFormat arguments (i18next-icu) or MessageFormat 2 variables (i18next-mf2), so ICU and MF2 users no longer need parseInterpolation: false and lose argument checking. Missing, misspelled and wrongly typed arguments fail, and so does leaving out the options for a message with arguments (t('greeting')); that error names the missing arguments. Opt-in, default true is unchanged.
  • ICU: {name} takes string | number, {n, number}, plural and selectordinal take number, {d, date} and {t, time} take Date, select takes its case keys or any string (for other), and arguments nested in cases are required too. # and tags are not arguments, apostrophe quoting is read like intl-messageformat does.
  • MF2: {$name} takes string | number, a variable annotated with :number, :integer, :currency, :percent or :unit (inline or through .input / .local) takes number, :datetime, :date and :time take Date, :string takes string, option and markup variables (minimumFractionDigits=$digits, {#link href=$url}) are required too, .local variables are not arguments, and |quoted literals| and \{ escapes are skipped.
  • interpolationFormatTypeMap overrides a type by ICU format or MF2 function name, e.g. date: Date | number or a custom uppercase: string.
  • Applies to t(), getFixedT(), i18n.t, key prefixes, namespaces, the selector API and react-i18next's Trans values. Messages need literal types, as the resources file from i18next-cli's types command has them.
  • Type-check cost with 1,000 messages and one call each: 1.35s instead of 0.86s with false (TypeScript 6), 0.5s instead of 0.26s with TypeScript 7. Messages that no call uses cost nothing.
• fix(types): with the default (non-strict) key checks, an options object with a missing or misspelled interpolation variable now reports the missing variable (Property 'name' is missing) instead of '{ nmae: string }' is not assignable to type 'string' from the default-value overload.

v26.4.7

• perf: cloneInstance() no longer inherits preload. loadResources() adds every preload language to each load, and clones copied preload from the parent, so a clone's init() and every changeLanguage() walked all preloaded languages × all namespaces through queueLoad() / hasResourceBundle(), although the parent had already loaded them into the shared store. With i18next-http-middleware (one clone + changeLanguage() per request), 25 preloaded languages and 20 namespaces, that was most of the per-request CPU: the reproduction from the issue went from ~90 µs to ~10 µs per request, the same as with a single language. A clone now only loads what it uses itself: its changeLanguage() no longer waits for parent preload languages that are still loading (the parent's own init() still does), and clone.loadNamespaces() loads the new namespace for the clone's language and fallbacks instead of every preloaded language. clone.loadLanguages() works as before, the parent instance is unchanged, and passing preload to cloneInstance() keeps the old behavior. Thanks @​theMostCuriousHomunculus for the detailed report (#2451).

v26.4.6

• fix: a fallback language whose formatted code is already in the hierarchy is no longer added a second time. toResolveHierarchy() checked the raw fallbackLng value against the list, but the list holds formatted codes, so any fallback written differently from its formatted form slipped through: lng: 'de-CH' with fallbackLng: 'de-ch' gave languages ['de-CH', 'de', 'de-CH'], and the same happened with fallbackLng: 'EN' + cleanCode, lowerCaseLng, and Intl aliases (iw-IL → he-IL). Missing keys were looked up in the same language twice. Only exact duplicates are removed; the order is unchanged. Thanks @​lprnmns (#2450).

The joined value was extended with lastKey in the place of the resolved lookup, so with postProcessPassResolved a post processor got no usedLng, usedNS or exactUsedKey (t('steps', { joinArrays: ' / ' }) reported undefined/undefined:undefined). This affected the subliminal post processor used by the locize InContext editor, which could not map a joined array to its key. The nesting recursion guard did not get the parent key either, so arrays that nest each other (listA: ['a', '$t(listB)'], listB: ['b', '$t(listA)']) threw Maximum call stack size exceeded. They now stop at the guard, as strings do. An i18nFormat plugin with handleAsObject and parse also no longer throws Cannot read properties of undefined (reading 'usedNS') on joined arrays. Thanks @​nk-batman21 (#2458).

26.5.7

• fix: with the default cacheInBuiltFormats: true, built-in formats now also work when the t() options contain a BigInt or a circular object. The cache key was built with JSON.stringify over all options, including the interpolation values, which throws on those, so every built-in format in that call returned the raw value: t('num', { val: 12345678901234567890n }) with 'Total: {{val, number}}' returned 'Total: 12345678901234567890' instead of 'Total: 12,345,678,901,234,567,890', and passing an object with a back-reference (like an ORM entity) left all numbers, dates and lists of that call unformatted. When the key cannot be built, the value is now formatted without the cache, as with cacheInBuiltFormats: false. This also applies to formatters added with addCached. Other calls still use the cache as before. Thanks @​nk-batman21 (#2457).

26.5.6

• fix: cloneInstance({ forkResourceStore: true }) now copies the resources at every level. It copied them only down to the namespace objects, so nested keys and arrays stayed shared with the original instance: addResource() with a nested key (fork.addResource('en', 'translation', 'greeting.hello', 'Hi')) or a deep addResourceBundle() on the fork also changed the original instance and every other fork. Flat keys were already isolated. Forking a large store takes a bit longer: with 300k keys in nested groups, about 11 ms instead of 3 ms per fork. Clones without forkResourceStore still share the store as before. Thanks @​nk-batman21 (#2456, follow-up to #2270).

26.5.5

• fix: with the default skipOnVariables: true, a {{placeholder}} inside a value inserted with an unescaped {{- var}} now stays literal, as it already did for {{var}}. The escape pass ran after the unescaped values were written and scanned them again, so t('{{- a}}', { a: '{{b}}', b: 'c' }) returned 'c' instead of '{{b}}'. With pre-built HTML that carries user text, like t('You may contact {{name}} at {{- emailHTML}}.', { name, emailHTML }), that text could pull another variable of the same t() call into the output. Results with skipOnVariables: false, and values without placeholders, are unchanged. Compatibility note: a {{- var}} value whose placeholders were meant to be filled from the same t() call now keeps them literally; skipOnVariables: false restores the old behavior. Thanks @​nk-batman21 (#2455, reported in #1595).

26.5.4

• fix: with the default skipOnVariables: true, a {{placeholder}} inside an interpolated value now stays literal also when the same placeholder appears later in the translation. Each value was written with String.replace, which replaces the first copy of the placeholder text, and that could be the copy inside an earlier value: t('{{name}} has {{count}} items', { name: '{{count}}', count: 5 }) returned '5 has {{count}} items' instead of '{{count}} has 5 items'. The value is now written at the position of the matched placeholder. Results with skipOnVariables: false are unchanged. Thanks @​nk-batman21 (#2454, reported in #1595).
• fix: with useRawValueToEscape: true, a non-string value in an unescaped {{- var}} placeholder or with escapeValue: false no longer throws val.replace is not a function; it is converted to a string like any other value.

26.5.3

• fix(types): with the selector API, a plural key now requires count also when the call passes an explicit ns. t(($) => $.item) already failed without count, but t(($) => $.item, { ns: 'items' }) compiled, although at runtime it looks up item instead of item_one / item_other and returns the key. It now fails the same way, also with ordinal: true, defaultValue, an ns array, a key prefix and i18n.t. Calls with count, context, returnObjects: true and arrays of selectors, as well as return types, are unchanged. Thanks @​nyarthan (#2452).

26.5.2

• fix(types): on TypeScript 7, a t() call with a missing, misspelled or wrongly typed option now reports that option again (Property 'album' is missing, Type 'string' is not assignable to type 'number'), as TypeScript 5 and 6 do. TypeScript 7 elaborated the error against the default-value signature instead and ended in '{ count: 3; albm: "Summer"; }' is not assignable to type 'string': on a failed call TypeScript explains the last of the equally matching signatures, and TypeScript 7 sorts the 3-element [key, defaultValue, options?] last. It is now written as two signatures, [key, defaultValue] and [key, defaultValue, options]. This affects the default key checks with i18next {{name}} messages as well as parseInterpolation: 'icu' and 'mf2'. Which calls compile, their return types and the error positions are unchanged on TypeScript 5.9, 6 and 7.

26.5.1

• perf(types): type-checking t() calls against a large namespace is no longer quadratic in the number of keys. TypeScript does not cache keyof of an object type, and the types rebuilt the union of all keys of a namespace once per key while building the key union, and again in every t() call to look up the return type. Both now use a cached key union, and a literal key is looked up directly instead of being intersected with every key. With 5,000 keys in one namespace and one call per key, the check time went from 14.8s to 1.1s (TypeScript 6); with 1,000 keys from 0.75s to 0.27s. Keys, return types and errors are unchanged.
• perf(types): the selector API (enableSelector: true / 'strict') with context is no longer quadratic in the size of an object. To decide which keys a context keeps, the types scanned all keys of the object once for every key, also when TypeScript checks the selector with context widened to string. With 1,000 keys plus one context variant each, a namespace took 18.7s and failed with "Type instantiation is excessively deep and possibly infinite" (TS2589); 2,500 and more ran out of memory. The context variants of an object are now collected once, in one pass over its keys: 1,000 keys check in 0.69s, 5,000 in 3.1s. Long keys (whole sentences with keySeparator: false) work as before. Selected values and errors are unchanged.

26.5.0

• feat(types): parseInterpolation: 'icu' and parseInterpolation: 'mf2' type t() options from the message's ICU MessageFormat arguments (i18next-icu) or MessageFormat 2 variables (i18next-mf2), so ICU and MF2 users no longer need parseInterpolation: false and lose argument checking. Missing, misspelled and wrongly typed arguments fail, and so does leaving out the options for a message with arguments (t('greeting')); that error names the missing arguments. Opt-in, default true is unchanged.
  • ICU: {name} takes string | number, {n, number}, plural and selectordinal take number, {d, date} and {t, time} take Date, select takes its case keys or any string (for other), and arguments nested in cases are required too. # and tags are not arguments, apostrophe quoting is read like intl-messageformat does.

Looks like these dependencies are updatable in another way, so this is no longer needed.
