Bumps the i18next group with 2 updates in the / directory: i18next and react-i18next.

Updates i18next from 26.4.3 to 26.4.7

Release notes

Sourced from i18next's releases.

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).

v26.4.5

• fix: hasLoadedNamespace(ns, { lng }) no longer stays false forever when the passed in lng is loaded under another code, or not at all. It checked the load state of the raw lng, but loadLanguages() stores a language under its resolved code (de-ch → de-CH, de-CH → de with load: 'languageOnly') and skips a lng outside supportedLngs entirely (only the fallback gets loaded), so that state never got set. react-i18next's useTranslation(ns, { lng }) then never became ready: with useSuspense it kept throwing an already resolved promise and React retried forever (100% CPU, SSR never finished), without it the load effect re-rendered in a loop. It now checks the code the language is actually loaded under, and for a lng outside supportedLngs only waits for the fallback, which is also what t() resolves to. Calls without lng and the precheck (react-i18next's bindI18n: 'languageChanging') are unchanged (react-i18next#1934).

v26.4.4

• fix(security): the nesting regexp no longer backtracks exponentially (ReDoS) on an unclosed $t(. Its repeated group had overlapping alternatives ([^()"']+ inside (?:...)*?, and inside parentheses [^()] also matched quotes), so a string containing $t( without a closing ) made the engine try every way to split the text: about 2x the runtime per extra character, and a ~25 character value hung t() for minutes. With the default config this was reachable through any interpolated value (t('greet', { name: '$t(aaaaaaaaaaaaaaaaaaaaaaaa' })): escaping does not touch $, t or (, and the skipOnVariables check runs the regexp on the interpolated result, so nest: false did not help either. Every alternative now starts with a different character (plain char, ", ' or (), so there is only one way to match and the cost is linear. Quoted strings and one level of parentheses in nesting options keep working (#2336). The only difference: a lone " or ' inside unquoted parentheses within $t(...) is no longer matched. Affects 25.3.3 to 26.4.3. Thanks to Anisetti Chaitanya Eshwar Prasad for the responsible disclosure.
• fix(security): nest() now resolves $t(...) in a single pass and no longer nests text that came out of a resolved value. Every nested lookup reset the shared nesting regexp, so the loop started over from the beginning of the string after each match. That had two effects. First, a $t(...) inside a variable that the nested lookup deliberately kept literal (default skipOnVariables: true) was resolved anyway by the outer loop: with outer: 'A $t(inner) B' and inner: 'Hi {{name}}', t('outer', { name: '$t(secret)' }) rendered the secret translation. It now stays A Hi $t(secret) B, the same as without the outer nesting; with skipOnVariables: false it is still resolved. Second, the cost was quadratic when an unclosed $t( preceded many nestings, which matters when an app passes untrusted input as the key itself (t(userInput)): 20,000 nestings took ~1.4 s, now ~25 ms. The resolved value is now sliced into the result instead of going through String.replace, so $&, $`, $' and $$ stay literal as before (26.4.2).

Updates react-i18next from 17.0.16 to 17.0.19

Changelog

Sourced from react-i18next's changelog.

17.0.19

• fix: useTranslation with an inline selector keyPrefix (useTranslation('ns', { keyPrefix: ($) => $.role })) returned a new t on every render, so every effect, useCallback and useMemo depending on t ran again each time. The cached t was compared against the keyPrefix function itself, and an inline arrow is a new function on every render. It is now compared against the key the selector resolves to (with the same options and namespace list getFixedT resolves it with), so t keeps its identity as long as the resolved prefix does, just like a string keyPrefix. A selector that resolves to a different key still gets a new t, and i18next still resolves the selector on each t call as before. Fixes #1936.
• fix: useTranslation kept returning the previous t when only the namespace (useTranslation('a') → useTranslation('b')) or only the i18n instance (another instance with the same language, via props or I18nextProvider) changed on a mounted component. That t kept resolving against the old namespace or instance until something else (the language, the ready state, a bound i18n event) produced a new one. Both are now part of the check that decides whether the cached t can be reused.

17.0.18

• fix(Trans): with shouldUnescape, the default unescape now turns   and &[#160](https://github.com/i18next/react-i18next/issues/160); into a no-break space (U+00A0) instead of a regular space (U+0020). The regular space dropped what the entity is for: u nás or 10 km could wrap across lines, and consecutive  s collapsed into one space. This also matches IcuTrans, whose entity decoder already mapped   to U+00A0. Compatibility note: only affects shouldUnescape; snapshots or exact textContent comparisons of such text now contain U+00A0 (Testing Library's default normalizer still matches it as a space). A custom react.unescape function can restore the old mapping for text nodes. Thanks @​lprnmns (#1935).

17.0.17

• perf: useTranslation no longer unsubscribes and resubscribes its i18n listeners on every render. The subscribe callback handed to useSyncExternalStore depended on the merged options object, which is rebuilt whenever props is a new object: with no options (the {} default), with options passed inline (useTranslation('ns', { keyPrefix })), and through withTranslation and <Translation>. A new subscribe makes React resubscribe, so each render of each caller ran i18n.off and i18n.on in an extra effect. It now depends only on the instance and the bindI18n/bindI18nStore event names. No updates were ever missed, because React re-checks the snapshot after resubscribing; this only removes the churn, which adds up with many mounted components that re-render often. Reported via next-i18next#2349.
