Changelog: Release Notes and Updates

Welcome to the Babelize changelog. Here you'll find a record of what's new, what's improved, and what's fixed.

[v2.2.0] - 2026-10-16

React Native and Expo apps can be translated (beta), pull requests change only the lines that need to change, and lists your code also uses as data are translated where they're shown.

New

React Native and Expo (beta) — Expo Router, classic Expo and bare React Native apps are translated end to end: translations are bundled into the app, the device language picks the locale (expo-localization or react-native-localize), your entry point imports the i18n setup, and screen titles, Alert text and accessibility labels are translated. See React Native & Expo
Babelize SDK in React Native — @babelize/sdk runs in React Native with a detectLocale option, and the new @babelize/metro plugin writes the translations before Metro bundles. See React Native & Expo in the SDK docs
Monorepos — when the repository root isn't an app, the app package (for example apps/mobile) is translated, not the root
Organizations that restrict third-party apps — when your GitHub organization blocks the Babelize app or requires single sign-on, adding the repository explains why and links to installing the Babelize GitHub App or requesting approval. With the App installed, Babelize reads the repository once GitHub confirms your account can
Re-translate everything — schedule it in project settings, or turn it on in the Run dialog: the next run translates every string again instead of reusing earlier translations (and uses credits for all of them)
Redesigned project settings — sections for general settings, languages and the translation engine, language chips, an explicit Automatic engine option, a live preview of date, price and number formats, and Save enabled only when something changed

Improved

Static HTML/CSS/JS sites are generally supported — no longer in beta. Vue and React Native remain in beta
Pull requests change only what they need to — only lines with translated text change, plus the translation hook and import. Formatting, line endings and indentation stay as you wrote them, and a re-run changes nothing
Lists that are also data — a list shown as chips or options and also saved or sent to your API (NICHES, plan sizes) stays as you wrote it: a map from each value to its translation key is added next to it, and only what's displayed is translated
Plurals from your code — {count} item{count === 1 ? '' : 's'} becomes one plural message, translated form by form, instead of a word with an English "s"
Clearer messages for translators — placeholders are named after what they show ({dealEndsAt} rather than {0}), and the cloud translator keeps line breaks

Bug Fixes

Data is no longer translated — colors, roles, statuses, icon names, storage folders, object keys, TypeScript types, ISO dates and codes such as GST numbers were sometimes treated as text, which could break styling or send translated values to your API
Line breaks — \n in a template string is a real line break in the message, not a backslash and an n
Static sites: pages in subfolders — pages such as blog/post.html now load ../i18n.js, so they translate like the home page. Re-running repoints pages from earlier runs
Static sites: page titles and descriptions — <title> and the description, Open Graph and Twitter <meta> tags are translated too
Static sites: language list — the generated i18n.js lists your source and target languages, so the switcher and the fallback to the source language work

A large release: translate locally without an account, cancel runs, import and export translation memory, manage your subscription yourself, and Django out of beta. It also closes a full audit of billing, projects, runs, accounts and storage.

New

babelize translate — local translation — translate a project straight into your working tree from the CLI, with no Babelize account. Pair it with --report for a QA report file and --allow-partial when a few strings may fail
babelize check for CI — fails the build when locale files are missing keys or a translation broke a placeholder
MCP workflow tools — babelize_analyze, babelize_check, babelize_translate and babelize_review let Claude Code, Cursor and Codex localize a project locally. See MCP server
Cancel a run — stop a queued or running run from the dashboard or with babelize babels cancel <id>. You're only charged for strings it had already translated
Run history — filter by status and trigger, search across several projects, page through every run, and see who started each one. Run details show logs in order and only that run's warnings
Translation memory import and export — export as TMX or CSV, and import a CSV in merge mode (adds and updates entries) or replace mode (replaces this project's entries). Invalid rows are skipped and listed with their row number
Manage your subscription — the billing page shows when your plan renews, lets you cancel at the end of the period or resume, and opens Dodo's portal for your payment method and invoices
Replace a ZIP project's source — upload a new archive for an existing ZIP project
Django is generally supported — no longer in beta, verified end to end and listed next to React and Next.js. Vue and static HTML remain in beta. Limitations are on the Django page
JSX sentences as one message — text, values and inline elements such as links in one sentence become a single translatable string, so translations can reorder words naturally
Plural messages with the cloud translator — ICU plural and select messages are translated branch by branch
Translation problems per run — each run lists strings that failed or need review, and failed strings are retried on the next run
Live project chat — comments and replies update in real time

Improved

Translation quality — a curated UI dictionary (now including Polish) for common interface words, the source language is passed to the translator, and placeholders are protected so they come back intact
Glossary — terms are enforced without touching placeholders or URLs, CSV import can merge, and glossary commands are available in the CLI and MCP server
Unsupported frameworks are refused up front — a Laravel, Rails, Flutter or Angular project is turned away with the framework named, instead of failing on the first run
Python package managers — pip, Poetry, Pipenv, uv and PDM are shown on the project page

Bug Fixes

Downloads keep every translation — after a re-run that reused earlier translations, the downloaded locale files could contain only that run's new strings
Generated files are left alone — a re-run could rewrite Babelize's own i18n config and break the app
Navigation links stay separate — a row of links (Shop, Cart, Contact) was grouped into one string and could fail to translate
One failing string no longer fails a run — a re-run whose only new string failed was marked Failed, even though everything else was ready
Pull requests include every change — PRs now carry every file the run changed and are built on the commit the run started from. Update PR reflects the PR's real languages
Runs can't get stuck — one live run per project, a real time limit, and every failure ends the run cleanly. A failed re-run keeps your last good output
Deleted projects stay deleted — they disappear everywhere and are removed for good after 30 days. Archived projects are read-only, and restoring checks the owner's plan
Project files — each project's files now live in one folder; downloads are written safely, and cleanup never deletes translation history
Removing a language — failed with a server error
Team invites on paid plans — owners who had changed plan could be told their plan only allowed the owner
Email sign-in — showed your email instead of your name and avatar
Notifications — mark all as read keeps the list, the unread badge is accurate, and links go to the right place
Billing — repeated payment webhooks are handled once, refunds and disputes appear in your history, credit reservations settle exactly once, and plans granted to an account show their end date

Security

Billing data — billing tables and credit functions can only be changed by the server
Connected accounts — GitHub and Google tokens are encrypted at rest; your own AI provider keys are no longer cached outside the database
Accounts — deleting your account cancels billing and revokes sessions and API keys, with a 30-day window to restore it. Shared projects pass to a teammate instead of being left without an owner
Profiles and teams — closed gaps that let someone read another user's profile, take over an email address, or promote themselves to project owner

Changes worth knowing

Billing counts translations produced — runs are charged for strings actually translated, not for every string found. Cancelled or timed-out runs are charged for what they translated before stopping
Re-run once before your next pull request — project files moved to a new layout, so run each project once before raising a PR
Some older ZIP projects need a re-upload — if a run reports that the project's archive is missing, use Replace source
Locale and currency preferences are hidden until they apply across the app
Packages — @babelize/cli 1.1.3, @babelize/engine 0.1.2 and @babelize/types 0.1.2. The CLI now respects a saved API URL, prints clean JSON with --json, fails clearly in non-interactive mode, and uses consistent exit codes
License — the repository and published packages are Apache-2.0

[v2.0.7] - 2026-09-29

A bug fix release. The headline is sign-in: signing in with GitHub, Google or GitLab had stopped working.

Bug Fixes

OAuth sign-in repaired — signing in with GitHub, Google or GitLab landed back on the sign-in page with ?expired=true. The session is issued as a cookie, and the dashboard's proxy for the OAuth callback was dropping that cookie before it reached the browser, so the sign-in completed and then immediately had nothing to show for it. Email and password sign-in was never affected
Onboarding no longer redirects — finishing or skipping the welcome dialog left you on the import wizard rather than the dashboard you were already looking at

Changes worth knowing

Refreshed onboarding — the welcome dialog is a two-column layout now, and it stays out of your way: finishing it returns you to the dashboard
Theme-aware favicon — the tab icon follows your browser's light or dark theme
Shared brand assets — the logos live in one place in the repo instead of a copy per app

[v2.0.6] - 2026-09-23

A bug fix release. No new features — this one is security hardening and correctness, following a full audit of the platform.

Bug Fixes

Admin pages restored — several admin screens (user roles, subscription languages, role management) returned "Forbidden" to genuine admins. The permission check behind them queried a column that does not exist, so it answered "not an admin" for everyone. Those endpoints work now
Account data showing as missing — accounts created with email and later linked to Google or GitHub ended up with two identities, and projects, subscriptions and billing history could appear missing. Affected accounts are reconciled and the cause is fixed, so it cannot recur
Notifications update live — the notification bell captured your runs once at page load and never refreshed, so runs finishing later never appeared. It now reflects current activity
Real-time updates after reconnect — when the live connection dropped, project and run updates would silently stop resubscribing. They now resume correctly
No more dashboard flash — protected pages are checked before rendering, so signed-out visitors are redirected instead of briefly seeing the app shell
Uploads — a crafted ZIP could write files outside its workspace during extraction. Archive handling is now bounded to the project workspace
Payment webhooks — a duplicate webhook route could never verify its signature. Both provider URLs now reach the verified handler
Translation memory and billing history are paginated instead of loading every row at once

Security

Live updates — the real-time connection accepted a token without verifying its signature, meaning a forged token could subscribe to another account's runs. Signature verification is now mandatory
Project insights — insights for any project could be read by any signed-in user who knew its ID. Now restricted to project members
Request protection — CSRF tokens are signed by the server, so a token we did not issue is rejected. The protection can no longer be disabled in production by configuration
Access tokens — no longer stored in browser storage, where any script on the page could read them
Database access rules — row level security added to the last three unprotected tables, including the one that records who is an admin. Internal fallbacks that could bypass these rules have been removed
Rate limiting — could be bypassed by rotating a request header; limits now derive from the real client address and fail closed when quota state is unknown

Changes worth knowing

Runtime SDK translation now consumes AI credits. POST /v1/translate was previously unmetered. If you use @babelize/sdk for runtime translation, it now draws on your credit balance like any other translation
One run per project at a time. Starting a run while another is in progress returns 409 RUN_IN_PROGRESS instead of both runs corrupting each other's workspace
Paginated responses. Translation memory and billing history now accept ?page= and ?limit= (default page=1; default limit is 100 for translation memory and 50 for billing history). Clients that expected every row in one response should page
Next.js 16 — @babelize/sdk and @babelize/next now declare support for Next 16

[v2.0.5] - 2026-08-26

Features

Single-package SDK — React and Next.js bindings are now subpath exports of @babelize/sdk (@babelize/sdk/react, @babelize/sdk/next). One install for React, Next, or vanilla apps. @babelize/sdk-react and @babelize/sdk-next are deprecated in favor of the subpaths
ICU MessageFormat — babelize.icu() translates ICU messages (plural, select, selectordinal, nested) while preserving structure, placeholders, # pound, and number/date/time formatters. Exposed on useBabelize() in React. See the ICU guide
Full CLDR plural forms — babelize.p() now requests all six CLDR forms (zero/one/two/few/many/other), so Polish, Arabic, and Russian get correct few/many/zero/two translations instead of falling back to the generic plural. The Next.js build plugin now extracts plurals too
CLI CI safety — the CLI is now pipeline-safe: cancelled prompts exit 128 (never 0), a global --yes/--non-interactive flag plus CI auto-detection prevents prompts from hanging, --password is a registered auth login/signup option, and run status --watch --json emits final JSON. See CI/CD
Shared scanner — new @babelize/scanner package shared by the Vite and Next build plugins (no more extraction drift between them)

Bug Fixes

Extraction reliability — identical JSX labels at different lines are all extracted (dedup by location, not text); Vue templates handle multiline text and normalize {{ var }} → {var}; HTML data-i18n is honored on any ancestor; CLI and MCP scan tools are drift-guarded to stay identical
NLLB output artifacts — FLORES language tokens (eng_Latn) and the unknown-token marker ⁇ (U+2047) are stripped at both the Rust translator and the backend safety net, so translated output is clean
API key docs — corrected api-keys CLI docs to match the real commands (api-keys babelize create <name>)

[v2.0.4] - 2026-07-28

Features

Persistent Downloads — Translation ZIP files now stay accessible in your dashboard until you delete them (auto-cleaned after 30 days)

Bug Fixes
