weblate

Released on May 15th 2026.

New features

• Added MDX files support for translating Markdown text while preserving JSX syntax, with File format parameters shared with Markdown files for line wrapping, code blocks, front matter, and placeholder handling.

• Added extended LLM translation context for automatic suggestions, covering string context, explanations, secondary-language translations, plurals, failing checks, and placeholders.

• Added a digest-only translation activity summary notification, see Notifications.

• CSV and XLSX downloads in Downloading translations now export plural strings as separate plural-form rows that can be imported back.

• Added Gettext PO and POT File format parameters to control whether Weblate updates the Language-Team, Last-Translator, X-Generator, and Report-Msgid-Bugs-To headers.

• Added a backup to run configured backup services synchronously.

• The translation memory lookup API can now skip fuzzy matching with the exact query parameter.

• Added Translation files CDN to publish translation files to the configured CDN.

Improvements

• Using DOS line endings can now be configured using the dos_eol File format parameters.

• OpenAI and Alibaba no longer require their vendor Python SDKs.

• Audited project and component setting changes are now recorded in history.

• Gerrit review pushes now use Push branch as the target branch.

• Weblate now checks whether CACHE_DIR allows executing generated helper files.

• The Software Bill of Material is now generated during release and published as a versioned release asset instead of being stored in the source repository.

• The translating page now separates screenshots from string information, collapses rarely used string details, and groups glossary and screenshot actions more consistently.

• Project access management now paginates users and better explains site-wide automatic team assignments.

• Added provider-oriented code hosting documentation and Gettext-style Plural formula guidance.

• The Python wheel no longer ships source translation catalogs, test files, or deployment example files, reducing the installed package size.

• The engage page now highlights actionable translation task buckets for newcomers.

• RSS feeds can now use the same filters as the changes browsing page.

• Update gettext template (Django) now supports gettext PO files used as templates when they are excluded by the language filter.

• Reworked Weblate threat model into a contract-style document.

Bug fixes

• Hardened search previews and Automatic suggestions suggestion origins against XSS, and stopped exposing database error details in upload failures.

• Screenshot URL uploads, remote HTML extraction in JavaScript localization CDN, and URL health-check redirects now reject internal or non-public targets by default.

• Gerrit review pushes now reject target branches containing push options, track the target branch before invoking git-review, and suggest short branch names when full refs are supplied.

• Category Announcements no longer appear across the whole project, and translation announcement deletion now honors language-scoped permissions.

• Merge request pushes now refresh stale fork remotes after changing repository hosting.

• Plural counts parsed from translation file headers are now bounded, and plural formulas are rejected when they can evaluate outside the configured plural form range.

• Per-project access tokens expiring today now remain valid until the end of the day.

• Malformed ALTCHA CAPTCHA submissions and repository URLs in webhook payloads no longer cause server errors.

• Placeholders now merges overlapping non-nested spans from multiple flags.

• Backing up and moving Weblate logs no longer include OpenSSH post-quantum key exchange warnings from remote Borg connections.

• Category repository paths are now handled more safely during cleanup and moves.

• Locked component pages now show an unsubscribe action after subscribing to unlock notifications.

• Project level backups imports now restore in the background to avoid web worker memory limits.

Compatibility

• The dos-eol flag is no longer supported. Use the dos_eol File format parameters instead.

• The registration CAPTCHA now uses the ALTCHA widget v3 protocol with Argon2id proof-of-work.

• The set_language_team project attribute has been replaced with the po_set_language_team file format parameter at the component level; see File format parameters.

• Weblate now uses calendar versioning for releases, see Release cycle.

• Weblate now uses stricter dependency version constraints to better control runtime environment.

Upgrading

Please follow Generic upgrade instructions in order to perform update.

• The ALTCHA_MAX_NUMBER setting has been replaced by ALTCHA_COST, ALTCHA_MEMORY_COST, and ALTCHA_PARALLELISM; please adjust your settings accordingly.

• The upgrading policy was changed, and upgrades are only supported from the current or previous calendar year.

• The COMMENT_CLEANUP_DAYS and SUGGESTION_CLEANUP_DAYS settings are migrated once to site-wide Stale comment removal and Stale suggestion removal add-ons; configure those add-ons instead.
