🛠 Enhancements

WProofreader JS core (v3.46.6137)

  • Improved the feature settings experience. Controls now reflect actual feature availability for the selected language and configuration.
  • Features that are unsupported or disabled on the backend can now appear as unavailable instead of showing as enabled.
  • Added visible spelling suggestion descriptions. Classified AI-based spelling corrections now show a specific message in the UI in English, Spanish and German.
  • Improved issue count accuracy in badge. Corrections disabled through the disabledRules options no longer count as mistakes.
  • Added an “Apply all” button in Proofread in dialog mode that accepts every found suggestion at once, after you expand the dialog window fully.

API and configuration

  • Extended the get_info API with information about feature availability, including autocomplete, autocorrect, and style, allowing integrations to better reflect backend configuration.
  • Added an API getdicts action for retrieving user dictionaries, letting administrators list all dictionaries in an account. Each response returns up to 1,000 dictionaries. If more exist, a warning indicates that the list is truncated.

Localizations

  • Added interface language list localization for Kurdish (Turkey) and Thai.

Application server

AI-based proofreading

  • Enhanced Spanish AI-based proofreading to have better performance with underscores, unit changes and decimal separators.
  • Improved German AI-based proofreading to provide better performance on texts with parentheses and non-standard quotation marks written as >><< using greater-than and less-than signs.

Grammar

  • Added support for disabling individual proofreading rules or rule categories on the server side, so, for example, dash rules can be turned off correctly in every instance for cloud users.
  • Improved English grammar processing for capitalization patterns in technical identifiers (such as ID casing) and common word confusion pairs such as sou versus you.
  • Improved the handling of Swedish bil, art, and kol so if they are used at the end of the sentence and a following word is written in lowercase, we would suggest capitalizing that word. For example, Hon körde sin bil. vägen var nästan tom., the suggestion is Vägen.

Spelling

  • Expanded dictionaries with 840+ new words across English, German, Spanish, Portuguese, Italian, Dutch, French, and Greek, covering abbreviations, technology terms, common words, proper names, and linguistics terms.
  • Enriched cross-language dictionaries with 150+ proper names and abbreviations, covering companies and software applications such as Etsy, Depop, WebText, and USB-C.
  • Enhanced medical terminology for English, German, and Spanish with 120+ new terms, such as trichogram and hyporexia in English, anatómicamente in Spanish, and Implantatprüfung in German.
  • Added an English veterinary dictionary, disabled by default, covering 180+ terms and abbreviations such as GDV, oclacitinib, and Drontal. It covers all available English dialects and administrators can enable it as needed in self-hosted set-up. For cloud users, now it can be provided upon request to [email protected]. It incorporates terms from AGROVOC (FAO) combined with additional entries.
  • Extended measurement-unit abbreviation spelling suggestions, such as 2GB to 2 GB and 3GHz to 3 GHz, to uppercase and mixed-case abbreviations across many Latin-alphabet languages.
  • Added a rule for German (de_DE, de_AT) that lets administrators require the eszett (ß) instead of ss. By default, both forms are accepted; disabling ALLOW_SS_INSTEAD_OF_ESZETT makes ss spellings incorrect and suggests the ß form instead, and AI suggestions follow the same setting.
  • Improved handling of hyphenated words. Words that start with a hyphen, such as -anforderungen, are now recognized as correct when added to a dictionary with a leading hyphen, for most supported languages, except a few that don’t use hyphens this way, such as Arabic, Hebrew, and Japanese.

Style

  • Enhanced style rule precision in Spanish by adding contextual awareness to foreign-word suggestions. Suggestions for terms like power now exclude medical contexts such as Doppler, based on user feedback.

AI writing assistant

  • Reduced the minimum text length required to use the AI writing assistant from 100 to 30 characters, making AI-powered text actions available for shorter text.

Autocomplete

  • Improved autocomplete language handling by using the detected language as a fallback when automatic language detection has insufficient context, such as with very short text.
  • Improved authorization handling so autocomplete and autocorrect respect the languages enabled for a subscription.
  • Updated autocomplete authorization so it’s available only when at least one applicable check type is enabled for the language.
  • Improved autodetect authorization logic, so requests aren’t incorrectly rejected when an applicable check type is available for an authorized language.
  • Continued improving the filtering of autocomplete suggestions that contain sensitive, unexpected, or discriminatory language.

🐞 Bug fixes

  • Spelling engine (French): Suggestions incorrectly recommended removing the narrow nonbreaking space before punctuation, such as question marks and colons
  • Spelling engine: Hyphenated words following a number, such as 5-wöchigen or 16-years-old, were incorrectly flagged as misspelled
  • Spelling engine: Users couldn’t add abbreviations with doubled letters, such as PPP or CCCN, to custom dictionaries

🛡️ Security

  • Updated Netty to 4.2.17.Final, addressing multiple vulnerabilities in the application server’s networking component, including CVE-2026-75595.
  • Updated the MariaDB Java client from 3.4.1 to 3.4.3, addressing CVE-2026-55856, CVE-2026-55857, and CVE-2026-55858 in the application server’s database connectivity component.
  • Updated logback-classic from 1.5.38 to 1.6.3 to fix a directory traversal vulnerability in the application server’s logging component.
  • Updated Jackson Databind from 2.18.9 to 2.18.10, addressing multiple vulnerabilities in the application server, including unsafe reflection, untrusted deserialization, and uncontrolled resource allocation.
