Release overview

Language Weaver Edge 8.7.1.0 is a major update release which adds support for the new Pro translation models. The Pro models use a Large Language Model (LLM) Engine to perform the translations.

What's New?

• Pro Models

  • Language Weaver Pro models are the latest generation of translation models from Language Weaver. These are LLM-based translation models that offer greatly enhanced fluency and translation quality on outputs.

  • Pro models of various sizes are supported via LLM Engines, which were introduced in 8.7.0.0:

    • Hardware requirements will vary based on the specific model, however at minimum, Pro models require:

      • 2 CPU cores, 1 GPU, and 24GB GPU RAM to run (we recommend at least an NVIDIA A10 GPU)

      • At least 1 Processing Unit (PU) per engine

  • Supported on Windows and Linux: the G models are supported on both Windows and Linux, while the T models are Linux only but provide better throughput.

  • Pro models running at least 1 PU will process translations at up to 2,000 words per minute (WPM). additional PUs can be assigned to increase throughput speeds.

• CSV and TSV input types supported

  • Separators supported for CSV inputs include: comma, semicolon, tab, pipe.

• RWS Theme update

  • Default UI theme has been updated to reflect the latest RWS branding.

Enhancements

• Improved performance for audio transcriptions.

• Improved PDF handling with better format preservation.

• Reduced Job Engine memory usage for translations that use large dictionaries with fluent terms.

• Added automatic language detection translation fallback for dialect languages: for example if the input is detected as French but there is only a "French Canadian" LP available, use it for the translation.

• Added a section for Labels in the Reports view.

• Allow labels to be applied for synchronous translations.

• Allow feedback import of entries that don’t have an explicit ‘srcLanguage’ attribute set for the ‘<tu>’ element.

• Allow case insensitive matching for the Profile Language Model option.

• Added an installer option to modify the optional components for an existing LWE installation.

Fixes

• Fixed incorrect language pair selection when using Multilingual Document Translation with a combination of Edge Cloud engines and local engines.

• Fixed greedy pre-fetching of jobs by a Job Engine when it starts up, which would result in starving other Job Engines.

• Fixed slow translation for large PDF outputs that contain watermark background text.

• Fixed delayed release of computation resources after a large PDF output job is cancelled.

• Fixed incorrect reporting of the job WPM rate as 0 for large PDF>PDF jobs.

• Fixed security vulnerability for the OpenSSL library: CVE-2025-15467
