What's new in 15.1.0002

DBT 15.1 is our first version with native Apple Silicon and eBraille support, and has several other new and improved features.
Built for Modern Macintosh Computers
- DBT will no longer require Rosetta to run on modern Macintosh®computers.
- Builds for Macintosh computers with Intel processors may no longer be available. If you require one, please inquire.
- DBT/Mac for Apple silicon cannot import MathType objects embedded in .docx files.
eBraille Support
- DBT 15.1 supports export of eBraille files from braille documents.
- Command line support for eBraille conversion is included, using a new /ebrl command line switch.
Other Exporter Improvements
- Formatted braille files may be saved in Unicode Braille Patterns encoding.
Accessibility (Windows Only)
- JAWS voicing of the translated line while editing large braille files is better-synchronized to what is shown on a connected braille display..
- JAWS reading of unusual character values from the status line has been corrected.
Importers
- An arbitrary size limitation within DBT has been lifted, allowing for importing larger .docx files.
- The .docx importer now adds a hard space after the function name for a math function.
- The .docx importer will now recognize both old and new definitions of Red, as well as similar custom colors.
- Problems placing images using TactileView 3 have been corrected.
- Importation of mathematical named functions from LaTeX and MathType (Windows only) has been improved.
Editing and User Interface
- When hiding codes on the translated line, DBT will hide even codes at the end of the line.
- The status line display font can be set in the Global Fonts dialog.
- Several codes have been added to the Codes List dialog.
Language Support
- The English/Unified (UEB) print-to-braille translation table (file enuncp.btb, now version 16;4 260707) has been updated to suppress the contraction "con" in the word "cons" in most instances, excepting only certain cases where the immediate context makes clear that "cons" is a formal or informal abbreviation of a longer word where "con" would be contracted, e.g. "ex-cons" (short for "ex-convicts"). This is an effort to more commonly comply with RUEB 2024 section 10.6.4.
- DBT now includes an updated version of the BANA Template for Microsoft® Wordâ ¢: BANA Braille 2026. Both English (UEB) - BANA DBT templates and the style map file for them are updated as well. Service release 2 contains a further importer update. …
