NVDA

What's new in this version:

- This release includes support for reading math content with MathCAT, which is now built-in to NVDA
- There have been several improvements to speech. Spelling and grammar errors can now be reported with a sound instead of speech when reading. You can now configure NVDA to automatically say all after successfully recognizing content, such as with Windows OCR. NVDA no longer reports the language being read as unsupported when the synthesizer supports the language but not the specific dialect. NVDA now supports 64-bit SAPI 5 voices.
- Braille support has also been improved. It now continues to work when switching to a secure screen, like the sign-in screen or User Account Control dialog. NVDA messages from the local computer are now shown in braille when controlling a computer via Remote Access. Spelling and grammar errors, as well as the number of items in a list in browse mode, can now be shown in braille. Other braille bug fixes, including in Microsoft Outlook and LibreOffice Writer, have also been added.
- In browse mode in web browsers, NVDA no longer treats controls with 0 width or height as invisible. This may make it possible to access previously inaccessible "screen reader only" content on some websites. Malformed links no longer prevent NVDA from reading content in Google Chrome and other Chromium-based browsers. The browse mode highlighter now appears on content recognition results, such as when using Windows OCR. In Microsoft Word, unassigned Quick Navigation commands to jump to references have been added. They are also now shown in the elements list.
- It is now possible to view virus scan results for an add-on from the Add-on Store. For add-ons that include one, you can also view an add-on's changelog. The reliability of background add-on updates has been improved.
- A new "Privacy and Security" category has been added to NVDA's settings dialog. The "Logging level" and "Allow NV Access to gather NVDA usage statistics" settings have been moved here from the "General" category. The settings for Screen Curtain have also been moved here from the "Vision" category. Additionally, Screen Curtain's settings are now configuration profile independent.
- The NVDA interface is now translated to Cambodian. Liblouis, Unicode CLDR and eSpeak NG have been updated. Added tables for English Grade 3, Japanese (Rokuten Kanji), and Macedonian uncontracted braille. Improved the Biblical Hebrew, Unified English Braille, Greek International, Hungarian, Norwegian, Portuguese 8-dot and Slovakian braille tables. Emoji localizations for Luxembourgish have been added.
- There have also been many other bug fixes and improvements.
- Important notes
- This release breaks compatibility with existing add-ons.
- Windows 8.1 is no longer supported. Windows 10 is the minimum Windows version supported. We recommend updating to Windows 11, or when that's not possible, to the latest Windows 10 version (22H2).
- 32-bit Windows is no longer supported. Windows 10 on ARM is also no longer supported.
- Wiris MathPlayer is no longer supported.

New Features:
In the Add-on Store:
- VirusTotal scan results are now available in the details for an add-on. An action has been added to view the full scan results on the VirusTotal website.
- A new action has been added to see the latest changes for the current version of an add-on.
- It is now possible to select which add-ons to copy for use during sign-in and on secure screens.
- Added built-in support for reading math content by integrating MathCAT.
- NVDA now supports 64-bit Microsoft Speech API version 5 voices.
- Added references (e.g. to footnotes and endnotes) to the elements list in Microsoft Word. Also added unassigned Quick Navigation commands to jump to the next/previous reference.
- In browse mode, the number of items in a list is now reported in braille.
- While reading text, spelling and grammar errors can now be reported with a sound instead of speech.
- Spelling and grammar errors can now be reported in braille.
- Added the possibility to report when multiple items can be selected in a control such as a list. This can be enabled using the "Report when objects support multiple selection" setting in NVDA's object presentation settings.
- In Visual Studio Code, the status bar is now reported when using the standard NVDA+end (desktop) / NVDA+shift+end (laptop) gesture.
- Automatically reading the entire result after a successful recognition is now possible via a new option in the Windows OCR settings.
- Performance improvements on ARM64 systems, such as with Qualcomm processors.
- A new unassigned global command has been added to toggle the "Play audio coordinates when mouse moves" option.

Changes:
- NVDA no longer supports Windows 8.1. Windows 10 (Version 1507) is the minimum Windows version supported. We recommend using Windows 11, or if that is not possible, the latest Windows 10 release (Version 22H2).
- NVDA no longer supports 32-bit Windows or Windows 10 on ARM
- Support for the MathPlayer software from Wiris has been removed

Component updates:
- Updated Liblouis braille translator to 3.36.0
- Added Japanese (Rokuten Kanji) Braille, Macedonian uncontracted braille and English Grade 3.
- Improvements to Slovakian, Norwegian, Hungarian, Portuguese 8-dot, Greek International, Biblical Hebrew and Unified English Braille.
- Updated BrlAPI for BRLTTY to version 0.8.7
- Updated Unicode CLDR to version 48. Also added emoji localizations for Luxembourgish
- Updated eSpeak NG to commit b0b605c8
- Added a button to the About dialog to copy the NVDA version number to the clipboard.
- When entering a secure desktop, an installed copy of NVDA will automatically disable Braille temporarily, so that the secure desktop copy can access the braille display.
- When controlling a computer via Remote Access with a braille display connected, messages spoken from the local computer are also shown in braille.
- The length of beeps used when "Line indentation reporting" is set to "Tones" or "Both Speech and Tones" has been reduced.
- In browse mode in web browsers, NVDA no longer sometimes treats controls with 0 visual width or height as invisible. This technique is sometimes used to make content accessible to screen readers without it being visible visually. Such controls will now be accessible in browse mode where they weren't before.
- The state of the Screen Curtain is no longer dependent on the configuration profile in use.
- A new "Privacy and Security" category has been added to NVDA's settings dialog. It currently includes Screen Curtain's settings (previously in the "Vision" category), and the "Logging level" and "Allow NV Access to gather NVDA usage statistics" settings (previously in the "General" category).
