更新日志

What’s new in NVDA 2022.3
October 4, 2022
New Features:
In the Windows Console Host used by Command Prompt, PowerShell, and the Windows Subsystem for Linux on Windows 11 version 22H2 (Sun Valley 2) and later:
Vastly improved performance and stability. (#10964)
When pressing control+f to find text, the review cursor position is updated to follow the found term. (#11172)
Reporting of typed text that does not appear on-screen (such as passwords) is disabled by default. It can be re-enabled in NVDA’s advanced settings panel. (#11554)
Text that has scrolled offscreen can be reviewed without scrolling the console window. (#12669)
More detailed text formatting information is available. (microsoft/terminal PR 10336)
A new Speech option has been added to read character descriptions after a delay. (#13509)
A new Braille option has been added to determine if scrolling the display forward/back should interrupt speech. (#2124)
Changes:
eSpeak NG has been updated to 1.52-dev commit 9de65fcb. (#13295)
Added languages:
Belarusian
Luxembourgish
Totontepec Mixe
When using UI Automation to access Microsoft Excel spreadsheet controls, NVDA is now able to report when a cell is merged. (#12843)
Instead of reporting “has details” the purpose of details is included where possible, for example “has comment”. (#13649)
The installation size of NVDA is now shown in Windows Programs and Feature section. (#13909)
Bug Fixes:
Adobe Acrobat / Reader 64 bit will no longer crash when reading a PDF document. (#12920)
Note that the most up to date version of Adobe Acrobat / Reader is also required to avoid the crash.
Font size measurements are now translatable in NVDA. (#13573)
Ignore Java Access Bridge events where no window handle can be found for Java applications. This will improve performance for some Java applications including IntelliJ IDEA. (#13039)
Announcement of selected cells for LibreOffice Calc is more efficient and no longer results in a Calc freeze when many cells are selected. (#13232)
When running under a different user, Microsoft Edge is no longer inaccessible. (#13032)
When rate boost is off, eSpeak’s rate does not drop anymore between rates 99% and 100%. (#13876)
Fix bug which allowed 2 Input Gestures dialogs to open. (#13854)
Changes for Developers:
Updated Comtypes to version 1.1.11. (#12953)
In builds of Windows Console (conhost.exe) with an NVDA API level of 2 (FORMATTED) or greater, such as those included with Windows 11 version 22H2 (Sun Valley 2), UI Automation is now used by default. (#10964)
This can be overridden by changing the “Windows Console support” setting in NVDA’s advanced settings panel.
To find your Windows Console’s NVDA API level, set “Windows Console support” to “UIA when available”, then check the NVDA+F1 log opened from a running Windows Console instance.
The Chromium virtual buffer is now loaded even when the document object has the MSAA STATE_SYSTEM_BUSY exposed via IA2. (#13306)
A config spec type featureFlag has been created for use with experimental features in NVDA. See devDocs/featureFlag.md for more information. (#13859)
