What's new for Windows 10 October 2018 Update (Version 1809)
The following features, tools, developer guidance, samples, and videos have been made available for the Windows 10 October 2018 Update.
|1809||Win32||UI Automation supports Active Text Position Change events||UI Automation providers can explicitly set a starting position within a text range. Assistive technology (AT) clients can then convey this position to a user. For example, if a user clicks a link to an anchor on the same page (a bookmark link), the new location is provided to the AT.||IUIAutomation6 interface|
|1809||Win32||UI Automation supports event coalescing||Improves performance by attempting to detect, filter, and ignore duplicate sequential MSAA and UIA TextChanged events raised by some providers.||IUIAutomation6 interface|
|1809||Win32||UI Automation supports connection recovery behavior||Messages from a UI Automation client to a provider are suspended (for two seconds, by default) if the provider is non-responsive. This reduces the frequency of extended timeouts, and minimizes flooding a non-responsive provider with events and requests.||IUIAutomation6 interface|
|1809||UWP||Enhanced screen reader services||AT clients know the audible screen reading location (control or content) and the reading mode.||ScreenReaderService Class|
|1809||Win32, UWP||UI Automation supports dialog windows||UI Automation providers can mark UIA elements specifically as dialog windows. ATs often present dialogs differently to users.||IUIAutomationElement9
|1809||UWP||Text scaling||Scales text size in applications and web pages.||UISettings.TextScaleFactorChanged Event
