@garo @jonathan859 @amir Correct, it will never be in the store. However, if you were using eci.dll version 6.1 with IBM TTS, it will sound identical. We don't currently have an update system because we're currently telling NVDA lies about the current addon version and what NVDA versions it's compatible with. This is both to force the addon to keep loading on newer NVDA versions without an update, and so that the "allow NVDA to gather usage statistics" setting does not allow NVAccess to gather accurate info on the addon.
