Version 25.3.0 release notes

Thank you for using Wotja 25! IMPROVEMENTS - Plug-ins: Audio Output Setting > Audio Device shows the sample rate and estimated latency - Plug-ins: For better synchronization with other tracks in a DAW the estimated latency of the Plug-in is now reported to a DAW that supports that (e.g. Ableton Live 12) - Plug-ins: Added Audio Output Setting > Audio Block Count (previously only available in non-Plug-in variants) - Plug-ins: Audio Output Setting > Audio Block Count can now be set down to 2 (previous limit was 3; new default is 20) - only use such a low value if you're pushing for minimum audio latency and be aware that doing so might lead to some Wotja audio break-up issues, especially with CPU intensive content - Display modes now show any mix-included background image using an aspect fill instead of a stretch fill - Other minor improvements FIXED - Desktop Plug-ins: Cmd-W no longer closes the Documents Window - Incorrect display of an image in a mix when the mix was played in URI Player and the device orientation changed - Other minor fixes FULL DETAILS: wotja.com/releases/#w25-3-0 P.S.
