Version 1.4.5 - October 25, 2025

• Ableton Live: Resolves bounce issues (slow render times, crashes) when using VST3 plugins. For now, this means that offline render will use the same settings as online render when using this plugin format in this host. We're in communication with Ableton regarding a more permanent solution.

• Logic Pro X - Separate offline oversampling settings are now fully supported in Logic Pro X

• Updated SDKs and frameworks to latest industry standard versions.

• Mac installers no longer require Rosetta 2 on Apple Silicon Macs. (For clarity, our plugins have supported Apple Silicon natively since 2021, but the installers were running in Rosetta 2 mode on those machines until now.)

• Windows installers updated to more stringent EV code signing certificate standard.

• New fonts for greater readability.

• Old macOS versions deprecated - all Kazrog plugins now require macOS 10.13.x or higher

• Newly expanded oversampling settings, up to 32x

• Apple Silicon Native AAX support (Pro Tools)

• Changes to oversampling settings are refreshed on the fly (rather than on session reload.)

• Separate offline oversampling settings is disabled in Pro Tools and Logic (these hosts will receive this feature when/if they respond to changes in reported plugin latency mid-session for PDC.)

• PluginDoctor support (avoid realtime oversampling settings above 2x for the most stable results.)

• Updated all frameworks and SDKs to latest stable versions.
