v1.29 was actually released on 8th August, however it has been summer vacation and so the Hyperion website update was delayed.
v1.29 features a bug fix for FL Studio users, UI presentation improvements (more defined areas/highlighting/some new icons/faster tooltips/first time usage tips pop-up), a new utility node (Stereo Swapper - swaps left and right channels (can be useful in feedback loops for example)), option for hard pan on the Stereo splitter outputs, optional 'true' panning mode for the amp/mixer/audio out nodes which pans audio from the opposite channel into the panned to channel (otherwise the default is a level balance control).
The next release is currently in development - there are under the hood updates to the the entire audio framework including rendering updates, and also there will be updates that should resolve potential threading issues on Apple silicon. Hyperion node engine has been getting some additional memory safety tweaks and optimizations to reduce memory footprint.
There will be a few additional tweaks and features + a few more patches however going forwards the plan is to develop patch packs to be made available separately.
