金. 7月 10, 2026
21.0.773

Fixed a bug where HDAs larger than approximately 1GB could be saved without error messages, but reloading them would produce a corrupted asset reloaded as empty, unlocked nodes. Now, HDAs will cleanly support up to 4GB in total size, with internal sections no larger than 2GB. Saving an HDA that exceeds the supported size now fails with an error instead of writing an unreadable file. Previously written assets that exceeded the 1GB limit can now also be recovered.

金. 7月 10, 2026

Fixed a bug with the "Relative to Root" scheduler file transfer mode failing when copying a file that isn't in the root directory. File from different directory trees will fall back to using the "Flat Copy" transfer method instead.
