Tue. November 25, 2025 | |
| 21.0.546 | The @foo.tuplesize and @foo.tuple bindings will work with auto-tuple size of 0 specified in the manual bindings; previously it was only working for the "#bind point foo float?" automatic binding. |
Tue. November 25, 2025 | |

Tue. November 25, 2025 | |

| 21.0.541 | Fixed a bug where deep camera map in EXR format had incorrect channel names for beauty plane ('C.r', 'C.g', 'C.b' instead of 'R', 'G', 'B'). |
Thu. November 20, 2025 | |
