- See public description below.
- Stopped incrementing the iteration count in saveStats().
- `sizeof(mjSolverStat) == 40`, so this ends up costing 160KB, up from 40KB.
BEGIN_PUBLIC
Changed the size of `mjData.solver`, the structure used to collect solver diagnostic information. The array is now of length `mjNISLAND * mjNSOLVER`, where each row of length `mjNSOLVER` contains separate solver statistics for each constraint island. Until solver islanding is implemented, only row 0 is used.
- The new constant `mjNISLAND` is set to 20.
- `mjNSOLVER` is reduced from 1000 to 200.
- Added `mjData.solver_nisland`, the number of islands for which the solver ran.
- `mjData.solver_niter` (renamed from mjData.solver_iter) and `mjData.solver_nnz` are now integer vectors of length `mjNISLAND`.

Add missing `ctrl` attribute to keyframe indexer.
END_PUBLIC
Context: Making an LQR notebook for the Skydio drone and wanted to read the ctrl attribute in the keyframe stored in the XML.

Python 3.7 reaches end-of-life on 27 June 2023 (https://devguide.python.org/versions/), and future versions of MuJoCo (after 2.3.6) will no longer support it.

Going forward, the version number at head will be kept one ahead of the latest released version. The rationale behind this change is so that it is clear that the source code at head is more recent.

This change also requires user scripts to explicitly synchronize changes to physics state to the viewer. The Simulate class was reconfigured so that certain UI events are handled during this sync operation, outside of the render loop on the main thread. These correspond to operations that require access to the full mjModel/mjData.
To support other, more interactive operations (e.g. camera movements), a new mjvSceneState struct is introduced which captures only the portion of the physics state required for scene re-rendering. The mjvSceneState is updated from mjModel/mjData during the viewer sync operation, and is significantly cheaper than a full mj_copyModel and mj_copyData.

Before this change, these functions can return before an internal call to `mj_forward`, which results in a race condition if the user script then tries to modify the physics state.

This allows rendering from non-main threads as the context is not tied to a Cocoa window.
