v0.2.1

TreeAMR v0.2.1

Diff since v0.2.0

TreeGRRMHD's mesh requests (#20). Additions only; existing code is unaffected.

• A state vector over several field sets: statelength, statevector, statearray, scatter! and gather! take a tuple of field sets; staterange and stateview are new exports; volume_weighted_norm(sets, u).
• map_blocks!(…; workgroupsize) passes a workgroup size to a device launch (ignored on the CPU).
• Per-set boundary hooks in regrid!, fs => (schedule, hook).
• adapt_to_initial_data! over several field sets at once.
• Outflow faces, Forest(…; outflow = ((lo, hi), …)): zero-gradient ghosts filled by the schedule on every backend and across ranks, without a hook.
• Bounded conservative prolongation, Operators(…; family = Conservative, prolongation = 3, bounded = true): the ghost fill and the regrid create no new extrema, and the transfer stays conservative and exact for linear data. Also accepted at prolongation = 1, which is bounded already.

The forest's face kinds moved into one field, which changes the companion interface: TreeIOHDF5 needs a release that accepts this version.

v0.1.8

TreeAMR v0.1.8

Diff since v0.1.7

Faster copy kernels, chiefly on a device (#18). On a device, scatter!, gather! and the ghost fill launch over one axis with precomputed 32-bit inverses instead of 64-bit divisions, and pure copies skip their weights. H200, 20 variables, G = 3, 512 × 32³: scatter! 0.335 → 0.140 ns/point, gather! 0.441 → 0.136, fill_ghosts! 0.399 → 0.296. On the CPU, one-thread scatter!/gather! are about 3× faster. Results are bit-identical to 0.1.7; no API change.
