 - Moved packages out of `pkg/` (that was only used before `/internal` had a special meaning).
 - New `github.com/gomlx/compute/dtypes` repo will host `dtypes`.
-- Added `compute/xla` with the XLA backend implementation for github.com/gomlx/compute, moved out of 
-  github.com/gomlx/gomlx.
+- Package `compute/xla`:
+  - XLA backend implementation for github.com/gomlx/compute, moved out of github.com/gomlx/gomlx.
+  - Improved options handler, and added the `help` option/pluginName (prints out documentation),
+    and among others the `preallocate=false` and `memory_fraction=<float>` options to control pre-allocation
+    of memory (for CUDA) and the memory fraction to preallocate.
 - Package `shapes` for go-xla diverged enough (having quantization, dimension bounds, etc.) that it 
   stays a fork local to `go-xla`.
 - Updated to XLA/PJRT v0.104
 - Added `github.com/gomlx/compile/support/backendtest` compliance tests to `compute/xla` backend.
 - Fixed `ReduceWindow` window and base dilation attributes: it was previously using window dilation for base 
   dilation as well.
