0.28.2

Added

• io.savevalue for writing a value to a file in the binary data format.

• Better detection of host OOM, although still unreliable on systems with
  overcommit.

• With GPU backends, unstructured copies are now sometimes a lot faster, as the
  run-time now dynamically tries to choose the best copying order.

Fixed

• futhark lsp now handles textDocument/semanticTokens/full in a trivial way
  to work around a bug in the lsp library.

• futhark lsp had an off-by-one error when computing column offsets.

• Incorrect constant folding of x %% x.

• Signed division by -1 is now properly defined.

• A compiler crash when unifying parametric module types. (#2581)

• Invalid simplification of indexes could lead to compiler crash.

• Multicore backend contexts would become unusuable after the first failure.

• Partial arithmetic operations accessed through prelude modules (like i32./)
  lacked safety checks.

• u16.f16, u16.f32, and u16.f64 was defective in the interpreter.

• Various cases where generated C code might exhibit undefined behaviour.

• Various compiler crashes (#2588, #2587, #2586).

• An invalid simplification that could lead to incorrect results (#2585).

• Various fixes to binary input validation.

• Handling of unsigned integer exponents in the interpreter.

• Bitshift operators are now fully defined, with masking of problematic shift
  amounts.

• f16.sgn was missing on some targets.

• Various obscure floating-point errors in the ispc backend.
