Changes in version 0.3.0                        

Features

  - Added support for CHLO ops, a higher-level companion dialect to
    stableHLO that is lowered to stableHLO during compilation. New ops:
      - Inverse trig: hlo_acos(), hlo_asin(), hlo_atan().
      - Hyperbolic: hlo_cosh(), hlo_sinh(), hlo_acosh(), hlo_asinh(),
        hlo_atanh().
      - Gamma family: hlo_lgamma(), hlo_digamma(), hlo_polygamma().
      - Error / Bessel / misc: hlo_erf(), hlo_erfc(), hlo_erf_inv(),
        hlo_bessel_i1e(), hlo_square().
      - Float predicates: hlo_is_inf(), hlo_is_pos_inf(),
        hlo_is_neg_inf().
      - Selection: hlo_top_k() returning the top-k values and their
        indices along the last dimension.
  - OpName() and new_Op() gain a dialect argument (default "stablehlo")
    to support ops from other MLIR dialects.

Bug fixes

  - hlo_reduce_window() now works on rank-1 inputs.

                        Changes in version 0.2.0                        

Features

  - Added support for Modules

Bug fixes

  - Constants +-Inf/NaN of dtype f64 are now correctly created.
  - Fixed assembly format for select op with all boolean (i1) types.

Miscellaneous

  - Use a simpler StableHLO string format for improved readability
