Changelog for string-interpolate-0.3.0.2

CHANGELOG

Removed upper bounds on base16-bytestring. Safe to do so now that text-converions has added upper bounds. This change should not affect any users of string-interpolate.

Downgraded version of base16-bytestring to avoid breaking API changes in new versions. (We would just upgrade the version ourselves, but it's one of our dependencies text-conversions that's not building due to the API changes, not us.)

Changed the behavior of iii to only collapse statically-available whitespace, which also removes the performance penalty of using iii.
Removed noise on compile errors if quasiquoters are misused
Changed behavior of backslash escapes to error on unknown escape characters

Added __i interpolator for stripping indentation in multiline strings
Added benchmarks for lazy Text and lazy ByteString
Changed default behavior for Text and ByteString to use the actual types themselves as intermediate objects rather than construct Builders. This should give significant speedups in the common case of interpolating smaller outputs. Old behavior can be reenabled using Cabal flags -ftext-builder and -fbytestring-builder
Gated benchmarks for Interpolation and interpolatedstring-perl6 behind a Cabal flag so that we can still be in Stackage without needing to remove these dependencies

Commented out interpolatedstring-perl6 benchmarks, since that library does not build on GHC 8.8.2

Updated interpolation parser to use enabled language extensions (Thanks Cary Robbins!)

Fixed bug caused when escaping a backslash right before an interpolation (Thanks Vladimir Stepchenko!)
Fixed behavior of iii (Thanks Vladimir Stepchenko!)
