## 0.7.0 (2019-09-12)

* New `%Q` and `%q` format specifiers accept strict and lazy Text as input
  respectively. Otherwise they function identically to the `%s` specifier.
* th-printf can now produce lazy Text as well as String, and the improved
  internal representation of format strings should slightly increase performance.
  * Directly producing Text should now be significantly faster than using the 
    string formatter and `pack`ing the result, especially with Text format arguments.
* Dropped support for GHC < 8.

## 0.6.0 (2018-08-18)

Backported new backpack-based code to pre GHC-8.4 versions.

* Rename of public modules
* Parser rewrite
* th-printf now prints a warning when given an erroneous format string
* Several printf behaviors have been updated to comply with spec:
  * `x`, `u`, etc. specifiers now only apply to positive integers
  * Length specifiers are allowed
* Generated testsuite covers more cases
