th-printf v0.7.0 Release Notes

Release Date: 2019-09-12 // over 2 years ago
    • 🆕 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 packing the result, especially with Text format arguments.
    • ⬇️ Dropped support for GHC < 8.
