1.8.0

• feat(png.cr): add support for passing in IO memory or files directly by @stakach in #2

Full Changelog: 1.7.0...1.8.0

1.7.0

• Support Crystal 1.11.x
• Multithreading support
  • When the program is compiled with -Dpreview_mt flag, Goban will run the mask evaluation, which takes the longest, in parallel
  • The speedup is more obvious when the encoding data is not too short
  • Everything will work the same as before without the flag

❯ shards build --release -Dpreview_mt
Dependencies are satisfied
Building: qr_test

❯ CRYSTAL_WORKERS=4 ./bin/qr_test "A fast and efficient QR Code encoder/decoder library written purely in Crystal. It is significantly faster (4-10×) and uses fewer heap allocations (-95%) compared to the other implementation in Crystal (spider-gazelle/qr-code), and it supports wider QR Code standard features such as Kanji mode encoding. It also supports generating Micro QR Code and rMQR Code symbols."
