python-qrcode v3.1 Release Notes
Release Date: 2013-08-12 // over 10 years ago-
🛠 Important fixes for incorrect matches of the alpha-numeric encoding mode. Previously, the pattern would match if a single line was alpha-numeric only (even if others wern't). Also, the two characters
{and}had snuck in as valid characters. Thanks to Eran Tromer for the report and fix.⚡️ Optimized chunking -- if the parts of the data stream can be encoded more efficiently, the data will be split into chunks of the most efficient modes.
