CHANGELOG

v0.5.0

Support Python 3.12 and 3.13.
Speed up encoding by ~85% by optimizing blocklist checks (PR #23, thanks to @kurtmckee). This improvement requires more calculation when the Sqids class is instantiated, so users are encouraged to instantiate Sqids once and always reuse the instance.

v0.4.1

Compatibility with Python 3.6 (not officially supported)

v0.4.0

Use double underscore convention to specify private methods
Separate single module into a package for better readability
Add PEP 561 compatible type hints

v0.3.0: ⚠️ BREAKING CHANGE

min_length upper limit has increased from alphabet length to 255
Max blocklist re-encoding attempts has been capped at the length of the alphabet - 1
Minimum alphabet length has changed from 5 to 3
min_value() and max_value() functions have been removed
Max integer encoding value is sys.maxsize
