Debug

Known issues

breakingThe API changed between 0.2.x and 0.3.x: `compress()` now returns bytes instead of a tuple. Check your code if upgrading from older versions.

fix

If you used `(compressed, length) = compress(data)`, change to `compressed = compress(data)`.

affects: <0.3

gotchaCompression on empty bytes returns empty bytes. Not an error, but be aware.

fix

Handle empty input explicitly if needed.

affects: all

gotchaIf input is not bytes, TypeError may be raised. Always pass bytes objects.

fix

Use `.encode()` on strings: `compress(my_string.encode())`.

affects: all
