Changelog

Sourced from base64's changelog.

0.21.5

• Make encoded_len const, allowing the creation of arrays sized to encode compile-time-known data lengths

0.21.3

• Implement source instead of cause on Error types
• Roll back MSRV to 1.48.0 so Debian can continue to live in a time warp
• Slightly faster chunked encoding for short inputs
• Decrease binary size
