Version 0.2.2

This release has no changed behaviors.

Upgraded dependencies:

• time to 0.3
• digest, sha2 and blake2 to 0.10
• base64 to 0.20
• clap to 3
• (benchmark only) criterion to 0.4

Also includes code cleanup/formatting. Code now passes clippy and is formatted with rustfmt.

Version 0.2.0

This version modifies the path handling behavior. Commands do not automatically add the extension .json.gz to any paths. This means that if you want to add these extensions, you must now do so when you invoke ick:

ick build db.json.gz path

(And so on.)
