2.0.0

Breaking changes:

• retry::Error is now a struct with public fields instead of an enum with a useless Internal variant. (See #38 and #42.)
• retry::delay::Exponential::from_millis now uses an exponential backoff factor of 2.0 instead of whatever the initial delay is. If you want the old behavior, use retry::delay::Exponential::from_millis_with_base_factor instead. (See #31.)

Improvements:

• The crate's documentation now uses Intra-rustdoc links for convenient navigation.

Fixes:

• Fixed a broken external link in the documentation.
