v1.2.0

Added checking the current public address against your active DNS record, to avoid hitting HE's servers more than necessary. Also massively updated dependencies, moving off of the ancient prerelease version of Tokio this application was using.

This now marks several years of it successfully keeping my network updated with no intervention, however, so that's pretty fantastic.

Stable with Interfaces

Now the tool uses a combination of interface and record type to build the client for each update, which clarifies handling IPv6 addresses. Future support for TXT records will need to be sorted out; I haven't decided on an approach to that just yet.

Initial stable release

The tool successfully achieves the goal of updating DDNS records in Hurricane Electric's DNS, can be run automatically with systemd, and the core logic has tests in place. Documentation is available, and several examples are on hand.
