cloudflare-ddns v2.1.1

Maintenance release. Bug fix for rand 0.10 API change, plus opt-in failure-safe deletion behavior contributed in the v2.1.0 → v2.1.1 window, dependency refresh, and proportional jitter for IP detection.

Highlights

Fix: Restore the build under rand 0.10 — random_range moved to the RngExt trait, and the unconditional jitter sleep in --repeat mode no longer fails to compile.
New: DELETE_ON_FAILURE (env-var mode) controls whether DNS records are removed when an IP detection or update fails. Defaults to true to preserve existing behavior; set DELETE_ON_FAILURE=false to keep stale records on transient failures instead of yanking them.
Improvement: Proportional jitter (up to 20% of the update interval) is added before each scheduled update to spread requests across clients and reduce synchronized spikes against the Cloudflare API.

Changes since v2.1.0

Features

DELETE_ON_FAILURE env var to prevent DNS record deletion on failed updates (#263, thanks @DMaxter)
Proportional jitter on update intervals to desynchronize API traffic (#253, thanks @jhutchings1)

Fixes

Compile fix for rand 0.10: import RngExt so random_range resolves
delete_on_failure regression test coverage added

Dependencies

rustls 0.23.37 → 0.23.40
rustls-webpki 0.103.10 → 0.103.13
tokio 1.50.0 → 1.52.1

Document DELETE_ON_FAILURE in the README

Upgrade notes

Default behavior unchanged. DELETE_ON_FAILURE defaults to true, matching pre-2.1.1 behavior. Set it to false if you want stale records preserved during outages.
No config file schema changes. Existing config.json deployments continue to work without edits.
