v2.1.1 - rand 0.10 fix + failure-safe delete + jitter

on GitHub

Maintenance release. Bug fix for rand 0.10 API change, plus opt-in failure-safe deletion behavior, 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
• reqwest 0.13.2 → 0.13.3
• rand 0.9.2 → 0.10.1

Docs

• Document DELETE_ON_FAILURE in the README

Upgrade notes

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