cloudflare-ddns v2.2.0 — Zulip Notifications, Safer Failure Handling & Helm Chart

This minor release adds new notification and deployment options, a safer default when IP detection fails, and a stable IPv6 provider for Linux hosts.

⚠️ Behavior change: `DELETE_ON_FAILURE` now defaults to `false` (#277)

Previously, when a provider definitively reported no address for an IP family, managed DNS records for that family were deleted by default — which could take services offline after a transient misdetection.

DELETE_ON_FAILURE now defaults to false: on detection failure the update is skipped and existing records are preserved.
Transient detection errors (network failures) always preserve existing records, regardless of this setting.
WAF list updates are now skipped when any configured IP family fails detection, preventing a partial failure from silently stripping that family's IPs from the list.

If you relied on the old behavior, set DELETE_ON_FAILURE=true explicitly.

New features

Zulip notifications (#271). Native zulip:// shoutrrr URL support:
```
zulip://bot-mail:bot-key@host/?stream=stream-name&topic=topic-name
```
Messages are sent to the Zulip API (/api/v1/messages) with Basic auth. The @ in the bot email may be written literally or percent-encoded (%40); topic is optional and defaults to Cloudflare DDNS.
Configurable JSON field for generic webhooks (#271). Generic webhooks send {"message": "..."} by default. Append ?messagekey=<field> to rename the field — e.g. generic://host/path?messagekey=text for services expecting Slack-style payloads (including Zulip's slack-compatible endpoints).
Stable local IPv6 provider (#273). New local.iface.stable:<name> provider selects the preferred stable IPv6 address from a Linux network interface, excluding temporary (privacy-extension) and deprecated addresses.
Helm chart (#278). A Helm chart is now available under charts/cloudflare-ddns, published as an OCI artifact to GHCR via CI.

Dependency updates

reqwest 0.13.4, rustls 0.23.42, tokio 1.52.4, rand 0.10.2, serde_json 1.0.150, actions/checkout 7

Upgrade

docker pull timothyjmiller/cloudflare-ddns:2.2.0
# or
docker pull timothyjmiller/cloudflare-ddns:latest

No configuration changes are required unless you depend on records being deleted when IP detection fails — in that case set DELETE_ON_FAILURE=true.
