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.
