+# cloudflare-ddns v2.1.2 — Notification & Domain Casing Fixes
+
+This patch release fixes three bugs reported on GitHub.
+
+## Bug fixes
+
+- **Mixed-case domains now match existing DNS records (#255).**
+  In env-var mode, configuring a domain with mixed casing (for example
+  `ExaMple.com`) caused every update cycle to attempt a duplicate record
+  create and fail with Cloudflare error `81058: An identical record already
+  exists.` Cloudflare normalizes record names to lowercase server-side, so
+  the lookup is now case-insensitive.
+
+- **Pushover notifications work again (#258).**
+  The shoutrrr-style URL `pushover://shoutrrr:TOKEN@USER` (the canonical form
+  from `containrrr/shoutrrr`) was being parsed with the literal `shoutrrr:`
+  username included in the API token, which Pushover rejected. The parser
+  now strips the optional `<user>:` prefix from the token segment, restoring
+  the v2.0.7 behavior. Optional shoutrrr query parameters (`?devices=...`,
+  `?priority=...`) are tolerated.
+
+- **Gotify notifications now produce a valid request URL (#262).**
+  The Gotify URL parser blindly appended `/message` after any query string,
+  producing malformed webhook URLs like
+  `https://host:9090?token=XYZ/message`. The parser now follows shoutrrr's
+  canonical layout — token as the final path segment or `?token=` query —
+  and supports `?disabletls=yes` to switch the resulting webhook from HTTPS
+  to HTTP for typical home-LAN setups, plus the `gotify+http://` /
+  `gotify+https://` aliases.
+
+## Already addressed (closing #257)
+
+The robust public-IP discovery enhancements requested in #257 (multi-endpoint
+trace fallback, strict address-family validation, API request timeouts,
+duplicate record cleanup) were already folded into the Rust port shipped in
+v2.0.8 — see `src/provider.rs` (`CF_TRACE_PRIMARY` / `CF_TRACE_FALLBACK`,
+`validate_detected_ip`, `build_split_client`) and `src/cloudflare.rs`
+(`set_ips` dedup behavior, per-request `timeout`).
+
+## Upgrade
+
+```bash
+docker pull timothyjmiller/cloudflare-ddns:2.1.2
+# or
+docker pull timothyjmiller/cloudflare-ddns:latest
+```
+
+No configuration changes are required.
