 ### 7.8-SNAPSHOT
 
 #### Bugs
+* Fix #7947: (kubernetes-client-api) Basic proxy credentials are decoded by splitting on the first colon only, preserving passwords that contain colons and preventing Jetty and Vert.x proxy auth from falling back to origin request headers
 * Fix #7953: (httpclient-jdk) bodyless requests now preserve the requested HTTP method instead of silently defaulting to `GET`. `JdkHttpClientImpl.requestBuilder` only called `HttpRequest.Builder.method(...)` inside the `body != null` branch, so a bodyless `DELETE`/`POST`/`PUT`/`PATCH` (such as `client.raw(uri, "DELETE", null)`) was sent as `GET` on the JDK backend; the method is now set with `BodyPublishers.noBody()` when there is no body, matching the OkHttp, Jetty and Vert.x backends
 * Fix #7435: (kubernetes-client) A `SharedIndexInformer`'s periodic resync no longer stops permanently and silently when a single resync cycle throws. `DefaultSharedIndexInformer.scheduleResync` runs the resync through `Utils.scheduleAtFixedRate`, whose self-rescheduling chain re-arms the next cycle only when the previous one completes normally; an uncaught exception completed the (unobserved) `resyncFuture` exceptionally and the resync was never scheduled again, with no log, while the independent watch kept `isWatching()` reporting `true` (a restart was required to recover). The resync command now catches and `WARN`-logs the failure so the schedule fires again at the next interval
 * Fix #7933: (kubernetes-client-api) Deterministic TLS trust failures (untrusted cert, expired cert, hostname mismatch) are now classified as terminal and fail fast instead of being retried by the shared `StandardHttpClient.shouldRetry` backoff loop (~19 s drain). The classifier walks both `getCause()` and `getSuppressed()` trees for `CertificateException`, `CertPathValidatorException`, `CertPathBuilderException`, and `SSLPeerUnverifiedException`. Affects all five HTTP client modules (jdk, jetty, okhttp, vertx-4, vertx-5) on both the HTTP request and WebSocket connect paths
