-Release 5.6-alpha1
+Release 5.6 ALPHA1
 ------------------
 
+This is the first ALPHA release in the 5.6 release series. It adds several features
+such as transport content decompression and content compression for the async transport,
+support for Unix sockets, experimental support for SCRAM-SHA-256 authentication scheme,
+and Micrometer/OTel observations & metrics.
+
+Commons Compress, Brotli codec, and ZStd codec are optional dependencies and get
+wired into the execution pipeline only if present on the classpath.
+
+
+Notable changes and features included in the 5.6 series:
+
+* Unix domain socket support.
+
+* Support for pluggable content codecs via Commons-Compress in the classic transport.
+  (optional).
+
+* Support for transparent content decompression and content compression with `deflate`,
+  `gzip`, `zstd` (optional), and `brotli` (optional) codecs in the async transport.
+
+* Micrometer/OTel observations & metrics (optinal).
+
+* Off-lock connection disposal by the classic pooling connection manager. Experimental.
+
+* SCRAM-SHA-256 authentication scheme (RFC 7804), Experimental.
+
+
+Compatibility notes:
+
+* As of this version, HttpClient uses BUILTIN HostnameVerificationPolicy by default, delegating
+  host verification to JSSE security manager. One must explicitly configure the TLS strategy
+  to continue using the hostname verifier shipped with HttpClient.
+
+* Five-second TCP keep-alive is now enabled by default.
