Release Notes

apache/httpcomponents-client (org.apache.httpcomponents.client5:httpclient5)

v5.6

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.

• Request Priority support (RFC 9218). 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.
