Release 5.2.1 ------------------ This is a maintenance release that fixes several regressions found in release 5.2. Change Log ------------------- * Regression: Async execution runtimes set the negotiated protocol version in the execution context at the wrong point of request execution. Contributed by Oleg Kalnichevski <olegk at apache.org> * Cancel connection request on exception. Contributed by Bryan Keller <bryanck at gmail.com> * Replace deprecated use of LangUtils#equals() with Objects.equals(). Contributed by Gary Gregory <ggregory at apache.org> * Regression: Multipart body builder and multipart formatters fail to escape special characters such as backslash and quote mark. Contributed by Oleg Kalnichevski <olegk at apache.org> Release 5.2 ------------------ This is the first GA release in the 5.2 release series. This release finalizes the 5.2 APIs and corrects a number of defects discovered since the previous release. Please note that 5.2 upgrades the minimal JRE level to version 8 (8u251 is required). Please note this is likely to be the last release series with support for SPNEGO and NTLM authentication. As of version 5.3 GSS-API-based authentication schemes (Kerberos, SPNEGO) and NTLM authentication schemes are going to be deprecated and disabled by default. Notable changes and features included in the 5.2 series: * Upgrade to Java 8. * Improved support for TLS upgrade and HTTP protocol upgrade (async). * Support for H2 tunneling via HTTP/1.1 proxy. * Conformance to RFC 7617 (The 'Basic' HTTP Authentication Scheme). * Migration to Java 8 Time primitives in State Management and Cache APIs. * Connection and TLS configuration on a per route basis. * Base64 codec based on Commons Codec replaced with JRE Base64 codec. Dependency on Commons Codec dropped. * Optional support for BR (Brotli) decompression. Change Log ------------------- * HTTPCLIENT-2242: RoutingSupport fails to copy InetAddress when normalizing HttpHost. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2240: Fixed incorrect CONNECT method initialization in ProxyClient. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2236: MultihomeIOSessionRequester fails to enhance the cause exception in case of connect failure if the remoteAddress argument has been given. Contributed by Oleg Kalnichevski <olegk at apache.org> * Use Objects.toString() instead of String type cast Contributed by Gary Gregory <garydgregory at gmail.com> * HTTPCLIENT-2232: Last protocol interceptors moved at the end of the H2 protocol processing pipeline. Contributed by Oleg Kalnichevski <olegk at apache.org> * H2 async runtime to proactively set HTTP/2 protocol version in the execution context. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2231: Fixed a race condition in the main async executor when the request execution on an I/O thread is faster than execution pipeline management on the client thread. Contributed by Oleg Kalnichevski <olegk at apache.org> * Avoid duplicate redundant objects and use Singleton instead. Contributed by Arturo Bernal <arturobernalg at gmail.com> * HTTPCLIENT-2225: Connection route calculation does not take the default RequestConfig into account. Contributed by Oleg Kalnichevski <olegk at apache.org> * Avoid unnecessary use of Instant.toEpochMilli by using Instant#compareTo to compare Instants directly. Contributed by jkmcl * HTTPCLIENT-2221 Closing a classic response/entity allows connection reuse. Contributed by Carter Kozak <ckozak at apache.org> Release 5.2 BETA1 ------------------ This is the first BETA release in the 5.2 release series that upgrades minimal JRE level to version 8 (8u251 is required) and includes several protocol level and API improvements. It also includes all bug fixes from the 5.1 branch. Change Log ------------------- * Upgraded HttpCore to version 5.2-beta2. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2218: Use Java 8 Base64 utility (#370).

Contributed by Anthony Baldocchi <489445+ajbaldocchi at users.noreply.github.com> * Fixed infinite recursion in SSLConnectionSocketFactory. Contributed by Ryan Schmitt <rschmitt at apache.org> * HTTPCLIENT-2200: Protocol interceptors are executed before the connection route has been fully established. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2209: Pass HttpContext to AsyncClientConnectionOperator (#353). Contributed by Andriy Redko <drreta at gmail.com> * HTTPCLIENT-2206: Corrected resource de-allocation by fluent response objects. Contributed by Oleg Kalnichevski <olegk at apache.org> * ExecSupport#getNextExchangeId() optimization (#352) Contributed by David Schlosnagle <schlosna at gmail.com> * HTTPCLIENT-2203: Corrected target host normalization by the request execution interceptors; added ContextBuilder with support for preemptive authentication initialization.

Contributed by Andrei Vasilev <59628447+AndreiSVasilev at users.noreply.github.com> * Updated AbstractClientTlsStrategy to pass only the HttpVersionPolicy set by TlsConfig instead of the entire TlsConfig to H2TlsSupport#selectApplicationProtocols() method. Contributed by Andrei Vasilev <59628447+AndreiSVasilev at users.noreply.github.com> * HTTPCLIENT-2195, regression: Classic ConnectExec incorrectly discards the proxy response body even if the request cannot be executed and the response is final. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2194: Async retry request interceptor fails to correct include request body on retry (#343). Contributed by JasonMathison <JasonMathison at users.noreply.github.com> * Deprecated execute methods that return an open response object in favor of execute methods with a response handler and automatic resource deallocation. Contributed by Oleg Kalnichevski <olegk at apache.org> * HTTPCLIENT-2189: Cookie and Cache APIs to use Java time primitives. Contributed by Arturo Bernal <arturobernalg at gmail.com> * Apply English locale to all date header formatters.
