| AXIS2C-1707 | Add HTTP/2 transport support for JSON requests |
| AXIS2C-1708 | Modern security hardening |
The following features have been removed in version 2.0.0 as part of security hardening (AXIS2C-1708) and deprecation cleanup:
NTLM Authentication (--enable-heimdal, --enable-libntlm): Removed due to critical security vulnerabilities including pass-the-hash attacks, NTLM relay attacks, and weak cryptography. Microsoft is deprecating NTLM in Windows systems. Use Kerberos, OAuth 2.0, or mutual TLS instead.
TCP Transport (--enable-tcp): Obsolete transport that lacks HTTP semantics (no Content-Length, chunked encoding, headers, status codes). Incompatible with TLS (requires HTTP for ALPN negotiation) and web infrastructure (proxies, load balancers, firewalls expect HTTP). Use HTTP/2 instead, which provides multiplexing benefits with full HTTP semantics.
CGI Transport (--enable-cgi): Obsolete deployment model with security concerns and performance overhead of process-per-request. Use mod_axis2 with Apache httpd instead.
libcurl HTTP Backend (--enable-libcurl): Redundant with native HTTP client implementation. MTOM was broken with libcurl (AXIS2C-1270). HTTP/2 support uses nghttp2 instead.
AMQP Transport (--with-qpid): Unmaintained since 2010. Apache Qpid C++ is in maintenance mode. Modern messaging systems use REST APIs, gRPC, or native AMQP 1.0 clients. (AXIS2C-1641)
IIS/ISAPI Integration: Unmaintained since 2009. Windows users should use WSL2 with Apache httpd instead.
SSL/TLS Peer Validation: SSL/TLS peer name validation is now enabled by default (AXIS2C-1700). Applications that previously connected to servers with invalid certificates will now fail. To restore the old behavior (not recommended), disable peer verification in your SSL configuration.
NTLM Authentication Removed: Applications using NTLM authentication must migrate to Kerberos (for Windows/AD environments), OAuth 2.0/OpenID Connect (for modern applications), or mutual TLS (for service-to-service communication).
TCP Transport Removed: Applications using raw TCP transport (AXIS2_TRANSPORT_TCP) must migrate to HTTP/1.1 or HTTP/2 transport. HTTP/2 provides similar multiplexing benefits with full HTTP semantics and TLS support.
CGI Deployment Removed: Applications deployed via CGI must migrate to mod_axis2 with Apache httpd or the standalone axis2_http_server.
libcurl Backend Removed: Applications that explicitly enabled libcurl (--enable-libcurl) will now use the native HTTP client. This should be transparent for most use cases.
AMQP Transport Removed: Applications using AMQP transport must migrate to alternative messaging solutions or REST-based APIs.
IIS Support Removed: Applications using IIS integration must migrate to Apache httpd (running natively or via WSL2 on Windows).
