Change: Directives specified in the client block can now only be inherited by explicitly declared location blocks within that block, so they don't affect the configuration of other modules that implicitly use the client block for outgoing requests.
Feature: Support for multiple client blocks allows common settings for different location blocks to be grouped within each block, which mitigates configuration duplication.
Bugfix: When the reuseport parameter was used in the listen directive, all connections to the specified address and port were handled by a single worker process; the bug had appeared in version 1.10.0.
Bugfix: An HTTP/3 handshake with an upstream server might fail with OpenSSL library version 3.5.0 or later if the QUIC protocol retry mode was active on the server.
Bugfix: Building the HTTP/2 and HTTP/3 modules using GCC 15 resulted in an error.
Bugfix: Building with the -O3 flag could result in an error when using GCC.
