Changelog

v1.0.0 (2026-06-15)

The client and server implementations were separated into two distinct packages to improve modularity and maintainability.
A t() typespec was added to GRPC.Server.Adapters.ReportException to improve type documentation and tooling support.
IPv6 support was added to the gRPC gun adapter, enabling connections over IPv6 networks.
Virtual channels can now be explicitly named, allowing clearer identification and management of channels.
Support was added for grpc-web trailers encoded in the message body, improving compatibility with grpc-web clients.
The inbound gRPC deadline is now surfaced on GRPC.Server.Stream via the deadline field (absolute monotonic time in ms, or nil if no deadline was set) and the GRPC.Server.Stream.remaining_ms/1 helper function, enabling deadline budget propagation in interceptors and handlers.
application/json content-type matching in transcoding is now loosened to support additional content types with parameters.
Boolean query parameters are now correctly coerced to Elixir boolean types in transcoding.
Elixir 1.20 is now supported with updated dependency constraints.

Fixed an issue in stream map_error where send_response handling could behave incorrectly.
Resolved a persistent_term memory leak in GRPC.Client.Connection that occurred when a connection was disconnected.
Corrected the cacertfile option name.
Added detection of name collisions and introduced a fallback mechanism for the call function.
Fixed broken benchmark links in the project.
Resolved two compiler warnings/errors in grpc.
Ensured $callers are properly propagated in GRPC.Stream Flow workers.
Fixed address key generation in handle_info(:refresh) to correctly support Unix domain sockets.
Fixed an issue where buffers were not fully drained when a single HTTP/2 frame carried multiple gRPC messages.
Resolved a client disconnection handling issue.
Fixed type system warnings related to Elixir 1.19.
Fixed an error handling issue in stream map_error.
Corrected the connection state initialization created by build_direct_state.
Added a configurable request body size limit to prevent potential resource exhaustion.
Fixed path parameters to correctly take precedence over query parameters in HTTP transcoding.
Fixed unsafe binary_to_term decoding in the erlpack codec to block dangerous terms.
Fixed a zip bomb vulnerability in the gzip compressor.

Corrected documentation related to unary responses and added clarification about the adapter_opts.cred option.
