Release Notes

benoitc/hackney (hackney)

v3.1.0

Compare Source

Refactor

• Replace QUIC NIF with pure Erlang implementation. HTTP/3 now works with zero external dependencies - no CMake, Go, or C compiler needed. Just rebar3 compile.

Removed

• Remove c_src/ directory containing lsquic, BoringSSL, and NIF code (~1.3M lines of C)
• Remove do_cmake.sh and do_quic.sh build scripts

Added

• Add hackney_qpack.erl for QPACK header compression (RFC 9204)

Changed

• hackney_quic:is_available/0 now always returns true (pure Erlang is always available)
• Update documentation to reflect no C dependencies

Dependencies

• Add quic ~>0.5.1 (pure Erlang QUIC implementation)

v3.0.3

Compare Source

Bug Fixes

• Restore function-based streaming body support (#​821). Functions passed to send_body/2 now work correctly for iterative body streaming, supporting both stateless fun() -> {ok, Data} | eof and stateful fun(State) -> {ok, Data, NewState} | eof forms.

CI

• Fix FreeBSD CI job by adding pcre2 package to resolve git linker error

v3.0.2

Compare Source

Bug Fixes

• Add default Content-Type: application/octet-stream header when sending a body without explicit Content-Type (#​823). This restores 1.x behavior and follows RFC 7231 recommendations.

Dependencies

• Bump certifi to 2.16.0 (#​824)
