Past versions

Feb 28th, 2019 https://libdill.org/libdill-2.14.tar.gz

• ipc_sendfd() and ipc_recvfd() functions added. They allow to send OS-level
  file descriptors to different processes via an IPC connection.
• Multiple bug fixes.

Oct 29th, 2018 https://libdill.org/libdill-2.13.tar.gz

• An implementation of Happy Eyeballs protocol (RFC 8305) added.
• Function ipaddr_remotes() added.
• A bug in resolving IPv6 addresses fixed.

Oct 18th, 2018 https://libdill.org/libdill-2.12.tar.gz

• A bug in TLS protocol fixed.
• A memory leak in HTTP protocol fixed.

Sept 23th, 2018 https://libdill.org/libdill-2.11.tar.gz

• Couple of OSX bugs fixed

Sept 16th, 2018 https://libdill.org/libdill-2.10.tar.gz

• C++ guards added to libdill.h
• Tutorials fixed

Jul 20th, 2018 https://libdill.org/libdill-2.9.tar.gz

• "fromfd" functions added allowing to wrap native OS sockets into lidill's socket classes.
• Couple of bug fixes.

Apr 27th, 2018 https://libdill.org/libdill-2.8.tar.gz

• hdone() function was removed and replaced by type-specific done functions (e.g. "chdone", "tcp_done").
• hdup() was replaced by hown() with different semantics (transfer of ownership).
• PFX protocol renamed to PREFIX.
• CRLF protocol renamed to SUFFIX, allows to sepcify arbitrary delimiter, not just CRLF.
• Terminal handshake removed from PREFIX and SUFFIX protocols.
• New protocol TERM added. It does terminal handshakes.
• EBUSY error if a socket is used from multiple coroutines in parallel.
• All the symbols exported from the library have "dill" prefix.
• Macros to expand raw names to dill-prefixed names (chsend -> dill_chsend).
• DILL_DISABLE_RAW_NAMES disables the raw name macros, prevents name clashes with different libraries.
• Funcion ipaddr_equal() added. Compares two IP addresses.
• Handle numbers are reused much more rarely.
• Many bugfixes.

Apr 1st, 2018 https://libdill.org/libdill-2.7.tar.gz

• All mem functions take a structure instead of a raw byte buffer
  • More compile-time safety checks
  • Alignment done by compiler rather than left to the user
• PFX protocol is parametrized
  • Customizable size of the 'size' field
  • Customizable endianness of the field
• Several bug fixes.

• Multiple bugfixes.
• Multiple performance enhancements.

Dec 16th, 2016 https://libdill.org/libdill-1.0.tar.gz
