v0.15 alpha 1

• At this point the API is pretty much done.
• Autobahn tests pass, in SSL and non-SSL but many parts of WebSocket support is missing.
• Windows and Linux has been tested, it should compile and run on both platforms.
• Performance is very good, reaching 130% that of v0.14.
• This is not production ready code, it is completely broken at points.

v0.14.8

Features & fixes:

• New permessage-deflate option uWS::SLIDING_DEFLATE_WINDOW for improving compression ratio of small messages. This option is very memory costly and not recommended.
• Disallow sending control frames compressed.
• We do no longer accept server_no_context_takeover as we do not listen to it anyways.

v0.14.7

Features & fixes:

• Initial permessage-deflate send compression support is now exposed as bool compress argument in WebSocket::send function.
• If given more than one websocket subprotocol at upgrade, select the first one and continue.

v0.14.6

• New minimal front page
• Links to a draft at a user manual
• Hub::poll as alternative to Hub::run for busy-waiting
• Classes are protected rather than private to allow derivatives
• Some warnings fixed
• Hub::connect hostname:port fixes
• Fixes for newer Boost versions

v0.14.5

• Timer and similar things now live in uS namespace

v0.14.4

• Fixes to Hub::connect URI parser, esp. IPv6 addresses.
• Do not emit connection error more than once.

v0.14.3

• Configurable maxPayload option
• Properly handle connection errors

v0.14.2

• Epoll timer fixes.
• Clear pending async poll changes on socket removal.
• Updated multithreading example with reuseport.
• Limit extension and subprotocol lengths.

v0.14.1

Placeholder tag to even out version mismatch between GitHub and NPM. Same commit as v0.14.0.

v0.14.0

This release is a major internal refactor and redesign aimed at C++ programmers specifically.

Features

• Adds support for multiple event systems (libuv, ASIO & epoll).
• Highly optimized memory usage - 37% of prior version 0.13.0.
• Optimized parser and control frame receive paths - 4-8x the performance.
• Optional thread safety of documented functions (compile with UWS_THREADSAFE).
• Hub::connect now takes optional headers such as origin.
• Removes CMake, improves native Makefile, adds native VC++.vcxproj.
• Adds onTransfer callback.
• Mingw64 compiler support.

Fixes

• Sets SOCK_CLOEXEC on Linux and FreeBSD.
• Properly handles WSAEWOULDBLOCK on Windows.
• Memory leaks on send errors.
• Parser crash on very long messages.
• Travis CI now runs all native tests with every commit.
• Removes Node.js addon from main repository, it now lives in bindings repo.

Interface changes

• In prior versions a WebSocket could be represented by a void pointer, an uv_poll_t pointer or a WebSocket object. This kind of chameleon black magic is removed and there is now only WebSocket pointers in use.
• WebSockets are handed out as pointers in all event handlers.
• Send callbacks now give a pointer to a WebSocket rather than a void pointer.
• There is no longer any getPollHandle() and you cannot construct a WebSocket from an uv_poll_t pointer.
• Lots of encapsulation fixes, most structs are now exposing only the official API and not its internals.
• uWS::Group::listen(uWS::TRANSFERS) is a new way to express uWS::Group::addAsync().
