Changes in 1.1.7:
- Fix bug in Content-Length calculation

Changes in 1.1.6:
- Use Import for dependency packages instead of Depends.
- `http_response` function now optionally takes custom headers.

Changes in 1.1.5:
- Signal an error when unable to bind socket listener (as opposed to failing
  silently).
- Fixed a bug where server socket could be inadvertently closed when an older
  socket was finalized by the gc.
- Added support for fragmented messages and control frames.
- Added support for ping/pong messages.
- Fix buggy interpretation of frame header.

Changes in 1.1.2--1.1.4:
- Added a function called 'daemonize' that services websockets from the main
  R event loop, returning control to the console. The previous method using
  an explicit blocking event loop also still works.

Changes in 1.1.1:
- Fixed a major bug affecting 64-bit Windows platforms.
- Checked build with R-2.14.0.
- Fixed minor check warning and note on some platforms.
- Expanded generic HTTP server capability.
- Added http_response and http_vars functions.
- Expanded vignette.

Significant changes in package version 1.1.0:
- We rebuilt the package from the ground-up, removing the dependency on the
  libwebsockets C library, and instead implementing the websockets protocol
  mostly in R.
- The older IETF-00 protocol supported by the previous package versions
  as well as newer protocols up to at least -15 are now supported.
- All features related to "cookies" have been removed. Sorry if this breaks
  something. It's easy enough to replicate that functionality directly in R.
- THE CALLBACK FUNCTIONS HAVE CHANGED: there are only three (established,
  receive, and closed) and their parameters are different. SEE THE set_callback
  HELP PAGE.
- Each websocket server has an R environment associated with it. The environment
  contains a list of connected client websockets and all other data required
  by the server.
- There are new functions for serving static web pages from files or strings.
- We added a websocket client function too.
- The license has changed from GPL-2 to LGPL-3.
