1.2.6

• Increased upper-bounds of aeson to < 0.10 and of attoparsec to < 0.14.

1.2.5

• Increased the upper-bound of base to allow < 4.9. Now builds on GHC 7.10.1.

1.2.4

• Add a 100ms delay in the WebSocket upgrade process. This matches the behavior of the reference engine.io implementation (in NodeJS), and avoids a race condition on slower machines. Without this, it was possible for the client to experience a up-to-45s delay before upgrading.

1.2.3

• Revert double-encoding introduced in 1.0.1. This now requires that you use a modern version of the socket.io client library. This work was tested against socket.io-1.2.1.js.

1.2.2

• We now use stm-delay to implement a timeout, if we don't receive network traffic from the client. Under normal operation, the Socket.io client should ping the server, so an idle session should remain alive.

1.2.1

• Fixed a potential race condition in session allocation, where we could clobber existing session ids.

1.2.0

• ServerAPI's srvParseParseRequestBody has changed its return type to Either String a. This allows API providers to catch exceptions that may happen when attempting to perform this parse.

1.1.2

• 1.1.1 accidently removed websockets from the list of available upgrades. This release reverts that change.

1.1.1

• Long-polling connections now emit a ping message after 45 seconds, if no data is written to them.

• There is a new dupRawReader function, which lets you create a read-only stream of raw communication with a socket.

1.1.0

• The ServerAPI functions srvWriteBuilder, srvSetContentType and srvSetResponseCode have been merged into a single function: srvTerminateWithResponse. This should allow ServerAPI to be provided for Yesod.

  Thanks to Tim Baumann (@timjb) for this change.

1.0.2

• The ping thread spawned by websockets is now disabled, as it has been observed that these pings are using invalid sockets. Specifically, see https://github.com/lpsmith/postgresql-simple/issues/117.

1.0.1

• Purposefully double-encode websocket traffic. Unfortunately this is necessary due to https://github.com/Automattic/engine.io-client/issues/322. When a new version of engine.io is released upstream, I will revert this.

1.0.0

• Initial release
