CHANGELOG.md

Changelog

v0.7.24 - 2015-08-10

Adds DMD 2.068.0 compatibility and contains a number of additions and fixes in all parts of the library. Some notable changes are the addition of WebSocket support in the vibe.web.web module and the planned deprecation of opDispatch for Json and Bson, as well as the rename of all "SSL" symbols to "TLS". HTTP request handlers can, and should, now take the request/response parameters as scope, which will later allow to improve performance without compromising safety.

Features and improvements

• Web interface generator (vibe.web.web)
  • Added support for WebSocket routes - issue #952
  • Doesn't intercept HTTPStatusExceptions thrown during parameter assembly anymore
