## History ## History
### 0.13.0
* Updated protocol version to support 1.8.1 (thanks [wtfaremyinitials](https://github.com/wtfaremyinitials))
* Lots of changes in how some formats are handled.
* Crypto now defaults to a pure-js library if URSA is missing, making the lib easier to use on windows.
* Fix a bug in yggdrasil handling of sessions, making reloading a session impossible (thanks [Frase](https://github.com/mrfrase3))
* Set noDelay on the TCP streams, making the bot a lot less laggy.
### 0.12.3 ### 0.12.3
* Fix for/in used over array, causing glitches with augmented Array prototypes (thanks [pelikhan](https://github.com/pelikhan)) * Fix for/in used over array, causing glitches with augmented Array prototypes (thanks [pelikhan](https://github.com/pelikhan))
