## 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
|
||||
|
||||
* Fix for/in used over array, causing glitches with augmented Array prototypes (thanks [pelikhan](https://github.com/pelikhan))
