*New users need no extra steps.
Just download and start your new OK wallet to start using the software.

*Users with previous wallets.
How to update:

This update requires a change in the database structure to open the new features, needs to resync.
(All your coins are safe of course)

1.- Delete old okcash-qt.exe clients and download the new okcash v3 client. ( Zip or Installer)

2.- Go to your okcash data folder at:

Windows:
C:\Users\UserName\Appdata\Roaming\OKCash

Mac OS:
~/Library/Application Support/OKCash/

Linux:
~/.okcash/

Make a backup of your "wallet.dat" file, and delete all the other files in this folder except for "wallet.dat"

3.- Install or unzip your new okcash v3 client and it will start to sync.

4.- For faster sync you can download a bootstrap file at:
http://bit.ly/OKbootstrap
unzip and place it into the okcash data folder before starting the v3 client.
(It will take around 2 hours for the wallet to reindex the blocks from the bootstrap, it may seem unresponsive but give it some time and it will finish its work loading the chain)

v3 Mac OSX clients to be released in the coming days*

HTML5 upgrade from Shadowcoin Tech. In wallet HTML5 Framework.

HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It was finalized, and published, on 28 October 2014 by the World Wide Web Consortium (W3C). This is the fifth revision of the HTML standard since the inception of the World Wide Web. The previous version, HTML 4, was standardized in 1997.

Its core aims are to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.

BIP32 upgrade from Bitcoin Tech. Hierarchical Deterministic (HD) key creation and transfer protocol (BIP32).

A deterministic wallet is a system of deriving keys from a single starting point known as a seed. The seed allows a user to easily back up and restore a wallet without needing any other information and can in some cases allow the creation of public addresses without the knowledge of the private key.
