Step 1 - Copy the content of zip file over the files in your Joomla  directory.

Step 2 - (needs to be done once) replace #_ in the following SQL queries with your data base prefix and run those on Joomla's database. This step needs to be done only once. Skip it if you upgrading from a previous version.

Create a table to store k2 multi category refferences

CREATE TABLE IF NOT EXISTS `#__k2_items_category_ref` (
  `catid` int(11) NOT NULL,
  `itemid` int(11) NOT NULL,
  PRIMARY KEY (`catid`,`itemid`),
  KEY `catid` (`catid`),
  KEY `itemid` (`itemid`)

Run the following SQL query to copy existing categories references into the new table:

INSERT INTO #__k2_items_category_ref (itemid, catid)
SELECT, c.catid FROM #__k2_items c;

Note: you will need to replace #_ with the prefix used in your Joomla install.

Step 3 - update your language file

You will also need to add the following lines to your language file(s) (ie administrator/language/overrides/en-GB.override.ini).

K2_PLEASE_SELECT_A_MULTI_CATEGORY="Please select at least one category"
K2_CATEGORY_MULTI="Multiple Categories"
K2_MULTI_CATEGORY_LEGACY_MESG="This option is used for extra field support and by modules that rely on a single category selection."

You are done!
