Change "new discussion" label in a SharePoint Discussion Board

It is unfortunately not possible to change the "+ new discussion" label out of the box. This wouldn't be a problem if you use this app only as a discussion board. What if you want to have an advanced "News"-Stream, where the readers must be able to comment the news? Or an eBay-like marketplace? Therefore, a "new discussion" wouln't be appropriate, it has to be something like "Create News" or "New Offer".

Herefore you can change the label using JavaScript. Insert a script editor webpart into the Category.aspx page and use following script:

	//self-executing anonymous function
	(function () {
	// String overrides
	function DiscussionListViewStringOverride() {
	Strings.STS.L_SPDiscHeroLinkAltText = "New Label"; //change "New Label" into your desired one, eg. "Create News"
	Strings.STS.L_SPDiscHeroLinkFormat = "New Label"; //change "New Label" into your desired one, eg. "Create News"
	}
	DiscussionListViewStringOverride();
	ExecuteOrDelayUntilScriptLoaded(DiscussionListViewStringOverride, "strings.js");
	})();

This script was tested with SharePoint 2013 and SharePoint 2016.
