Facebook for Windows Phone is about to get a big update, according to its developers.

Details of the next version (v2.5) of the social networking app for Microsoft's mobile platform have been published in a Facebook post.

"The team has been working hard over the past few weeks on building the next version of Facebook for Windows Phone," says the team behind the app.

The new update will bring even more features than the rather large update that the app has seen already this year.

Facebook v2.5 will bring:

- Threaded messaging: Full Facebook threaded messaging including group messaging, all in a beautiful Metro style design.

- Tagging: Now you can tag friends and locations in your posts in the "with" and "at" format.

- Delete posts and comments: Use the tap and hold context menu to delete posts and comments from your wall.

- Active links in posts: Tap on links in posts to go directly to the content.

- Updates to the photo comments and likes page: The photo comments and likes page has been updated to match the posts comments and likes page. You can see a hint of the image at the top of the page, pull down and you can see the whole thing.

- You can now "like" comments!

The developers say the app is going through the final rounds of testing before being released.
