Twitter has finally begun rolling out its long-awaited edit button after months of beta testing.

The new feature, which gives users the ability to edit their own published tweets within a 30-minute window, is limited to Twitter Blue subscribers for now.

Twitter’s premium subscription service is currently only available in the US, Canada, Australia and New Zealand – at a monthly cost of $4.99 / AU$4.49 – but is expected to launch in more countries in the near future.

Although the new edit button gives Twitter Blue users the option to rectify embarrassing mistakes, regular Twitter users can identify edited tweets through a handy ‘last edited’ label (which itself appears next to a bold pencil icon).

By clicking on this ‘last edited’ label, anyone can see a tweet’s edit history (i.e. what changes have been made, and when), which is presumably Twitter’s solution for maintaining transparency between paying and non-paying users.

The first edited tweet (see above) was sent by the company’s official Twitter Blue account. The original tweet read “this is a test to make sure the edit button works”, but was later edited to read “this is a test to make sure the edit button works, we’ll let you know how it goes”.

The former version of the tweet now bears a label reading “There’s a new version of this Tweet. See the latest Tweet” for clarity.

In addition to editable tweets, Twitter Blue offers subscribers more UI customization options, ad-free articles and the ability to undo tweets via a 60-second countdown timer.
