The ability to edit Twitter posts has long been the most requested feature. At the beginning of April this year, Twitter finally confirmed that they are working on an editing feature.

The developer has now started testing the editing of posts internally and the function will be sent out to regular users later in September. Here's how it works: users can edit posts for up to half an hour after publication, for example to correct typos or add hashtags.

Edited posts will be marked with an icon and a label, so that it is visible that the text has been changed and when it was changed. A tap on the label shows edit history. In other words, it is possible to see all previous versions of the post.

It is not clear how the editing will affect posts embedded in websites. Likely to show the original post. One catch is that the editing function will only be released to Twitter Blue subscribers - at least initially.
