The much-maligned feature was first introduced in 2016, but under the new changes, Twitter users will now revert timelines to a non-algorithmic, reverse-chronological order - which is how the site worked in its original guise.
In a series of statements, the company explained: "1/ We're working on new ways to give you more control over your timeline. But first, some context: Twitter helps you see what's happening by showing the best Tweets for you based on your interactions.
"2/ We've learned that when showing the best Tweets first, people find Twitter more relevant and useful. However, we've heard feedback from people who at times prefer to see the most recent Tweets.
"3/ Our goal with the timeline is to balance showing you the most recent Tweets with the best Tweets you're likely to care about, but we don't always get this balance right.
"4/ So, we're working on providing you with an easily accessible way to switch between a timeline of Tweets that are most relevant for you and a timeline of the latest Tweets. You'll see us test this in the coming weeks.
"5/ Meanwhile, today we updated the "Show the best Tweets first" setting. When off, you'll only see Tweets from people you follow in reverse chronological order. Previously when turned off, you'd also see "In case you missed it" and recommended Tweets from people you don't follow. (sic)"
