Twitter has announced that it is making some changes to its 140 character limit, the maximum characters in a tweet will still be 140 characters, but some things no longer count towards this limit.
For example when you reply to someone, like @GeekyGadgets, the @name will no longer count to 140 characters.
Also media attachments like videos, Gifs, polls and more will no longer count, the same goes if you quote someones tweet
Twitter are also enabling the the Retweet button on your own tweets, this allows you to easily quote or Retweet yourself.
These updates will be available over the coming months. Today, we’re notifying you and our developers, so that everything works as it should when we roll these changes out. The updates have a significant impact on Tweets, so we want to provide our developer partners with time to make any needed updates to the hundreds of thousands of products built using Twitter’s API.
In addition to the changes outlined above, we have plans to help you get even more from your Tweets. We’re exploring ways to make existing uses easier and enable new ones, all without compromising the unique brevity and speed that make Twitter the best place for live commentary, connections, and conversations.
Twitter has said that these updates will be released over the next few months, you can find out more details at the link below.
