Twitter users can officially send one another direct messages topping 140 characters starting Wednesday.

Twitter is phasing in the change across Android, iOS and web-based platforms on Wednesday, lasting over the next few weeks. Instead of 140 characters, the social network previously said in June the new character maximum would be 10,000.

"You can now chat on (and on) in a single direct message, and likely still have some characters left over," the company wrote in a blog post published Wednesday.

Twitter also emphasized in the post that while direct messages can now run really, really long, tweets will still be subject to the same 140-character limit they've always been.

In recent months, Twitter has made numerous tweaks to the social network, including direct messages.

Twitter originally announced it would remove the 140-character limit from direct messages back in June, the same day former CEO Dick Costolo announced he would step down.

Direct messages have long played second fiddle to tweets, but in recent months, Twitter has tried to broaden its appeal to more people, enabling group messaging in January and allowing users to receive direct messages from anyone on the network — just by checking an option in settings — beginning in April.

In doing so, Twitter isn't just trying to make direct messaging more compelling at a time when messaging overall is dominated by Facebook Messenger, WeChat and WhatsApp — all of which report larger user bases than Twitter. It's trying to make Twitter more appealing overall, following recent months of slow user growth, management upheaval and questions about the company's longevity.
