Dia has pushed out another macOS update, but version 1.40.1 is unlikely to excite anyone who has been waiting for a major new feature.
Instead of any headline features, the update notes claim that it addresses performance issues. Dia has re-enabled Chromium’s back and forward cache, so pages should load faster when users move back through recently visited sites.
Then, the browser can also put more unused tabs to sleep (think of MS Edge), especially for people who keep a boatload of tabs open. They are also the sort of improvements that tend to work quietly in the background. There is no big new tool or feature here that changes how Dia works.
And this is precisely what is bothering users on Reddit. The update post in r/diabrowser quickly turned into another discussion about Spaces, the long-awaited feature that many users expected to see by now.
One commenter simply wrote, “no spaces…” Another said Dia had “become stagnant,” while a different user questioned why the company only talks about what is shipping instead of explaining what has been delayed or changed.
The frustration is not new. We reported last month that Spaces had been pushed to early July, following confirmation from a moderator in the Dia subreddit. The feature still has not arrived. Users are also waiting for other requested additions, including Little Arc-style windows.
That said, Dia has released something more substantial in between. The Reports feature arrived in an earlier update, giving users a way to turn information into formatted documents. But that release also brought the same question back into focus. When is Dia going to work on the features people have been asking for?
The presentation of version 1.40.1 does not help much. The Reddit post clearly lists the two performance changes, but Dia’s own release notes page does not appear to showcase them. Instead, it highlights app connectors and walks through a Granola and Notion example.
That is not a new addition to Dia. Users could already connect services through the Apps section and use them with New Chat. The page reads more like a reminder about existing connectors than a proper showcase for the new update.
It leaves the impression that Dia did not have much new to celebrate this week. Better memory use and faster navigation are welcome, but they are unlikely to quiet users who are still waiting for Spaces
