Gmail (et al) finally exits beta! Well, at some point today...
As the Orly owl rightly noticed in my inbox, the tag hasn't disappeared quite yet. The change will likely occur as it has with many other Google app rollouts, taking place at exactly some time today, and may happen at various different some times depending on where you live.
The official blog post states Google has "come to appreciate that the beta tag just doesn't fit for large enterprises that aren't keen to run their business on software that sounds like it's still in the trial phase." Also, it's been FIVE YEARS. I'm pretty sure human children exit "beta" faster than that.
But hey, if you've grown kind of attached to the beta tag over the years Google has added a setting you can toggle to turn it back on. Awwe, isn't that sweet?
