2x the speed.

4x the range.

8x the capacity "to send messages"

Not using the x.x versioning anymore. Just Bluetooth 5 and the next will be 6.

Also, apprently, there's 30.000 companies in the 'Bluetooth Special Interests Group' ?

Haven't look at the spec yet, but curious if they've improved the security side of communications.

edit: Here's what I'm referring to, bluetooth 4 LE mode is vulnerable to certain attacks: https://lacklustre.net/bluetooth/Ryan_Bluetooth_Low_Energy_U...

The press release above has somewhat different numbers: "four times range, two times speed, and eight times broadcast message". For the speed it's just 2x, and the 8x is only about broadcast messages.

Does Bluetooth 5 improve the reliability, latency, or the UX? I didn't need more speed, range or capacity from Bluetooth. But I did want it to cease being synonymous in my household with lag, dropouts and pairing failures.

The range is quite important, a 4x improvement is a pretty big accomplishment.

Although, obstacle/wall penetration is probably still fairly poor.

The range is really the limiting factor in IoT uses IMO...

Why is general bluetooth connectivity so "buggy"? Why am I always struggling connecting my iPhone 6s to my bose bluetooth speaker? I would love to understand that.

Wow, this press release is horrible. Full of useless business jargon. Ctrl+F "IoT": 9 results. Why do they write these things? The only people who care about bluetooth press releases are tech-literate enough to understand at least mildly useful information about the new standard.
