There’s loads of missing roundabouts. Locally, A34 just north of Stafford, A34/A513 in Stafford, 1 of the 3 on B5012 in Penkridge, B5013 in Uttoxeter by the A518 junction.

Within a minute I spotted two new missing roundabouts on primary routes which have been there for at least a couple of years. One is on the A449 on the northern edge of Penkridge and the other is on the A51 at Rugeley where the power station was.
As a general rule, roundabouts in urban areas are often missed out as part of the generalisation process, especially when they're with unclassified or Class III roads; and always when they're with roads that aren't important enough to appear - unless the shown road is a dual carriageway. They also don't show mini-roundabouts, so the A34/A513 ones mentioned wouldn't be expected to appear. They're simply just not important enough at this scale - but as it's generalised data, there are always exceptions that slip through.

If you want more detail, you have to up the scale - but OS don't release Landrangers as OpenData.

I think the A34/A513 roundabout he mentioned was on the north side of Stafford at Mustang Drive. This is on a dual carriageway.
How would you like your grade separations, Sir?

The 2024 annual release of 1:250k OS mapping happened just a few days ago, so it's now added to SABRE Maps.

There's a few changes from 2023 on there, with my favourite non-roads item being that Wolverhampton High Level railway station is now marked as a tram stop due to the new tram stop outside the front door having its symbol placed directly on top of the railway station symbol.

The only change around here I can see is the only legal route HGV's can take through Lichfield is now shown as primary green whereas in 2023 it is non-primary red.
