Missing place nodes for California counties, removing is_in tags prior to linking with boundary relations.

Adding admin_level, border_type, and boundary keys for California counties. Also 'dragged county boundary' fixup (caused a overlapping boundary error)

Adding Bird Rock to Marin County. This is still a bit broken because of 'style mismatches' between the coaslines and the admin boundaries (they should not be the same)

Removing the admin_level and administrative keys....this was being mis-identified as a county, which it isn't. The administrative keys are for government subdivisions. I suspect boundary=protected_area would be more appropriate.

Admin_centre roles for Arizona counties

Removing is_in kays for Arizona county nodes (now redundant, they are linked as label role nodes to the boundary relations)

alt_name tags for Arizona counties.

Adding admin_level, border_type and boundary keys for Arizona county and state, and national boundaries. Also simplifying (at 0.01) to reduce overnoding, keeping all conflicting nodes. Also label roles for Arizona county boundary relations.

Adding a county place node I missed. Also adding admin_centre roles for Arkansas counties (there are a few that have more than one county seat, skipped those)

Setting label roles for Arkansas county boundaries. Also fixing a couple of overlapping ways.

Simplifying all Arkansas county boundaries at 0.01 to reduce over-noding. Resolving all conflicts as 'keep'.

Setting admin_level, border_type, boundary keys on all Arkansas state 'internal' county boundary ways.

Setting admin_level, border_type, boundary keys on all Arkansas state boundary ways.

Fixing misnamed county relation. (fips code)

Fixing misnamed county relation.

Setting admin and label roles for Alabama county boundary relations. Also simplify county borders at 0.01 (less over-noding)

Creating place node for Ozark, Alabama.

Fixing alignment, changing name per 'new and misaligned TIGER roads' and user comment.

Creating boundary relations, updating metadata. Also simplifying boundary ways (at 0.01 accuracy setting) to reduce over-noding.

Deleting Wrangell-Petersburg Census Area place node. This place ceased to exist in 2013 after being reorganized into seperate jurisdictions, see WP article for details.
