v115.0, released 2026-07-01, "Gordian Knot"

Documentation | What's new & coming | v115.0

This version brings full Topological Layer support, including a full GUI to edit and manage data in a topological way. Topology will support SQLite, PostGIS, and Oracle databases. The code name for this release is therefore Gordian Knot.

Cadastre? Utilities? Topo's got it covered.
Meet our new Topological Layer support. Whether you're managing cadastral parcels or untangling utility networks, everything now sits on a true topological foundation — shared edges stay shared, gaps and overlaps are caught at the source, and edits propagate cleanly across connected features. Less cleanup, fewer errors, and data you can trust. One layer underneath it all: Topo.
