Changes

2.3.0 (latest release)

Highlights

• Explicit Python 3.11 support #1247 #1280

Experimental Features

• Constraint-based sketches are still being worked on and improved, and are not production ready. There have been fixes, but multiple issues are still open including #959, #968 and #960.
• The Convex Hull feature should also be considered experimental. Issues open for that feature include #931, #1190, #1224 and #943.

Other changes

• Various documentation fixes and updates #1250 #1251 #1256 #1262 #1305 #1306 #1309 #1240
• Added a close option to Wire.makePolygon() #1257
• Fixed iteration over entities and avoid hash collisions to help solve intermittent test failures #1260
• Added fused export for assemblies that preserves face colors #1261
• Added multilayer support to DXF export #1267
• Removed one unneeded layer of hierarchy from STEP export #1270
• Fixed a bug where Workplane.close() would not work with a set of 3D points #1271
• Fixed a missing distance parameter in an extrude example #1275
• Started building noarch packages in Azure Pipelines #1293
• Added a better version string to identify conda master builds #1315
• Fixed metadata being lost when adding a subassembly to an assembly #1327
• Added tolerance (tol) to enable fuzzy cut() and intersect() operations #1332
• Fixed relative/absolute bug in line_point sketch solver method #1336

2.2.0

Highlights

• Introduced a new Sketch API dedicated to 2D planar operations.
• New constraint types were added to use with the Assembly solver.

Breaking changes

• Renamed the argument for Workplane.extrude from distance to until and Workplane.cutBlind's distanceToCut also to until. This is only a breaking change if you use the named parameters, i.e. extrude(distance = 10.0) or cutBlind(distanceToCut) instead of using them as positional parameters.
• Fixed a bug in Mixin1DProtocol.tangentAt() where paramAt() was being called twice. This should only break scripts that relied on the incorrect behavior. #641
• each and eachpoint accept now combine argument defaulted to True #954. This only affects use cases involving solids.

Experimental Features

• Constraint-based sketches are still being worked on and improved, and are not production ready. There are multiple issues open including #1127, #959, #968 and #960.
• The Convex Hull feature should also be considered experimental. Issues open for that feature include #931, #1190, #1224 and #943.

Other changes
