# GCmaker 0.5.1 - 2026-10-21 (UTC) ### Completed - Fixed newly added miter and other end conditions missing from the design tree. - Linear Nest > Select Parts shows file names so files sharing a part number can be distinguished. - Save Strategy As can replace an existing strategy from an edited toolpath, open its folder, and immediately apply the saved version. New saves refuse duplicate names of the same type; canned replacements require Developer Mode. - Applying an angle plasma strategy preserves the operation's selected Machine Orientation. Picking, preview, animation and supported fixed-setup output follow the loaded part. - Corrected stretched lead and guide lines when previewing plasma toolpaths in a rotated Machine Orientation, including manually added edges without modifiers. ### In progress - Operator verification of the end-condition tree refresh and Select Parts file-name display. - Operator verification of strategy replacement and Save/Replace and Apply. - Operator verification of the loaded-angle preview correction; Bob confirmed orientation preservation. Non-Base rotary plasma, Auto Probe, machine-frame torch poses and native arcs rotated out of XY remain unsupported.
