[1.27.0] - 2026-07-29

Core modify gap-fillers: the six commands every AutoCAD user reaches for, now native to the CAD dock. The toolset grows from 33 to 39 tools.

Added

• Chamfer (CHA) — straight distance-distance corner cut between two lines. Enter both cutbacks (or tick equal distances), pick the two lines, and the tool trims both to the corner and adds the chamfer segment, all in one undo step. A live dashed hover preview shows the cut before you commit, and a cutback longer than the retained leg is rejected instead of corrupting the source line. Distances stay metre-accurate in geographic projects.
• Break (BR) — split a line at a picked point, or remove the span between two picked points. Enter or right-click after the first point breaks there with no gap. The picked feature keeps the first part; the remainder is added with the same attributes. Intermediate polyline vertices survive the split, and a break on an endpoint is refused.
• Lengthen (LEN) — change a line by delta, percent, or total length. The end you click is the end that moves, extension follows the terminal segment direction, and shortening trims cleanly through intermediate vertices.
• Align (AL) — move and rotate a feature onto source/destination point pairs, with optional scaling by the pair length ratio. Enter after the first pair moves without rotating. Curves and Z/M values survive because the whole operation is a single affine transform.
• Stretch (S) — drag a crossing window, pick a base and target point, and only the vertices inside the window move. Every editable layer crossing the window is stretched in one pass, and polygon rings stay closed.
• Explode (X) — split a multipart feature into single parts, or a line/polygon boundary into single segments. Polygon segments (including interior rings) are written to a managed planx_explode line layer, and removing the source feature is optional.
• All six commands join the command line, the command palette, the shortcut guide, the tool hints, and the in-app command reference.

Changed

• CHAMFER and CHA now start the general two-line Chamfer tool, matching AutoCAD. The urban Block Chamfer keeps its own BLOCK and BLOCKCHAMFER aliases.
• The command palette alias for Extend changed from lengthen to extend to boundary, so it no longer collides with the new Lengthen command.

Compatibility

• Managed memory layers now declare their schema in the provider URI instead of building QgsField objects, removing the last QVariant usage from the plugin. PyQt6 dropped QVariant.Type, and the Hub's Qt6 checker flags QVariant regardless, while the QgsField(QMetaType) alternative would have required QGIS 3.38 and broken the 3.28 floor.

Quality

• New tests/smoke_modify_geometry.py: 21 geometry checks for the chamfer, break, lengthen, align, stretch, and explode helpers, verified on QGIS 3.44 LTR and QGIS 4.2.
• tests/smoke_runtime.py grew from 20 to 30 checks, including layer-write verification for each new tool (edit commands, part creation, and managed output layers) and a guarantee that every registered tool key has a dock button.
• tests/smoke_compat.py now enforces that every command alias resolves to a real tool key, so a future rename cannot leave an alias silently dead.

[1.26.2] - 2026-07-15

• Revert author spelling to Yusuf Eminoglu

[1.26.1] - 2026-07-13

• Plugin Hub compatibility and security-scan maintenance release; no functional changes.

Compatibility

• Scoped every QGIS enum access for Qt6 / QGIS 4: geometry types now resolve through QgsWkbTypes.GeometryType.*, and vertex and rubber-band markers through QgsVertexMarker.IconType.* and QgsRubberBand.IconType.*. This clears all 90 Qt6 enum-compatibility warnings while staying compatible with QGIS 3.28 LTR.

Quality

• Replaced defensive try/except: pass wrappers with contextlib.suppress, resolving the Plugin Hub Bandit security-scan findings that blocked 1.26.0. The same best-effort operations remain guarded, with no change in behavior.

[1.26.0] - 2026-07-13

• Target release: PlanX CAD Toolset 1.26.0 — global English workbench and documentation

Changed

• Standardized the complete user-facing workbench on concise English terminology, including dock labels, tooltips, status messages, setup dialogs, onboarding, diagnostics, release-readiness views, menus, and About content.
• Removed bilingual labels and legacy localized search aliases so command discovery, shortcut guidance, and support screenshots present one consistent global interface.
• Rebuilt the command reference, shortcut map, smoke-test checklist, and README as English-only resources while preserving the existing CAD concepts, precision-input examples, and accessibility guidance.
• Refreshed Plugin Hub release notes and citation metadata for the 1.26 release line.
• Standardized newly generated road-platform, junction-island, and buffer layers on descriptive English layer names, field names, and attribute values.

Fixed

• Made empty Enter finish a valid in-progress sketch instead of restarting the active tool and discarding vertices; incomplete sketches now remain intact and request the missing points.
• Made Escape from the focused command line clear the input and safely cancel the active CAD operation.
• Made Rotate and Mirror operate in a local metric CRS so high-latitude geographic projects preserve physical lengths, curved geometry, and Z/M values.
• Corrected Multi-Offset previews when the map canvas and selected layer use different CRSs.

Compatibility

• Preserved internal tool keys, module names, and stored settings keys used by existing projects.
• Added compatibility mapping for legacy road-platform and junction-island layers, fields, CRSs, and attribute values so existing projects are reused in place—even after a project-CRS change—while new projects receive the English schemas.
• Retained the established AutoCAD-style command aliases, keyboard shortcuts, project formats, and QGIS 3.28 through QGIS 4 compatibility range.

Quality

• Expanded release checks to detect accidental bilingual user-facing copy while allowing author and institution proper names.
• Kept all help tables, dialog controls, and workbench feedback screen-reader accessible after the terminology consolidation.

[1.25.1] - 2026-07-13

• AutoCAD-style precision input and geographic drafting accuracy

Added

• Added AutoCAD-style precision input to the dock command line and direct canvas typing: absolute x,y, relative Cartesian @dx,dy, relative polar @distance<angle, and distance-along-cursor entry.
• Enabled precision point entry across Line, Polyline, Rectangle, Circle, Polygon and Arc, plus coordinate input for Move/Copy, signed degree input for Rotate and direct factor input for Scale.

Changed

• Interpreted relative, polar and direct-distance values consistently in metres, including geographic project CRSs; absolute coordinates remain in the map canvas CRS.
• Made Circle, Rectangle, Polygon and Arc construction metric-safe in geographic projects, including polar caps, and consolidated shared CRS transformations in core/crs_utils.py.

Quality

• Added parser, state-safety, projected/geographic/polar geometry, transform-tool, dock-routing and direct-key runtime coverage for QGIS 3.44 and QGIS 4.2.

[1.25.0] - 2026-07-13

• True junction corner solver and curve/ZM-safe transforms

Added

• Added an explicit Chamfer/Fillet junction-corner mode with live parameter controls and schematic feedback.
• Added a deterministic half-edge junction solver for X, T and skew intersections using true curb support-line intersections.

Fixed

• Made the Junction chamfer distance effective and made the previously unreachable fillet workflow available.
• Kept opposite approaches of the same through-road separate and matched connection endpoints exactly to transactionally trimmed curb endpoints.
• Prevented single-road, incomplete-arm, reflex-sector and unsafe acute-angle junction attempts from changing geometry.
• Closed median/refuge ends per directional road arm instead of drawing caps across the junction.
• Added exception-safe road rollback and compensating island cleanup when a road commit fails; island creation now refuses mixed user-owned edit sessions.
• Rebuilt teardrop islands as valid, approach-aligned bulb-and-nose polygons whose length parameter changes the actual shape and area.
• Preserved CircularString, CompoundCurve, CurvePolygon and Z/M values through Scale and Mirror affine transforms.

Quality

• Added dual-runtime pure junction, geographic X-junction integration, gap-free endpoint, refuge/island, injected-failure rollback and curved Z/M regression coverage for QGIS 3.44 and QGIS 4.2.

[1.24.0] - 2026-07-13

• Metric-safe CAD, transactional edits, and workbench reliability

Fixed

• Made cross-layer Trim, Extend and Fillet operations CRS-safe; measurement now uses the selected feature layer CRS.
• Extended short lines reliably to distant boundaries and ignored intersections behind the endpoint.
• Preserved all multipart components in Divide/Trim and prevented incompatible same-name output layers from being reused.
• Checked edit, add, change, delete and commit results throughout the toolset; plugin-owned edits now roll back on failure and user-owned edit sessions remain open.
• Made Buffer, Hatch, Offset, Multi-Offset, Fillet, Road and Junction distances metre-accurate in projected and geographic projects through a local metric work CRS.
• Restricted junction trimming and block-remnant cleanup to PlanX/selected layers instead of modifying unrelated project layers.
• Prevented cancelled setup dialogs from leaving an inert map tool active.
• Removed ghost toolbar/menu objects and stale signal connections on plugin reload.
• Grouped Fillet, Divide, Trim, Hatch and Junction road edits into rollback-capable undo commands so partial provider failures cannot leave half-written geometry.

Workbench

• Drawing tools now start a writable target layer's edit session automatically and reject incompatible target geometry types with a clear status message.
• Buffer, Hatch, Dimension, Construction and Road workflows are no longer blocked by an unrelated read-only active layer.
• The dock now follows QGIS map-tool and edit-state changes, resets command/session state completely, and exposes explicit Edit ON/Edit OFF controls.
• Command Palette and Shortcut Guide now list all 33 workbench tools, including commands without dedicated shortcuts.
• Added keyboard-accessible diagnostics tables, read-only measurement aliases, and live CRS-label updates.

Performance and quality

• Batched Array, Multi-Offset, Divide and Hatch writes into single undoable operations, with 10,000-item Array and 20,000-line Hatch safety limits.
• Added dual-runtime lifecycle, geometry-regression and urban-workbench smoke suites for QGIS 3.44 LTR/Qt5 and QGIS 4.2/Qt6.

[1.23.3] - 2026-06-18

• docs: add CITATION.cff for Zenodo DOI integration

[1.23.2] - 2026-06-17

• Fix fillet trimming closest corner endpoints and zero vector corner bug

[1.23.1] - 2026-06-17

• Fix CRS mismatch bug when project and layer CRS differ

[1.23.0] - 2026-06-09

Fixed

• Pick aperture is now enforced. _pick_feature filtered candidates only by bounding-box intersection, so a long diagonal line or large polygon could be selected even when the click was far from its actual geometry (its bbox covered the click). The 10-px aperture (PICK_TOLERANCE) is now also enforced on the real geometry distance — picks behave like AutoCAD's pickbox.
• Two-step tools can no longer operate a feature on itself. In Fillet, Trim and Extend, the second pick could return the first feature again (click near the first line → fillet/trim a line with itself, producing garbage geometry or a confusing failure). The second pick now excludes the first feature (_pick_feature(..., exclude=...)); Fillet's hover preview uses the same layer-aware exclusion instead of a fragile id-only comparison.

Changed

• New crisp PNG icon. Replaced icons/icon_main.svg with a generated 256×256 icons/icon.png (teal drafting tile, white lines joined by an orange fillet arc, AutoCAD-style grips). SVG icons render blank/muddy in some QGIS builds and have caused Plugin Hub rejections.

Quality

• tests/smoke_compat.py gains an 11th check that statically verifies the pick-aperture enforcement and the Fillet/Trim/Extend self-pick exclusion.

[1.22.0] - 2026-05-26

Fixed

• Line/Polyline now finish correctly on QGIS 4. sketcher_base.keyPressEvent referenced the unscoped Qt.Key_Z enum, which raises AttributeError under PyQt6 — and because it sat in the elif chain before the Enter branch, pressing Enter (or any non-Escape key) crashed the handler and the sketch never completed. Switched to the scoped Qt.Key.Key_Z.
• Fillet preview is now visible. The preview rubber band is recreated if it was cleared, and the candidate arc is drawn as a bold orange dashed line. Previously a thin cornflower-blue line (or a silently-swallowed None rubber band) made the preview effectively invisible even though the fillet itself worked.

Command line (more AutoCAD-like)

• Empty Enter repeats the last command (AutoCAD muscle memory).
• The input clears after each run, so you can chain commands: type L ↵, draw, type O ↵, …

Quality

• New runtime check exercises the full Line/Polyline draw pipeline (rubber-band construction → geometry build → feature insertion) on both QGIS 3 LTR and QGIS 4.
• Static Qt-enum scan now also catches unscoped Qt.Key_*, mouse-button, and modifier members (the exact bug class fixed above).

[1.21.0] - 2026-05-26

AutoCAD-style command line

• The dock search box is now an AutoCAD-style command line. Type a command alias and press Enter to launch the tool: L→Line, PL→Polyline, REC→Rectangle, O→Offset, TR→Trim, EX→Extend, F→Fillet, CO/CP→Copy, MI→Mirror, RO→Rotate, SC→Scale, AR→Array, H→Hatch, DIM→Dimension, XL→Construction line, and more.
• Autocomplete popup suggests commands as you type (case-insensitive prefix match over aliases + tool names).
• Command history: Up/Down arrows recall previously entered commands like a terminal (50-entry ring, consecutive duplicates skipped).
• Resolution precedence: AutoCAD alias → exact tool key → fuzzy name match. Unknown input echoes Unknown command: … instead of doing nothing.
• The alias→tool mapping and resolution precedence are asserted on both QGIS 3 LTR and QGIS 4 in the runtime smoke probe.

[1.20.0] - 2026-05-26

Stable release — full accessibility coverage, verified on QGIS 3 LTR and QGIS 4.

Accessibility (completed)

• The tool search box and the Road / Junction / Block Chamfer buttons now expose accessibleName / accessibleDescription. Combined with 1.19.0, every interactive control in the dock (tool buttons, quick actions, urban buttons, search, usage counter) is now screen-reader friendly with no bare-emoji announcements.

Quality

• Verified clean CAD dock construction on both QGIS 3.x LTR and QGIS 4 runtimes through the full release gate (doctor + encoding audit + dual-runtime smoke + zip verification).

[1.19.0] - 2026-05-26

Accessibility

• Screen readers: icon-only tool buttons and quick-action buttons now set accessibleName / accessibleDescription, so assistive technology announces a useful tool description instead of a bare "button". The dock itself has an accessible name.
• Keyboard navigation: tool buttons are now tab-focusable (Qt.FocusPolicy.TabFocus) with a visible focus ring on both tool buttons and quick-action buttons.

Compactness

• Status strip consolidation: the layer-state label and the session usage counter now share a single horizontal row (3:1 width split) instead of two full-width stacked rows, reclaiming vertical space in the dock.

Tests

• tests/smoke_compat.py gains a dock-accessibility check (9 checks total).

[1.18.0] - 2026-05-26

Improvements

• Compact GUI: Replaced the 15-button single-row overflow layout (broken at 160px dock width) with a semantic 3×4 QGridLayout. Buttons are grouped by function: workflow controls (Edit / Cancel / Repeat / Preflight), help & docs (Docs / Keys / Start / Health), and diagnostics (Stats / Diag / Pin / Reset WS).
• Static smoke test: Added tests/smoke_compat.py — an 8-check static compatibility smoke test runnable without a QGIS installation (py -3 tests/smoke_compat.py). Verifies Qt6 enum safety, split-geometry unpack safety, metadata correctness, icon existence, classFactory presence, and qgis.PyQt import discipline.

[1.17.7] - 2026-05-26

• Qt6 compatibility fixes (DialogCode/EditTrigger/NoWrap), Help Tool fallback behavior, and compact dock spacing refresh.

[1.17.6] - 2026-05-26

• Qt5/Qt6 compatibility hardening for dock UI, rich-text enum fixes, and QGIS 3.40+/4 runtime validation.

[1.17.5] - 2026-05-26

• Maintenance release: refreshed Plugin Hub package with QGIS 4 compatibility fixes and repaired CAD UI text encoding.

[1.17.4] - 2026-05-26

• Repair mojibake in CAD UI text and tool messages.

[1.17.3] - 2026-05-26

• Fix QGIS 4 / Qt6 enum compatibility for the CAD dock and dialogs.

[1.17.2] - 2026-05-26

• fix: Qt.ApplicationShortcut to Qt.ShortcutContext.ApplicationShortcut for PyQt6/QGIS 4

[1.17.0] - 2026-05-23

• Beta completion release: readiness, diagnostics, smoke test, issue template, UX and shortcuts

Added

• Dock favorites flow (Pin Last + Favorites row) for persistent one-click tool access.
• Dock state persistence across sessions (search text, recent tools, favorites, usage counter).
• Diagnostics report dialog (dock Diag button + Ctrl+Alt+D) with copy-ready support text.
• Workspace state reset flow (Reset WS button + Ctrl+Alt+R) for rapid clean-session recovery.

• Command palette upgraded with category filtering, additional search aliases, and usage-based ordering.
• New docs tab with QGIS smoke test checklist for release-candidate validation.
• Direct smoke-test opener (Ctrl+Alt+M) for faster RC verification in QGIS.
• Issue template dialog (Ctrl+Alt+N) that includes diagnostics text for structured bug reporting.
• Release readiness dashboard (Ctrl+Alt+V) combining health, shortcut, docs, and metadata checks.

[1.16.0] - 2026-05-23

Onboarding and operational visibility pass.

Added

• Quick Start dialog (menu, dock Start button, and Ctrl+Alt+Q shortcut).
• Live usage counter in dock to track session tool-activation volume.
• Shortcut references updated for quick-start access.

[1.15.0] - 2026-05-23

Session control and readiness pass for daily production use.

Added

• System shortcuts:
  • Ctrl+Alt+E toggle active-layer editing
  • Ctrl+Alt+F run preflight checks
• Current-layer auto refresh in plugin lifecycle (including safe disconnect on unload).

[1.14.0] - 2026-05-23

Editing workflow and preflight safety pass.

Added

• Toggle Layer Editing action (Ctrl+Alt+E) and dock Edit ON/OFF control.
• Dock Preflight button for quick checks (active layer present + vector + editable).
• Auto layer-state refresh when current layer changes.

[1.13.0] - 2026-05-23

Operational control and safety pass for production drafting sessions.

Added

• Cancel Active Tool action (dock button + Ctrl+Alt+C) for immediate safe exit from current tool.
• Layer edit-state indicator in dock showing active layer name + editable/read-only status.
• Dock status sync enhancements after cancel/activate to reduce ambiguous tool state.

[1.12.0] - 2026-05-23

Beta acceleration pass with command access and workflow reset controls.

Added

• Global Command Palette (Ctrl+Alt+P) for fast command activation by typing.
• Dock quick controls:
  • Reset button clears active tool filter
  • Clear button clears recent-tools strip
• Shortcut references updated with command palette entry in dialog and HTML docs.

[1.11.0] - 2026-05-23

English-first documentation revision + beta usability upgrades.

Added

• English-primary documentation in both command and shortcut HTML references.
• Searchable shortcut center (dialogs/shortcut_help_dialog.py) with command/category filters.
• Live workflow hint panel in the dock (Tip) that updates per active tool.
• Global docs shortcut: Ctrl+Alt+H opens Command Reference.

[1.10.0] - 2026-05-23

HTML documentation and in-dock help integration for command mastery.

Added

• New in-plugin HTML docs dialog (dialogs/docs_dialog.py) with two tabs:
  • docs/command_reference.html (detailed command usage and workflow tips)
  • docs/shortcuts.html (full keyboard map)
• Dock quick actions now include Docs and Keys buttons for one-click help access.
• New menu entry: Command Reference.

[1.9.0] - 2026-05-23

Beta completion hardening pass for CAD accessibility and operator speed.

Added

• Construction mode direct access in dock: construction_ray and construction_seg are now visible as dedicated buttons next to infinite construction lines.
• Advanced shortcut layer:
  • Ctrl+Alt+K -> Construction Ray
  • Ctrl+Alt+L -> Construction Segment
  • Ctrl+Shift+S -> Focus dock tool search
  • Ctrl+Shift+/ -> Open shortcut guide
• Shortcut guide dialog (dialogs/shortcut_help_dialog.py) for discoverability and onboarding.

[1.8.0] - 2026-05-23

Beta completion release candidate for high-speed CAD workflows.

Added

• Dock quick search: type tool names or aliases in the new Find tool box and press Enter to launch the first match.
• Recent tools strip: last 3 activated tools are pinned in the dock for one-click reactivation.
• Activation sync: tools launched from keyboard shortcuts now sync back to dock button state and recent history.

[1.7.0] - 2026-05-20

Hatch / Pattern Fill + Construction Lines.

Added

• Hatch tool (tools/tool_hatch.py): pick a closed polygon, configure pattern (parallel, cross, diagonal up/down), spacing (m), angle (°) and colour. Hatch lines are computed by sweeping the polygon's bounding box and clipping each line to the polygon, then written to the auto-created planx_hatch layer with attributes source_layer, pattern, spacing_m, angle_deg, color. Multipart-safe (multi-line intersections are split per part).
• Construction Line tool (tools/tool_construction_line.py): 2-click reference line with three dispatch modes:
  • construction_inf — extends _INF_EXTEND_FACTOR × canvas diagonal past both reference points (infinite reference).
  • construction_ray — extends only past the second point.
  • construction_seg — bounded segment. Writes to the auto-created planx_construction layer; the dashed cyan style is applied on first use.
• New icons cad_hatch.svg and cad_construction.svg registered in the dock's Edit group.
• Shortcuts: Hatch = Ctrl+Shift+H, Construction (infinite) = Ctrl+Shift+K.

[1.6.0] - 2026-05-20

• Add Join, Divide, and Multi-Offset tools, and make the interface compact

All notable changes to PlanX CAD Toolset are documented here. Format: Keep a Changelog · versioning: SemVer.

[1.5.0] - 2026-05-20

Vertex Edit + Live coordinate read-out.

Added

• Vertex Edit tool (tools/tool_vertex_edit.py):
  • Click a line or polygon feature to render every vertex as an orange handle.
  • Drag a handle to move a vertex; release to commit.
  • Click anywhere on the line itself (within ~8 px) to insert a new vertex at the click position.
  • Right-click a handle to delete that vertex; deletions are refused if they would invalidate the ring (line < 2 vertices or polygon ring < 4).
  • Multipart-safe via per-part vertex IDs.
• Live coordinate widget (dialogs/coord_widget.py) inside the dock:
  • Real-time cursor X / Y from the canvas' xyCoordinates signal.
  • Current CRS auth-id and scale denominator from mapSettings() and scaleChanged.
  • Compact monospace read-out styled to the dock palette.
• Vertex Edit keyboard shortcut: Ctrl+Shift+V.
• New icon cad_vertex_edit.svg in the Edit group.

[1.4.0] - 2026-05-20

Keyboard shortcuts framework + tool history.

Added

• 15 Ctrl+Shift+<letter> shortcuts registered as Qt.ApplicationShortcut on the QGIS main window:
  • Drawing: Line, Polyline, Rectangle, polyGon (G), Circle, Arc
  • Editing: Offset, Trim, Extend, Fillet, Buffer, arraY
  • Transform: Move
  • Measure: Dimension, I (distance measurement)
• Ctrl+Shift+Space: repeat the last activated tool (CAD convention).
• Dock: new "Repeat Last Tool" button next to the status bar.
• Tool-button tooltips now show their keyboard shortcut as a [Ctrl+Shift+X] suffix.

Changed

• main_plugin tracks self._last_tool_key updated on every activation.
• _activate_tool recognises an __repeat__ sentinel emitted by the dock's repeat button and reroutes it through _repeat_last_tool.
• Plugin owns the QShortcut instances; they are disabled and deleted on unload.

[1.3.0] - 2026-05-20

Two new tools added to the dock.

Added

• Array tool (tools/tool_array.py):
  • Rectangular mode: rows × cols with independent Δx / Δy spacing
  • Polar mode: count + sweep angle, with on-canvas center click and live preview of all rotated copies
  • Copies inherit source attributes; uses rotate_geometry (multipart-safe)
• Linear Dimension tool (tools/tool_dimension.py):
  • Click two points (snap-aware); commits a dimension line on the auto-created planx_dimensions memory layer
  • Attributes: distance_m, label (12.34 m or 1.234 km), from_x/y, to_x/y
  • Auto-enables labels showing the label field on first use
  • Right-click resets between dimensions; Esc cancels current segment
• New icons cad_array.svg, cad_dimension.svg in the dock (Edit and Measure groups respectively).

Changed

• main_plugin._create_tool now dispatches array and dimension; array joins the dialog-tool set so each invocation re-asks parameters.

[1.2.0] - 2026-05-19

UI overhaul + correctness pass.

Added

• Dock panel now scrolls (vertical QScrollArea) so all categories fit on small/narrow screens; min width 180 px.

Fixed

• Trim: splitGeometry 3-tuple unpack error on QGIS 3.x — now handles 2- and 3-return-value APIs.
• Fillet: create_fillet_and_trims always drew the counter-clockwise (long) arc; now picks the shortest arc between tangent points.
• Scale / Mirror: multipart polygons (with holes or multi-rings) were silently flattened to a single ring. New _transform_vertices helper preserves topology for point/line/polygon, single- and multi-part.
• Extend: crashed on multi-part input (asPolyline on multi); now reads the first part safely. Multi-intersection chooses the closest landing point to the line's tip.
• add_feature_to_layer: committed unconditionally, prematurely persisting the user's in-progress edits. Now commits only if it started the edit session.
• Buffer: attributes were written via "last feature in getFeatures()" which is order-fragile — attributes are now set on the QgsFeature before insert.
• QInputDialog parent set to QGIS main window for Fillet, Offset, Polygon (previously None → off-screen positioning on multi-monitor setups).

Fixed (urban)

• Block Chamfer and Junction: premature commitChanges could persist the user's open edits on their own road layers. All three sites now use the "preserve user's edit session" pattern (was_editing guard).

Removed

• sketcher_utils.trim_geometry_at_point (broken: click_point was unused, function returned the input unchanged).
• sketcher_utils.fillet_corner (broken: used smooth() not a real fillet; vertex_index was unused).
• Dead helpers in tool_fillet: _get_line_points, _find_direction_from_intersection, _trim_line_at_point — superseded by create_fillet_and_trims / trim_line_to_point.

[1.1.1] - 2026

• Standardized Plugin Hub metadata, aligned icon metadata, added DEU educational context, and refreshed the stable release package.

[1.1.0]

• Fixed intersection topology (A-B road connection).
• Renewed block chamfering logic via EasyFillet integration.
• Custom 'O' cursor added.
• Improved distance and area measurements by selection.

[1.0.0]
