 ### Added
-* Added new multi-face brep support via the `Plate.from_brep()` class method, which automatically creates plates from multi-face breps by detecting parallel faces.
-* Added `Plate.from_face_thickness()` class method for creating plates from single-face breps (replacing the previous single-face `Plate.from_brep()` behavior).
-* Added `Panel.from_brep()` class method to create panels from multi-face breps, parallel to `Plate.from_brep()`.
-* Added `Panel.from_face_thickness()` class method to create panels from single-face breps with an explicit thickness, parallel to `Plate.from_face_thickness()`.
-* Added `get_plate_geometry_outlines_from_brep` to `compas_timber.utils` — a shared utility used by both `Plate.from_brep()` and `Panel.from_brep()` to extract the two main outlines and openings from a multi-face brep using mesh-based face identification.
+
+* Added `PlateNester` main implementation with improved skyline-based placement flow, deterministic ordering support, and seeded variant generation.
 * Added new `compas_timber.btlx` package with `BTLxReader` class for reading BTLx XML files into a `TimberModel`.
 * Added `BTLxParsingError` to `compas_timber.errors` — a non-fatal exception with `part_id` and `processing_type` fields, collected during BTLx parsing without aborting the process.
 * Added `BTLxProcessing.HEADER_ATTRIBUTE_MAP` class attribute mapping BTLx XML header attributes (e.g. `ReferencePlaneID`, `ProcessID`, `CounterSink`) to Python parameter names with type converters, used by the reader.

 ### Changed
 
-* Changed minimum required `compas` version to `2.15.1` due to bugfix.
+* Improved `PlateStock`/`NestingResult` reporting integration for plate nesting, including robust unplaced-element handling and per-stock utilization/report payload consistency.
 * Fixed `Plate.geometry` is `None`.
 * Fixed `FreeContour` BTLx file creation failing with assertion `processident != 0`; `process_id` now defaults to `1` instead of the base class default of `0`.
 * Fixed circular import between `compas_timber.connections.analyzers` and `compas_timber.model` by moving `analyzers` module to `compas_timber.analyzers`.

 ### Changed
+* Changed minimum required `compas` version to `2.15.1` due to bugfix.
 * Breaking change: the previous single-face `Plate.from_brep()` constructor behavior has been replaced, and `Plate.from_brep()` is now used exclusively to construct plates from multi-face breps. Existing code that called `Plate.from_brep()` with a single-face brep should be updated to call `Plate.from_face_thickness()` for plates, or `Panel.from_face_thickness()` for panels, instead.
 * `Plate.from_brep()` now delegates all brep parsing logic to `get_plate_geometry_outlines_from_brep`, which uses `mesh_from_brep_simple` to convert the brep into a `Mesh` datastructure. Face identification and vertex correspondence are resolved through mesh topology instead of directly iterating the brep API.
 * Rewrote `polyline_from_brep_loop` to use `join_polyline_segments` internally; curved edges are no longer sampled (curved breps must be pre-tessellated before use).
