Beautifully Integrate TNO in RV

CHANGELOG.md

@@ -9,10 +9,35 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
+* Added envelope creation from parametric vaults, middle meshes, and bound meshes, with dedicated Rhino scene layers and drawing controls.
+* Added TNO analysis for minimum and maximum thrust, minimum thickness, best fit, maximum applied load, and support displacement objectives.
+* Added objective-specific optimisation constraints and variables, with SLSQP and IPOPT solver selection.
+* Added assessment load workflows for envelope self-weight, external point loads, fill weight, and clearing all loads.
+* Added 3D thrust-network drawing, editing, and explicit form/thrust vertex and edge selection on the `FormDiagram` scene object.
+* Added envelope bounds and crack visualisation, force and reaction labels, load vectors, support displacement vectors, and configurable thrust faces, edges, vertices, and pipes.
+* Added outward, inward, downward, and manual support displacement presets.
+* Added direct template-pattern creation through `compas_tna`, including pattern-specific discretisation options.
+* Added toolbar commands and icons for envelope creation, load assignment, TNO analysis, block export, thrust inspection, and session export.
+
 ### Changed
 
+* Changed the 3D thrust network to use the existing `FormDiagram` as the single source of equilibrium geometry and force data, while retaining compatibility with existing RhinoVAULT save files.
+* Changed TNA vertical equilibrium, thrust editing, diagram export, and DEM block export to operate directly on the `FormDiagram`.
+* Changed envelope-based analysis loads to remain fixed during equilibrium updates and added an explicit RV/TNO sign-convention bridge.
+* Changed successful TNO analyses to update an existing `ForceDiagram` from the optimised form forces.
+* Changed maximum-load analysis to collect initial loads on selected thrust-network vertices and display the optimised load vectors.
+* Changed support-displacement analysis to collect and display displacement vectors on selected 3D supports.
+* Changed thrust-load drawing to display the sum of `pz` and the optimised `pzext` contribution.
+* Changed pointed-vault input validation so the rise is at least half of the larger span, and changed dome envelopes to use a fixed dense discretisation.
+* Changed the minimum `compas_tno` requirement to `0.4.0`.
+* Changed the Rhino 8 toolbar order and icons to expose the TNA, TNO, modification, and session workflows.
+
 ### Removed
 
+* Removed the separate `ThrustDiagram` data structure and `RhinoThrustObject` scene object.
+* Removed the obsolete `RV_form_solve` command.
+* Removed the local pattern-template implementations superseded by the `compas_tna` factories.
