-pcb-rnd 1.2.3
+pcb-rnd 1.2.4
 ~~~~~~~~~~~~~
 
-Among the usual bugfixes, the following major features have been added:
+This release starts the next major undertaking of pcb-rnd: the data
+model cleanup. The internal data model has been upgraded into a more
+proper tree; subcircuits has been added to group arbitrary objects.
 
-1. Plugin system rewrite; the original system, mostly consisting of code
-inherited from mainline, was unable to handle plugin-plugin dependencies,
-couldn't distinguish between "available" and "should load". Switched over
-the whole plugin system to puplug.
+This effort triggered various cleanups and fixes, including a more
+coherent model how layers are stored in buffers and subcircuits, enabling
+them to be reused among boards with different stackups.
 
-2. Editable mask and paste layers, using positive/negative, auto/manual
-compositing layers. Silk layers can be composite too, with manual-negative
-layers removing auto silk generated by elements. (Not yet available with
-opengl rendering.)
+The io_ plugins evolved too: pcb-rnd can read binary board files
+produced by eagle and read/write Protel's autotrax/easytrax format.
 
-3. Gtk: new layer selector widget in top window and cross-section view
-upgrades to expose the new composite layer features of the editable layers.
-
-4. eagle board import - special thanks to LA3PNA (Thomas S. Knutsen) for
-supporting the implementation
+The xy_ exporter has been upgraded to use templates for its output format.
+This enables pcb-rnd to support different fabs easier. Adding support
+for a new fab is a question of adding a new template - usually no coding
+required.
