-- Modification of the "taper" behavior to match with the old SourceForge
+* Modification of the "taper" behavior to match with the old SourceForge
   version. The step coverage was not consistent: without horizontal extension
   (i.e. "grow(z, :taper => t)"), steps have been convered with a horizontal
   overlap creating a sidewall. Now, this case creates a "roof" without sidewalls 
   again.
 
-- Multiple rulers can be present now and will be turned into multiple 
+* Multiple rulers can be present now and will be turned into multiple 
   cross section views. A new dedicated ruler template "XSection" is defined and
   can be picked from the "Ruler"-dropdown menu. If such a ruler is 
   present, this one will be taken and other rulers are ignored (good
   for measuring while doing XSection runs).
 
-- Some maintenance of the geometry production algorithm with the result
+* Some maintenance of the geometry production algorithm with the result
   of less slivers and artefacts.
 
-- Up to 10 entries in the list of recent files
+* Up to 10 entries in the list of recent files
 
-- "output" will overwrite existing layers, so this function can be used
+* "output" will overwrite existing layers, so this function can be used
   multiple times (good with "snapshot" and "pause")
 
-- New function "snapshot" or "snapshot(name)": this function will rename
+* New function "snapshot" or "snapshot(name)": this function will rename
   the tab if a name is present and continue in a new tab. Note: the snapshot
   will only show the outputs collected so far. New outputs will only appear
   in the new tab. The outputs will also be shown only in the current state,
   so if you use "etch/into" for example to modify a material, you'll need
   to output it again in order to show it in the new shape on the new tabs.
 
-- New function "pause" or "pause(name)": this function will show all outputs
+* New function "pause" or "pause(name)": this function will show all outputs
   collected so far and pause with a question whether to continue or not.
   If a name is given, the output tab will be renamed to this name.
 
+* New function "dbu(d)" to change the computation accuracy. Good for achieving
+  a finer resolution for the output geometry.
