+# YAPP Change Log
+
+## Rev. v3.0.1 (2024-01-15)
+* Re-organzie Git repo to maintain only the latest version in the `main` branch.
+* The core files (`YAPP_Template_v3.scad`, `YAPPgenerator_v3.scad`) now keep only a major version in their filename, and live in the root of the repo.
+
+## Rev. 3.0.0  (2023-12-01)
+
+Lead Developer for v3.0: <a href="https://github.com/rosenhauer">Dave Rosenhauer</a>
+Dave added new functionality, fixed many bugs, is the creator of the v3.0 API and did a lot of code cleanup.
+He made more than 20 merge requests in three weeks.
+
+**New functionality**
+<pre>
+Cutout Shapes
+	Cutouts now support more shapes.
+		yappRectangle	    : Rectangle with size 'width' x 'length' 
+		yappCircle	    : Circle with radius of 'radius'
+		yappRoundedRect	    : Rectangle with size 'width' x 'length' and corner 
+                                      radius of 'radius'
+		yappPolygon	    : User defined polygon. Three standard shapes are 
+                                      included for use/reference - 'shapeIsoTriangle', 
+                                      'shapeHexagon', 'shape6ptStar' 
+		yappCircleWithFlats : Circle with radius of 'radius' with the sides 
+                                      clipped to width (length is not used)
+    		yappCircleWithKey   : Circle with radius of 'radius' with a rectangular 
+                                      key of width x length (length is key depth)
+
+Cutout Masks
+
+Fillets
+	Fillets are automatically added to all appropriate items.  
+	This can be overridden with the yappNoFillet option.  
+	Fillet radius can also be changed from default (same as connected wall thickness) 
+	with the filletRadius parameter.
+
+Ridge Extension
+  Extension from the lid into the case for adding split opening at various heights
+
+//========= HOOK dummy functions ============================
+  
+// Hook functions allow you to add 3d objects to the case.
+// Lid/Base = Shell part to attach the object to.
+// Inside/Outside = Join the object from the midpoint of the shell to the inside/outside.
+
+//===========================================================
+// origin = box(0,0,0)
+module hookLidInside()
+{
+} // hookLidInside()
+  
+//===========================================================
+// origin = box(0,0,shellHeight)
+module hookLidOutside()
+{
+} // hookLidOutside()
+
+//===========================================================
+// origin = box(0,0,0)
+module hookBaseInside()
+{
+} // hookBaseInside()
+
+//===========================================================
+// origin = box(0,0,0)
+module hookBaseOutside()
+{
+} // hookBaseOutside()
+
+//===========================================================
+//===========================================================
+</pre>
+
+**Updated definition standards:**
+<pre>
+     Parameters:
+	p(0,1 ...) = a 'p' with a number between parentheses indicates a 
+	                    'positional' parameter.
+	n(a,b ...) = a 'n' with a letter between parentheses indicates an 
+	                    optional, 'non-positional' parameter must be after 
+	                    the required parameters.
+	{ yappParameter }
+	&lt;Default value&gt;
+	| means one or more values from the list are allowed
+	, means only one value from the list is allowed
+</pre>

+**This version breaks with the API for the following objects:**

+## Rev. 1.5
+
+- Various bug-fixes
+- Connectors now have a flange at the basePlane and lidPlane for a better adhesion
+
+*This release breaks with previous releases in the extra parm "**depth**" in the labels array!!*
+
+The labels now have this syntax:
+<pre>
+//-- origin of labels is box [0,0,0]
+// (0) = posx
+// (1) = posy/z
+// (2) = orientation
+// (3) = depth
+// (4) = plane {lid | base | left | right | front | back }
+// (5) = font
+// (6) = size
+// (7) = "label text"
+</pre>
+
+Example:
+<pre>
+labelsPlane = [
+                [10,  10,   0, 0.6, "lid",   "Liberation Mono:style=bold", 15, "YAPP" ]
+               ,[100, 90, 180, 0.8, "base",  "Liberation Mono:style=bold", 11, "Base" ]
+               ,[8,    8,   0, 1.0, "left",  "Liberation Mono:style=bold",  7, "Left" ]
+               ,[10,   5,   0, 1.2, "right", "Liberation Mono:style=bold",  7, "Right" ]
+               ,[40,  23,   0, 1.5, "front", "Liberation Mono:style=bold",  7, "Front" ]
+               ,[5,    5,   0, 2.0, "back",  "Liberation Mono:style=bold",  8, "Back" ]
+              ];
+</pre>
+
+For your box to work with this release as before you have to add this extra 
+parm (as "wallThickness/2", "basePlaneThickness/2" or "lidPlaneThickness/2").
+
+Thanks to *Keith Hadley*
+
+There now is a new array for connectors that holds the PCB. This array is called "**connectorsPCB**".
+<pre>
+//-- connectorsPCB -- origin = pcb[0,0,0]
+// (0) = posx
+// (1) = posy
+// (2) = screwDiameter
+// (3) = insertDiameter
+// (4) = outsideDiameter
+// (5) = { yappAllCorners }
+</pre>
+
+Example:
+<pre>
+connectorsPCB = [
+                  [pcbLength/2, 10, 2.5, 3.8, 5]
+                 ,[pcbLength/2, pcbWidth-10, 2.5, 3.8, 5]
+                ];
+</pre>
+It takes in account the "**pcbThickness**" to calculate the hight of the lid-connector.
+
+Thanks to *Oliver Grafe*

+
+## Rev. 1.4
+
+*This release breaks with previous releases in the extra parm "**angle**" in all the cutouts array's!!!*
+
+All plane array's now have this syntax:
+
+<pre>
+//-- plane    -- origin is pcb[0,0,0]
+// (0) = posx
+// (1) = posy
+// (2) = width
+// (3) = length
+// (4) = angle
+// (5) = { yappRectangle | yappCircle }
+// (6) = { yappCenter }
+</pre>
+
+For your box to work with this release you have to add this extra parm (as "***0***") to all your cutOut-array-row's

+This OpenSCAD project can be used to create extremely comprehensive and customizable project boxes/enclosures using OpenSCAD.
+
+The [complete and official documentation gitbook](https://mrwheel-docs.gitbook.io/yappgenerator_en/) explains the entire API.
+
+You can open Issues here, but please also place them in a comment at one of the following blog posts:

+
+I have done my best, but it can probably be done simpler. 
+If you think you can help, please contact me or make a Pull Request.
+
+## How to program your Project Box
+It all starts with the dimensions of the PCB going inside your Project Box, as well as a few other dimensions:
+
+```openscad
+printBaseShell      = true;
+printLidShell       = true;
+
+// Edit these parameters for your own board dimensions
+wallThickness       = 1.0;
+basePlaneThickness  = 1.0;
+lidPlaneThickness   = 1.0;
+
+// Total height of box = basePlaneThickness + lidPlaneThickness 
+//                     + baseWallHeight + lidWallHeight
+
+baseWallHeight      = 7;
+lidWallHeight       = 4;
+
+pcbLength           = 88;
+pcbWidth            = 49;
+pcbThickness        = 1.5;
+                            
+// padding between pcb and inside wall
+paddingFront        = 4;
+paddingBack         = 1;
+paddingRight        = 1;
+paddingLeft         = 1;
+
+// ridge where Base- and Lid- off the box can overlap
+// Make sure this isn't less than lidWallHeight
+ridgeHeight         = 3;
+ridgeSlack          = 0.2;
+roundRadius         = 2.0;  // don't make this to big..
+
+//-- How much the PCB needs to be raised from the base
+//-- to leave room for solderings and whatnot
+standoffHeight      = 5.0;
+pinDiameter         = 1.0;
+pinHoleSlack        = 0.5;
+standoffDiameter    = 4;
+```
+
+You probably want some cutouts in your box for connectors and stuff.
+For every plane (side) of the Project Box, there is an array that holds the cutouts for that plane.
+
+A picture is worth a thousand words ...
+
+### Cutouts in the *Right* Plane:

+
+#### With `yappCenter`, the rectangle will rotate around its center point:

+## Versioning
+* All major releases (v1, v2, v3) are intended to be compatible with all files previously designed for v3 (e.g., the v3.1 release will not remove features or make any breaking changes, compared to v3.0).
+* The filename of the library (e.g., `YAPPgenerator_v3.scad`) will thus have only the major version in its filename.
+* When a new major version is released, a branch will be created from the `main` branch at the last commit before work is started on the next major version. This branch can be used to fix bugs and add features to the old release version, if desired. These lineage branches will not be merged to `main`, and will continue on their own path.
+* All future tagged versions will have GitHub Releases created for them, which will include the changelog for the release. The `YAPP_Template_vx.scad` and `YAPPgenerator_vx.scad` files will also be attached to the release.
+* The ISO8601 international standard date format (yyyy-mm-dd) will be used for documenting dates.
