New in Version 5.2
ATTRIBUTE command
* The "Technologies" combo box in the "New/Change Attribute" dialog now lists the name of the current technology.
* Changed the behavior of the ATTRIBUTE command in case no coordinates are given in the command line, so that the value of an existing attribute can be changed via the command line.
DRC command
* The DRC now reports supply layers, that are not contained in the layer setup of the Design Rules, as "Layer Setup" errors.
SET command
* The SET command can now be used to set parameters of the eaglerc file.
Miscellaneous
* If you don't like the way unprocessed polygons display their edges (as dotted lines), you can change this with the command SET Option.DrawUnprocessedPolygonEdgesContinuous 1 The edges of unprocessed polygons will then be displayed as continuous lines, as was the case before version 5 (however, they will not be highlighted).
* The commands CUT, DRC, ERC, ERRORS, EXPORT, GROUP, OPTIMIZE, PASTE, PRINT, RATSNEST, UPDATE, USE and WRITE are now "transparent", which means they no longer terminate a previously active command like MOVE etc.
* The layers are now drawn in a sequence that properly reflects the actual resulting board. For instance, the bottom placeplan is drawn first, then the signal layers from bottom to top, then the top placeplan. This sequence is reversed when printing mirrored.
* Added a note to the online help of the PAD and VIA commands, saying that the shape only applies to the outer layers (in inner layers the shape is always "round").
* Parts on the board are now shifted into the allowed area of the Light or Standard edition, respectively, if they extend outside that area after a REPLACE, CHANGE PACKAGE or UPDATE operation.
Bugfixes
* Fixed unexpected wire fragments in CAM Processor and PRINT output.
WARNING: All EAGLE versions from 4.90.1 to 5.1.1 contain a bug which, under rare circumstances, may cause unexpected wire fragments in the CAM Processor and PRINT output, which may lead to short circuits. These wires are not visible in the editor window and are not reported by the DRC. This bug is fixed in version 5.2.0 (and since version 5.1.2, respectively). Please switch to version 5.2.0 as soon as possible. Windows users should also make sure they use the latest version of the command line version eaglecon.exe, which is automatically generated from the eagle.exe during installation. You can determine the actual version of your eaglecon.exe by calling
