- added a new tool in Gerber Editor: Mark Area Tool. It will mark the polygons in a edited Gerber object with areas within a defined range, allowing to delete some of the not necessary copper features
- added new menu links in the Gerber Editor menu for Eraser Tool and Mark Area Tool
- added key shortcuts for Eraser Tool (CTRL+E) and Mark Area Tool (ALT+A) and updated the shortcuts list
- added the possibility for multiple tool diameters in the Edit -> Preferences -> Geometry -> Geometry General -> Tool dia separated by comma
- fixed scaling for the multiple tool diameters in Edit -> Preferences -> Geometry -> Geometry General -> Tool dia, for NCC tools more than 2 and for Solderpaste nozzles more than 2
- fixed bug in CNCJob where the CNC Tools table will show always only 2 decimals for Tool diameters regardless of the current measuring units
- made the tools diameters decimals in case of INCH FlatCAM units to be 4 instead of 3
- fixed bug in updating Grid values whenever toggling the FlatCAM units and the X, Y Grid values are linked, bugs which caused the Y value to be scaled incorrectly
- set the decimals for Grid values to be set to 6 if the units of FlatCAM is INCH and to set to 4 if FlatCAM units are METRIC
- updated translations
- updated the Russian translate from 51% complete to 69% complete using the Yandex translation engine
- fixed the the labels for shortcut keys for zoom in and zoom out both in the Menu links and in the Shortcut list
- made sure the zoom functions use the global_zoom_ratio parameter from App.self.defaults dictionary.
- added a new parameter in Edit -> Preferences -> CNCJob named Annotation Size; it controls the size of the font used for annotations
- made visibility change threaded in FlatCAMObj()
- solved issue #292 where a new geometry renamed with many underscores failed to store the name in a saved project
- the name for the saved projects are updated to the current time and not to the time of the app startup
- some PEP8 changes related to comments starting with only one '#' symbol
- added a selection limit parameter for Geometry Editor
- added entries in Edit -> Preferences for the new parameter Selection limit for both the Gerber and Geometry Editors.
- created a new function named Convert Any to Gerber and installed it in Edit -> Conversion. It's doing what the name say: it will convert an Geometry or Excellon FlatCAM object to a Gerber object.
- in PDF import tool added support for paths filled and at the same time stroked ('B' and 'B*'commands)
- added a shortcut key for PDF Import Tool (ALT+Q) and updated the Shortcut list (also with the 'T' and 'R' keys for Gerber Editor where they control the bend in Track and Region tool and the 'M' and 'D' keys for Add Arc tool in Geometry Editor)
- fixed a bug in Move command in context menu who crashed the app when triggered
- Gerber Editor: when adding a new aperture it will be store as the last selected and it will be used for any tools that are triggered until a new aperture is selected.
