at the placeholder parser.
Implemented a new PlaceholderParser::evaluate_boolean_expression()
functionality to evaluate just a boolean expression using the full
expressive power of the macro processing syntax. This function
will now be used for deciding, which print or filament preset
is compatible with which printer preset.
in a form similar to Perl:
Following expression returns true, if the variable matches the regex:
variable =~ /regex/
Following expression returns true, if the variable does not match the regex:
variable !~ /regex/
The Clipper library is not stable when calcuating offsets of contours
with holes. Replaced a single call of offset2 with offset_ex(offset_ex()).
This is not the most efficient solution, but it fixes this problem.

"Multimaterial printer switches filament at the wrong time during a print"
https://github.com/prusa3d/Slic3r/issues/607
There was a single layer between the raft top and the object first layer
missing on the wipe tower, and after this missing layer all the tool
changes were shifted by one layer, meaning two color print had the colors
switched.
bundled with Slic3r installation, and install it into user's Slic3r profile.
These bundled config bundles will be contained in the Slic3r source
tree under Slic3r/resources/profiles.
Breaking change! The Slic3r user directory has been renamed to Slic3rPE
for the Prusa Edition. Also it is likely, that the Slic3rPE directory
will be reorganized before the final 1.38 release to reserve space
for temporary profiles downloaded from the Internet.
The PlaceholderParser is currently used by the GCode.cpp
and by Printer.cpp to generate a new name for the exported G-code or SVG file.
The PlaceholderParser::process() will throw a runtime_error with
a comprehensive error message.
The G-code export will include these error messages into the G-code text
with !!!!!! separators, and the GUI will inform the user, that the G-code
export failed.
both single_extruder_multi_material and wipe_tower are enabled,
and the print prints with a single extruder only.
Newly the same situation will be handled through a conditional G-code
in the following format:
{if not has_wipe_tower}
; Do the priming
{endif}
fixed crashes when loading a config.ini with "compatible_printers"
disabled export of "compatible_printers" into gcode and config.ini
Enabled compatibility of printing multiple objects with support / no support
with a wipe tower.
gap created between the support and the support sheath.
Now the support sheath will overlap with the support base by 10%
of the extrusion width by default.
G-codes in case of single extruder multiple material setup:
At the start of the print, the filament_gcode_start is executed
for the active extruder only, and the filament_gcode_start /
filament_gcode_end are then executed at each tool change.
When the Prusa MM wipe tower is active, the tool changes are handled
a bit differently: M900 K0 is emited before the wipe tower extrusions start,
and the filament_gcode_start code is executed after the wipe tower extrusions
are done. This rule effectively disables the linear advance over the wipe tower.

Improved handling of custom G-code blocks: Slic3r will try to extract
the target extruder and bed temperatures from the custom G-code blocks.
