A regression error has been introduced into Slic3r 1.38.xx series
for the float/percent config value, where the value was considered
unchanged if the percent sign has been added or removed.
the point type on Windows / Linux / OSX
to achieve the same behavior on all the 32 / 64bit systems.
(Windows always treats the long as 32bit int, while Linux treats
long as a 64bit int).
The problem was caused by the gap fill algorithm, which worked
with square extrusion width values as with rounded extrusion widths,
which sometimes lead to negative extrusion cross sections
for high height to width ratios.
The extrusion width logic has been changed to consider the input width
to be the extrusion spacing, not the extrusion width. The change certainly
removed the negative feed rates, but it also certainly increased the gap
fill width to some exent. It needs to be verified now, whether the gap fill
does not extrude too much.

due to the differences in the M203 code
(RepRap firmware has it in mm/min, Marlin in mm/sec).
This difference is important to the G-code time estimator.
Changed the g-code flavor to Marlin for all Prusa3D bundled profiles.

The "Send to OctoPrint" function will now send the file name encoded
in UTF-8, so the file name will not get mangled.
The C++ Slic3r::encode_path() function was returning a string to Perl,
which was marked as UTF-8. This has been fixed, now encode_path() returns
a plain Perl string.
Added path_to_filename, path_to_stem, path_to_extension, path_to_parent_path
Perl wrappers to boost::filesystem::path splitting functionality
to be able to split UTF-8 encoded files on Windows correctly.
the compatible_printers list is non empty.
Changed the precendence of compatible_printers_condition over
compatible_printers. Now compatible_printers has precedence.
There is an issue when the config wizard is started from the help
menu and the "other" workflow is followed without clearing
the user profile directory.
wizard if the wizard is opened from the menu. This allows one
to reinstall the bundled printer profile cleanly.
Fixed a bug when loading a config bundle as a config: The config bundle
should not be unpacked into the user profile directory.
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.
Fixes https://github.com/prusa3d/Slic3r/issues/456
the print/filament/printer profiles.
The change has been reverted to support the upstream slic3r
using the --datadir. While there are breaking changes
in the PlaceholderParser, if the new macro processing is not used,
the two slic3rs are still mostly interchangeable.
The "presets" subdir may be enabled with the SLIC3R_PROFILE_USE_PRESETS_SUBDIR
and it may happen, that it will be activated one day if ever the two
slci3rs diverge too much.
with the newly selected print profile,
fixed loading of print and filament tab pages after the print or filament
preset has been changed to be compatible with a newly selected printer.

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.
