 ## BambuStudio SoftFever change notes:
 
+### [V1.4.2 changes](https://github.com/SoftFever/BambuStudio-SoftFever/releases/tag/v1.4.2):
+- Change the color theme :)
+- Fixed a crash issue when selecting vase mode on some machines
+- Port firmware retraction and Extra length on restart retraction feature from PrusaSlicer
+- Fine-tune calibration features
+   1. Enforce max volumetric speed in PA line mode
+   2. Ensure print speeds are consistent across all blocks in the flow-rate calibration process. This is to help users calibrate those challenging filaments(such as TPU) by minimizing the influence of printing speed - thanks @psiberfunk for his input on this
+- New printer models: thanks @erebus04 and @GP3D84
+   1. Tronxy X5SA 400
+   2. Artillery Sidewinder
+- QoL:
+   1. Now allow exporting g-code for BBL printers
+   2. Fixed a bug that printer connection info was removed after loading a 3mf project
+fixed an issue that user presets were not loaded when Auto sync user preset option was off in Preference.
+   3.Germany language translation - thanks @hliebscher
+- Misc fixes:
+   1. Exit calibration mode when a new model is added to the scene(creating a new project after calibration is recommended)
+   2. Skip emitting M106 P2 command if the auxiliary fan is not enabled.
+   3. Fix an issue that previously there was a z-fighting issue when bed models are used for 3rd party printers
+   4. Fixed an issue that max volumetric speed was not correctly calculated if flow-rate was changed per object.
+   5. CICD for Linux build - thanks @fang64
+Known issues:
+
+The Calibration menu is missing on some Mac machines. Try restarting the App can usually fix it. See [#120](https://github.com/SoftFever/BambuStudio-SoftFever/issues/120)

    3. The "Untitled" string will no longer be added if the project name is set.
    4. The "_plate_0" string has been removed from the file name if there is only one plate.

 ### [V1.4.0 changes](https://github.com/SoftFever/BambuStudio-SoftFever/releases/tag/v1.4.0):
 - Add Layer Time/Layer time(Log) display (NOTE: need more tweaking work for BBL printers as the layer time is skewed by the preparing time)
 - Add `sandwich`(inner-outer-inner-infill) mode support for Arachne engine.

    1.  Can't send sliced files to printers
    2.  AMS filaments were added to non-Bambulab printers
    3. Wrong bed setting was applied

 ### [V1.3.4 changes](https://github.com/SoftFever/BambuStudio-SoftFever/releases/tag/v1.3.4):
 1. Add a new printer order - sandwich mode:
 This new order is similar to the outer-wall-first mode in achieving the best dimensional accuracy. This new approach however avoids printing outer walls right after a long travel, which may cause artifacts on the surface in many cases.

 4. Support single wall mode on first layer
 5. Support Chamber temperature. This setting can be use in machine start G-Gcode
 6. Support thumbview for third-party printers
