[3.0.4]
*Bug fixes
- Fixed OpenGL issue that prevents Cura from starting.

*License agreement on the first startup has been added

[3.0.3]
*Bug fixes
- Add missing libraries for the MakePrintable plugin.

[3.0.0]
*Faster start-up
Start-up speed has been cut in half compared to the previous version.

*New color scheme
Color scheme has been updated to reflect Ultimaker Cura rebrand.

*Updated UX design
The Ultimaker Cura logo has moved from the bottom to the top of the interface. Print status icons have been updated and repositioned.

*Redesigned splash screen
A new splash screen on Ultimaker Cura startup has been added.

*Top navigation bar improvements
The width of tab functionality changes accordingly to the word space (multilingual).

*Print quality slider
A slider can now be used to control the quality profile in recommended mode.

*Infill slider
Model infill can now be changed using a slider in recommended mode.

*Changed layer view
Layer view icon, panel and slider have moved to top-right of interface.

*Rasterized build plate
The build plate now shows graduations of 10 mm and 1 mm for easy model positioning.

*Changed row of extruder buttons
Extruder tabs have become buttons and icons have been updated.

*Add an "Export to Cura" button in SOLIDWORKS
SOLIDWORKS plugin can now be installed using an automatic installer.

*Siemens NX macro
When a user updates models in Siemens NX and clicks the button, the updated models replace the models opened in Ultimaker Cura.

*Skin removal width
Remove thin strips of skin from a model to prevent print head zigzagging, in turn preventing vibrations.

*Skin expand distance
Cutting away skins on steep overhangs makes prints less sturdy. By expanding skins with the thickness of walls, features will be better supported. In addition, features such as towers on top of infill will be stronger.

*Extra skin wall count
Printing extra skin directly on top of infill can lead to gaps, curling and pillowing. This is reduced by printing a wall around the skin first, and also improves the printing speed.

*Minimum extrusion for skin
Will prevent filling small gaps that are probably filled already, resulting in less strings, better top details and faster prints.

*PVA retractions
PVA (switch) retraction length is increased, minimum travel distance for retraction is decreased and max count is slightly increased, this reduces stringing by a lot at the cost of slightly increased print time.

*Z seam options
Gives the user control over where to place the seam - hide it in convex corners or in easy to remove locations such as concave corners. Don’t let corner angles influence the seam position.

*Quarter cubic infill
Similar to tetrahedral (octet) infill, but half of the lines are shifted half of the period up. This pattern sacrifices some rigidity of octet infill for greater toughness.

*Cross infill
A fractal pattern infill that requires fewer retractions than other infill types. This is useful for flexible materials as it causes less material elongation. The internal structure given by this infill also assists flexible models having more resistance, while retaining ‘soft’ properties in all directions.

*Layer start negative position
Layer start X/Y values can be less than 0 when the machine centre is zero.

*PostProcessing stretch script
This new script performs "post stretch" algorithm to fix the problem of insufficient inner and outer diameters. Thanks to electrocbd for contributing.

*Ironing speed settings
Ironing speed settings have been moved to experimental category.

*Doodle3D plugin
Update Doodle3D plugin to connect with printers. Thanks to mith for contributing.

*Bug fixes
- Customized profiles are not sent when connecting to a printer
- Sync z-hop with layer changes, thanks to smartavionics for contributing
- Memory leaks on MacOS
- Printer name not loaded when project file is opened
- Doodle3D Wifi box was selected by default on non-UM3 printers

[2.7.0]
*Top surface skin
Specify print settings of the top-most layers separately in order to improve print duration and achieve higher quality top surfaces.

*Print thin walls
An experimental function that enables features to be printed up to two times smaller than the nozzle size.

*Ironing (a.k.a. Neosanding)
An experimental function that enables the heated nozzle to travel over printed top layers without extrusion to create a smooth finish. Made after an idea by Neotko.

*Gradual support infill
Supports will print faster and with less material while improving overhang quality.

*Support infill layer thickness
Users are able to configure “Support infill layer thickness” for thicker support layers.

*Relative Z seam
A function that positions the Z seam relative to the bounding box of the model, so that the seam stays at the same location no matter what the position of the object is.

*Prime tower purge
In order to prevent under extrusion when printing a prime tower, and to prevent a prime tower failing half way through a job, a feature has been added to wipe off oozed/purged material in the middle of a hollow prime tower before starting to print the next layer of it. The amount of material to purge can be specified in the “Prime Tower Purge Volume” setting.

*First layer line width
A multiplier setting for the line width of the first layer of a print. Multiplying line width gives fewer lines but with greater width, which improves build plate adhesion.

*Pause standby and resume temperature
Turn off the nozzle when printing with extended pauses to prevent burned filament and nozzle clogging. At the end of a pause, the nozzle will reach printing temperature before resuming a print.

*Extruder per feature
Assign specific print features (walls, infill, skin, etc.) to a specific nozzle. A possible application of this would be to print an outer shell of an object with a fine nozzle at a greater level of detail while using a larger second nozzle to print infill faster.

*Dark theme
A dark theme for Cura. Select this theme to reduce eyestrain when working in dark environments. Activate it by selecting “Preferences > Themes > Dark".

*Top navigation bar redesign
The top bar user interface been improved so that “Prepare” and “Print” have moved from the right side of the interface to the left side.

*New keyboard shortcuts
Models can now be manipulated on the build plate using hotkeys Q, A, Z, W, and tab keys. Q selects “move”, A selects “scale”, Z selects “rotate”, and W selects “mirror”. Use the tab key to navigate between settings.

*Plugin browser
Easily download and install plugins using an integrated plugin browser. Go to “Extensions > Plugin Browser > Browse plugins” to select it.

*Import SolidWorks files as STL
A new plugin that enables SolidWorks compatible .SLDPRT files to be imported directly into Cura, where they are automatically converted to .STL format. This plugin can be found in the plugin browser.

*Zoom towards mouse cursor position
Cura preferences now include an option to zoom towards the cursor position on screen.

*Increased scroll speed in setting lists
The scroll speed in the setting lists is now three times faster than previous versions.

*Extra tooltips
Extra tooltips have been added to clarify the machine settings.

*Polish now supported
Polish language support added. This can be selected in the preferences menu.

*Chinese now supported
Chinese language support added. This can be selected in the preferences menu.

[2.6.2]

*Bug fixes
- Fixed an issue with Cura crashing on older versions of MacOS.

[2.6.1]
*New profiles
The Polypropylene material is added and supported with the Ultimaker 3. Support for CPE+ and PC with 0.8mm nozzles is added as well.

[2.6.0]
*Cura versions
Cura 2.6 has local version folders, which means the new version won’t overwrite the existing configuration and profiles from older versions, but can create a new folder instead. You can now safely check out new beta versions and, if necessary, start up an older version without the danger of losing your profiles.

*Better support adhesion
We’ve added extra support settings to allow the creation of improved support profiles with better PVA/PLA adhesion. The Support Interface settings, such as speed and density, are now split up into Support Roof and Support Floor settings.

*Multi-extrusion support for custom FDM printers
Custom third-party printers and Ultimaker modifications now have multi-extrusion support. Thanks to Aldo Hoeben for this feature.

*Model auto-arrange
We’ve improved placing multiple models or multiplying the same ones, making it easier to arrange your build plate. If there’s not enough build plate space or the model is placed beyond the build plate, you can rectify this by selecting ‘Arrange all models’ in the context menu or by pressing Command+R (MacOS) or Ctrl+R (Windows and Linux). Cura 2.6 will then find a better solution for model positioning.

*Gradual infill
You can now find the Gradual Infill button in Recommended mode. This setting makes the infill concentrated near the top of the model – so that we can save time and material for the lower parts of the model. This functionality is especially useful when printing with flexible materials.

*Support meshes
It’s now possible to load an extra model that will be used as a support structure.

*Mold
This is a bit of an experimental improvement. Users can use it to print a mold from a 3D model, which can be cast afterwards with the material that you would like your model to have.

*Towers for tiny overhangs
We’ve added a new support option allowing users to achieve more reliable results by creating towers to support even the smallest overhangs.

*Cutting meshes
Easily transform any model into a dual-extrusion print by applying a pattern for the second extruder. All areas of the original model, which also fall inside the pattern model, will be printed by the extruder selected for the pattern.

*Extruder per model selection via the context menu or extruder buttons
You can now select the necessary extruder in the right-click menu or extruder buttons. This is a quicker and more user-friendly process. The material color for each extruder will also be represented in the extruder icons.

*Custom toggle
We have made the interface a little bit cleaner and more user-friendly for switching from Recommended to Custom mode.

*Plugin installer
It used to be fairly tricky to install new plugins. We have now added a button to select and install new plugins with ease – you will find it in Preferences.

*Project-based menu
It’s a lot simpler to save and open files, and Cura will know if it’s a project, model, or gcode.

*Theme picker
If you have a custom theme, you can now apply it more easily in the preferences screen.

*Time estimates per feature
You can hover over the print time estimate in the lower right corner to see how the printing time is divided over the printing features (walls, infill, etc.). Thanks to 14bitVoid for this feature.

*Invert the direction of camera zoom
We’ve added an option to invert mouse direction for a better user experience.

*Olsson block upgrade
Ultimaker 2 users can now specify if they have the Olsson block installed on their machine. Thanks to Aldo Hoeben for this feature.

*OctoPrint plugin
Cura 2.6 allows users to send prints to OctoPrint. Thanks to Aldo Hoeben for this feature.

*Bug fixes
- Post Processing plugin
- Font rendering
- Progress bar
- Support Bottom Distance issues

*3rd party printers
- MAKEIT
- Alya
- Peopoly Moai
- Rigid3D Zero
- 3D maker

[2.5.0]
*Improved speed
We’ve made changing printers, profiles, materials, and print cores even faster. 3MF processing is also much faster now. Opening a 3MF file now takes one tenth of the time.

*Speedup engine – Multithreading
Cura can process multiple operations at the same time during slicing. Supported by Windows and Linux operating systems only.

*Preheat the build plate (with a connected printer)
Users can now set the Ultimaker 3 to preheat the build plate, which reduces the downtime, allowing to manually speed up the printing workflow.

*Better layout for 3D layer view options
An improved layer view has been implemented for computers that support OpenGL 4.1. For OpenGL 2.0 to 4.0, we will automatically switch to the old layer view.

*Disable automatic slicing
An option to disable auto-slicing has been added for the better user experience.

*Auto-scale off by default
This change speaks for itself.

*Print cost calculation
The latest version of Cura now contains code to help users calculate the cost of their prints. To do so, users need to enter a cost per spool and an amount of materials per spool. It is also possible to set the cost per material and gain better control of the expenses. Thanks to our community member Aldo Hoeben for adding this feature.

*G-code reader
The g-code reader has been reintroduced, which means users can load g-code from file and display it in layer view. Users can also print saved g-code files with Cura, share and re-use them, as well as preview the printed object via the g-code viewer. Thanks to AlephObjects for this feature.

*Discard or Keep Changes popup
We’ve changed the popup that appears when a user changes a printing profile after setting custom printing settings. It is now more informative and helpful.

*Bug fixes
- Window overflow: On some configurations (OS and screen dependant), an overflow on the General (Preferences) panel and the credits list on the About window occurred. This is now fixed.
- “Center camera when the item is selected”: This is now set to ‘off’ by default.
- Removal of file extension: When users save a file or project (without changing the file type), no file extension is added to the name. It’s only when users change to another file type that the extension is added.
- Ultimaker 3 Extended connectivity. Selecting Ultimaker 3 Extended in Cura let you connect and print with Ultimaker 3, without any warning. This now has been fixed.
- Different Y / Z colors: Y and Z colors in the tool menu are now similar to the colors on the build plate.
- No collision areas: No collision areas used to be generated for some models when "keep models apart" was activated. This is now fixed.
- Perimeter gaps: Perimeter gaps are not filled often enough; we’ve now amended this.
- File location after restart: The old version of Cura didn’t remember the last opened file location after it’s been restarted. Now it has been fixed.
- Project name: The project name changes after the project is opened. This now has been fixed.
- Slicing when error value is given (print core 2): When a support is printed with the Extruder 2 (PVA), some support settings will trigger a slice when an error value is given. We’ve now sorted this out.
- Support Towers: Support Towers can now be disabled.
- Support bottoms: When putting one object on top of another with some space in between, and selecting support with support bottom interface, no support bottom is printed. This has now been resolved.
- Summary box size: We’ve enlarged the summary box when saving the project.
- Cubic subdivision infill: In the past, the cubic subdivision infill sometimes didn’t produce the infill (WIN) – this has now been addressed.
- Spiralize outer contour and fill small gaps: When combining Fill Gaps Between Walls with Spiralize Outer Contour, the model gets a massive infill.
- Experimental post-processing plugin: Since the TweakAtZ post-processing plugin is not officially supported, we added the  ‘Experimental’ tag.

*3rd party printers (bug fixes)
- Folgertech printer definition has been added.
- Hello BEE Prusa printer definition has been added.
- Velleman Vertex K8400 printer definitions have been added for both single-extrusion and dual-extrusion versions.
- Material profiles for Cartesio printers have been updated.

[2.4.0]
*Project saving & opening
You can now save your build plate configuration - with all your active machine’s meshes and settings. When you reopen the project file, you’ll find that the build plate configuration and all settings will be exactly as you last left them when you saved the project.

*Setting search
You can now search the custom settings directly from the side panel, which means you can easily locate the setting you need to tweak. Thanks to community member Aldo Hoeben & LulzBot for this feature.

*Editing start g-code and end g-code
Aldo Hoeben also added this feature, enabling you to alter both start and end code g-code settings for single extrusion machines.

*Multiply object function
By right-clicking on an object, you can multiply it by a variable amount, rather than duplicating multiple times. Thanks again to Aldo Hoeben for this feature.

*Ultimaker 3 single extrusion prints
Dual extrusion printers now allow for single extrusion prints in a larger printable area.

*Streaming printer monitor view
Ultimaker 3’s camera views no longer only show snapshots. They now show a live stream.

*Explain why slicing is disabled
When slicing is blocked by settings with error values, a message now appears, clearly indicating which settings need to be changed.

*Ultimaker 3 print profiles
The initial and final printing temperatures reduce the amount of oozing during PLA-PLA, PLA-PVA and Nylon-PVA prints. This means printing a prime tower is now optional (except for CPE and ABS at the moment). The new Ultimaker 3 printing profiles ensure increased reliability and shorter print time.

*Initial Layer Printing Temperature
Initial and final printing temperature settings have been tuned for higher quality results. For all materials the initial print temperature is 5 degrees above the default value.

*Printing temperature of the materials
The printing temperature of the materials in the material profiles is now the same as the printing temperature for the Fine profile.

*Improved PLA-PVA layer adhesion
The PVA jerk and acceleration have been optimized to improve the layer adhesion between PVA and PLA.

*Default build plate adhesion type for Nylon
The default build plate adhesion type for Nylon prints has been changed from raft to brim.

*Support Interface Thickness
The Support Roof Thickness is now 0.8 mm and PVA support infill has been slightly decreased to lower the printing time.

*Ultimaker 2+ PC prints
In the polycarbonate profiles, the raft settings for the 0.25 mm and 0.4 mm nozzles are tweaked for less warping.

*Hollow prime tower
Print the prime tower hollow to minimize material use while maintaining stability. Wiping the oozed material on the prime tower is now done from the inside, which means the excess material is contained within the prime tower.

*Precooling and prewarming
Printing now starts at a lower temperature, before increasing swiftly to the normal printing temperature. Cooling also starts earlier than the last extrusion (with that print core). This minimizes the material’s heat absorption, which decreases the amount of degradation of the PVA material. This reduces the risk of clogging your nozzles.

*Remove Mesh Intersection
You are now able to turn off resolving of overlapping meshes. Models can now overlap, so you can perform build plate color mixing, by placing meshes over one another and lowering their flow.

*Alternate Mesh Removal
For areas where two models overlap, let each layer of the overlapping volume alternate (depending on which object the overlapping area of that layer belongs to). This improves the bonding between dual color models and allows for more controlled build plate color mixing.

*Hollow Object
Remove the infill from a mesh and treat internal cavities as overhangs, so as to create support in the model’s interior. This experimental setting greatly reduces the amount of material needed on the inside of the print.

*Fill Gaps Between Walls
Fill up small gaps between consecutive walls, making thin pieces in your model dense, rather than hollow. This feature makes the thin pieces stronger.

*Cubic subdivision infill
This experimental new infill pattern is similar to cubic infill, but generates bigger cubes farther inside the mesh. This greatly reduces print times and material use, while maintaining structural integrity. Thanks to community members Martin Boerwinckle and Nicholas Seward for this feature.

*Concentric 3D infill
This new infill pattern is similar to concentric infill, but touches the shell every X layers, creating better support for the top layers.

* Printing Temperature Initial Layer
Nozzle temperature to be used during the first layer.

*Build Plate Temperature Initial Layer
Bed temperature to be used during the first layer.

*Initial Fan Speed
Fan speed to be used during the first layer.

*Retract at Layer Change
Retract each time the printer progresses to the next layer.

*Outer Wall Wipe Distance
Wipe the nozzle after printing the outer wall.

*Set X-Y coordinate of z-seam
Select where to place the Z seam.

*Start Layers with the Same Part
Start each layer with the part closest to a given location.

*Turn off nozzle after last use
Turn off the nozzle after its last use, while other nozzles are still in use.

*Option for no build plate adhesion
Select not to print any build plate adhesion helper parts.

*Anti-overhang and support meshes
Use a mesh to specify a volume within which to classify nothing as overhang for support or specify a volume within which to print support.

*Delta printer support
This release adds support for printers with elliptic buildplates. This feature has not been extensively tested so please let us know if it works or get involved in improving it.

*AppImage for Linux
The Linux distribution is now in AppImage format, which makes Cura easier to install.

*bugfixes

Fixed an issue with automatic profile importing on Cura 2.1 on Mac OSX
Fixed an inheritance issue for dual extrusion
Fixed an issue with "i" symbol updates
Fixed a freeze that can occur while printing via Wi-Fi

[2.3.0]
*Multi Extrusion Support
Machines with multiple extruders are now supported. Ultimaker 3 printers and Ultimaker Original printers with dual extrusion upgrade kit are currently supported.

*Network Printing for Ultimaker 3
Sending a print to an Ultimaker 3 remotely via the network is now possible. Requires Wi-Fi or LAN to connect to the printer.

*Print Monitoring for Ultimaker 3
You can monitor your print on an Ultimaker 3 with a live camera feed. Requires Wi-Fi or LAN to connect to the printer.

*Improved Position Tool
Place objects precisely where you want them by manually entering the values for the position.

*Custom Machine Support
It’s now much easier to use Cura with custom machines. You can edit the machine settings when you load a new custom machine.

*Improved Grouping
It's now possible to transform objects that are already grouped.
Select an individual item in a group or merged object and edit as usual. Just Ctrl + Click and edit away.

*Enhanced Profile Management
Profile management is improved. You can now easily see and track changes made to your profiles.

*Improved Setting Visibility
Make multiple settings visible at the same time with a checkbox. The Visibility Overview setting indicates why a setting is not shown in the sidebar even if it is enabled.

*Improved time estimation
Time estimations are more accurate. Based on our test time estimations should be within 5% accuracy for Ultimaker printers.

*Optional G-code Machine Prefix
Disable the g-code prefix in Preferences. No more UM2_ on your printer display!

*Print Weight Estimates
Cura now estimates print weight as well as length.

*Automatic Import Configuration
Configurations from older installations of Cura 2.1 are automatically imported into the newest installation.

*Slicing features
*Infill Types
Two new infill types are now introduced: Tetrahedral and Cubic. They change along with the Z-axis for more uniform strength in all directions. There are now seven infill types to choose from.

*Gradual Infill
Gradual infill lets users adjust infill density, based on the distance from the top layers. This offers faster printing and reduced material requirements, whilst maintaining surface quality.

*Set Acceleration and Jerk by Feature
You can now set Jerk and Acceleration by feature-type (infill, walls, top/bottom, etc), for more precision.

*Outer Wall Offset
If your outer wall line width is smaller than your nozzle size, move the nozzle a bit inward when printing the outer wall, to improve surface quality.

*Enhanced Combing
The “No Skin” option allows you to comb over infill only to avoid scars on top surfaces.

*Z Hop
Can’t avoid previously printed parts by horizontal moves? The Z Hop Only Over Printed Parts gives you the ability to Z Hop to avoid collisions for better surface quality.

*Skin and Wall Overlap
The Skin Overlap setting allows you to overlap the skin lines with the walls for better adhesion.

*Adjust Initial Layer Travel Speed
Set the travel speed of the initial layer(s) to reduce risk of extruder pulling the print from the bed.

*Support Interface
It is now possible to print a support bottom as well as a support roof. Support bottoms are placed where the support rests on the model. Printing the support interface with PVA leads to improved surface quality.

*Bug fixes

[2.1.3]

*Material Profiles
New material profiles for CPE+, PC, Nylon and TPU for the Ultimaker 2+ family.

[2.1.2]

Cura has been completely reengineered from the ground up for an even more seamless integration between hardware, software and materials. Together with its intuitive new user interface, it’s now also ready for any future developments. For the beginner Cura makes 3D printing incredibly easy, and for more advanced users, there are over 200 customizable settings.

*Select Multiple Objects
You now have the freedom to select and manipulate multiple objects at the same time.

*Grouping
You can now group objects together to make it easier to manipulate multiple objects.

*Undo/Redo
You can now undo and redo your actions, like moving an object or scaling.

*Setting Profiles
The new GUI allows custom profiles to load easily and intuitively, directly from Cura.

*3MF File Loading Support
We’re happy to report we now support loading 3MF files. This is a new file format similar to AMF, but freely available.

*Intuitive Cut-Off Object Bottom 
We’ve added a feature that allows you to move objects below the build plate. You can either correct a model with a rough bottom, or print only a part of an object. Please note that the implementation differs greatly from the old one when it was just a setting.

*64-bit Windows Builds 
An optimized 64-bit Windows Cura version is now available. This allows you to load larger model files.

*Automatic calculations
Cura allows you to set a number of lines/layers instead of millimeters. The engine automatically calculates the right settings.

*Per-Object Settings
Per-object settings allow you to override individual profile settings per object.

*Engine Features

*Line Width
Line width settings added per feature: Global, Walls, Top/Bottom, Infill, Skirt, Support.

*Pattern Settings
Pattern settings improved per feature: Top/Bottom, Infill, Support.

*Shell

*Alternate Skin Rotation
Helps to combat the pillowing problem on top layers.

*Alternate Extra Wall
For better infill adhesion.

*Horizontal Expansion
Allows to compensate model x,y-size to get a 1:1 result.

*Travel

*Avoid Printed Parts
When moving to the next part to print, avoid collisions between the nozzle and other parts which are already printed.

*Support

*Stair Step Height
Sets the balance between sturdy and hard to remove support. By setting steps of the stair-like bottom of the support resting on the model.

*ZigZag
A new, infill type that’s easily breakable, introduced specially for support.

*Support Roofs
A new sub-feature to reduce scars the support leaves on overhangs.

*Support Towers
Specialized support for tiny overhang areas.

*Special Modes

*Surface Mode
This mode will print the surface of the mesh instead of the enclosed volume. This used to be called ‘Only follow mesh surface’. In addition to the ‘surface mode’ and ‘normal’, a ‘both’ mode has now been added. This ensures all closed volumes are printed as normal and all loose geometry as single walls.

*Experimental Features

*Conical Support
An experimental filament, cost-reduction feature, for support.

*Draft Shield
Prints a protective wall at a set distance around the object that prevents air from hitting the print, reducing warping.

*Fuzzy Skin
Prints the outer walls with a jittering motion to give your object a diffuse finish.

*Wire Printing
The object is printed with a mid-air / net-like structure, following the mesh surface. The build plate will move up and down during diagonal segments. Though not visible in layer view, you can view the result in other software, such as Repetier Host or http://chilipeppr.com/tinyg.
