Quick setup via drag and drop
Choose a material, an alpha, a texture or a procedural from the Assets library, drag and drop onto the desired part of the mesh (shortcut ALT required for Materials). If your asset is not a material, a popup with inquire which channel you would like to assign it to.
Once the layer is created, you will see that the new Warp projection is automatically selected. The layer has standard 3D projection mode controls, but also a new parameter Projection Depth which allows to set the depth of the warp projection (represented by green arrows as a visual queue).
You can also select this projection mode manually on any fill layer or effect without having to drag and drop an asset into the viewport.

Automatic placement with the Surface tool
When the new Warp layer is created, you will see that the Surface tool is automatically selected. This allows you to move the image so it remains on the surface of your mesh at all times. However you can always switch to any of the other manipulators and adjust its translation (shortcut W), rotation (shortcut E) or scale (shortcut R). To return to the Surface tool, use shortcut SHIFT + W. When switching to Edit vertices mode, the Surface tool is also the default selection and it snaps vertex movement to the surface of your mesh. However you can temporarily and quickly override the surface tool by maintaining CTRL which allows you to move the selected point in any direction, not just on the surface.

Easily editable warp grid
Once the global placement of the image is done, it is also possible to edit the warp grid itself for greater precision and flexibility. To go into grid edit mode, you can either use the newly added warp menu, or the shortcut SHIFT + V. This will allow to edit existing vertices of the grid.
You can evenly subdivide the grid as a whole, but keep in mind that if you had previously moved the vertices, they will be reset to their original positions. Grid subdivision can be done via the new warp options menu.
Alternatively, it is possible to add individually placed splits which would allow to have greater detail only where needed. To add splits, select any of the three options in the warp menu - crosswise, horizontally or vertically. When one of them is selected, hovering the cursor over the Warp projection and clicking anywhere within it will add a new split. This will not alter the position of existing points.

Automatic adjustment of vertex orientation
By default tangents of individual vertices are adjusted to the mesh's surface, which means they will always be correctly oriented in relation to the mesh no matter where they are dragged. This auto-tangent option can be turned off via a new button in the contextual toolbar, in which case the orientation will remain fixed at all times.

Adjust the angle of projection
Once your image is in place, there is a new Angle setting available. This setting can be used to adjust whether the image is projected all the way around the cylindrical shape, or is restricted to a certain angle. It does not crop the image, but rather reduces its width.

New window layout
The improved color picker window has been reworked to accommodate a more vertical layout, similar to Sampler's latest release. It is divided into three sections - the main color field which includes the current and last selection, the hex field, eyedropper and the hue slider; the manual RGB/HSV sliders section; and the swatches.

New 0-255 RGB values
Alongside porting the existing ways of entering color value, the improved color picker also allows to work in 0-255 RGB values. This option is available when Floating point values is unchecked in the sliders section dropdown menu.

Saving color swatches
Color swatches can now be saved in Painter! Once the desired color is selected, it is possible to press the plus button in the Swatches section of the color picker, and the color will be stored across sessions and projects. A swatch can be cleared by right-clicking on it, or alternatively it is possible to bulk-delete all swatches at once via this section's dropdown menu. There is no limit to the number of swatches that can be saved.

Color picker window remains open
The color picker window can be now be moved around and placed anywhere, even on a different screen, and it will remain open as long as there is no context switch, which means that when you are switching between paint layers while hand painting textures, you can keep the color picker window open for easier access.

More accessible eyedropper
Now the color picking eyedropper can be found directly next to the color field, but you can still find it within the color picker as well. The more accessible eyedropper retain all previous functionalities - you can still click and hold to pick a color anywhere on your screen(s). This exposed eyedropper can be found next to all color fields in Painter, not just layer channels.

Asset drag and drop improvements
With the introduction of the Warp, the decal feature where assets can be drag and dropped from the library into the viewport while maintaining ALT had seen some rework. Now, when a decal is created this way, it is no longer using the Planar projection, but the Warp projection. Automatic selection of the Warp projection should improve speed and efficiency of decal adjustments on the mesh.
Moreover, it is now possible to drag and drop not only materials, but image-type assets into the viewport. When selecting an alpha, a texture or a procedural, there is no need to use the ALT modifier. It can be dropped onto the mesh - that would prompt a menu giving the option to select whether this image should be used within a mask or any of the layer's channels.
