Out-of-canvas viewing and editing:

• Not being able to view and edit data outside the canvas boundary used to be a deal breaker in quite a few use cases. So this is going to be a bit of a breakthrough moment for quite a few users.

This is what has changed:

• There is now a new Show All mode accessible via the View menu that reveals all pixels outside the canvas boundary.
• This mode uses alpha checkerboard for canvas padding, but you can configure GIMP to temporarily or permanently use the usual padding color instead.
• You can also enable canvas boundary cue display (dotted red line).
• Color- and patch-picking, bucket-filling, and transforming now works outside the canvas. Which means you can crop past the canvas boundary or pick a source patch from outside the canvas area to heal an area inside the canvas.

New Image mode in transform tools:

• This new feature is closely related to out-of-canvas viewing and editing and was also contributed by Ell.
• Now when you e.g. rotate a single-layer image, you can use this transform type to automatically expand the canvas to include all of rotated pixels when using the default Adjust clipping mode. The switch is right next to layer/path/selection toggle at the top of any transform tool's settings.
• It's complemented by a new Image > Transform > Arbitrary Rotation… menu entry, which activates the rotate tool in the Image mode.

Filters can now extend beyond layer boundary:

• The result of some filters can be larger than the original layer. A very common example is Drop Shadow, which adds a shadow at an offset to the layer. Such filters are no longer clipped to the layer boundary by default. Instead, the layer is automatically resized as necessary when the filter is applied.
• This behavior can be toggled through the new Clipping option in the filter dialog.

Invisible layers can now be edited:

• There is now a global toggle to enable the editing of layers with disabled visibility (the eye icon in the layers docker). There was some demand for it from users, and it was easy to do, so a new contributor, woob, added this feature.

Free Select tool update:

• The Free Select tool received further usability improvements. It now supports using Alt+drag to quickly move, cut, and copy the selection, without having to commit the selection first, similarly to the rest of the selection tools.

Foreground Select tool update:

• Thomas Manni contributed a new Grayscale preview mode to the Foreground Select tool, which allows seeing the resulting mask in black and white. The usual preview mode is now called Color and choosing the color and opacity for the mask instead of imposing only 4 colors (red, green, blue, grey).

Feather Selection update:

• The Feather Selection dialog has a new Selected areas continue outside the image toggle, working similarly to the corresponding option in the Shrink Selection and Border Selection dialogs. This option affects the border behavior of the operation: when toggled, selected areas along the image border are assumed to continue past the image bounds, and are therefore not affected by the feather.

New filters:

• Thanks to Ell, GIMP is now shipping with a simple Normal Map filter (Filters > Generic) that generates normal maps from height maps. This is early initial work, a lot more is expected to be done.
• GIMP now provides direct access to more GEGL filters
• Bayer Matrix (for ordered dithering) and Linear Sinusoid (useful for halftoning), also both created by Ell, are in the Filters > Render > Pattern menu.
• Newsprint (Filters > Distorts), by Oyvind Kolås, is a GEGL version of the old GIMP filter for halftoning, plus quite a few extras.
• Mean Curvature Blur, by Thomas Manni, can be helpful to do edge-preserving blurring.
• Also, more GEGL-based filters with on-canvas preview have replaced old GIMP counterparts: Neon (Filters > Edge-Detect), Stretch Contrast (Colors > Auto), and Oilify (Filters > Artistic).
• Moreover, Michael Natterer did a simple 8-bit per channel port of 27 older filters to use GEGL buffers (they are still GIMP filters, not GEGL operations). Another filter, Van Gogh, got higher bit depth support (up to 32bpc float).

HEIF, TIFF, and PDF support improvements:

• GIMP now supports ICC profiles in HEIF images at both loading and exporting time when built with libheif v1.4.0 and newer. The exporting dialog also features a new 'Save color profile' checkbox.
• The TIFF importer now asks how to process unspecified TIFF channels: use as non-premultiplied alpha (used to be the default), as premultiplied alpha, or just import as a generic channel. This fixes a known bug with 4-channel (RGBA) TIFF files as demonstrated here.
• Finally, the PDF exporter was fixed by Lionel to export text layers inside layer groups as text correctly.

Better loading of corrupted XCF files:

• XCF loading is now a bit more resilient to corruption: it doesn't stop any more at the first layer or channel error; instead it tries to load more layers/channels to salvage as much data as possible from a corrupted XCF file.

Improvements for the macOS version:

• Alex Samorukov introduced various improvements to the macOS build of GIMP.
• First and foremost, GIMP is now compatible with macOS Catalina and doesn't have the file permission issue that the 2.10.12 build had.
• Secondly, the DMG will now open a window with an Applications shortcut that explains how to install it. He also added some fixes for command line users.
• Finally, Alex built the new version with updated 3rd party components. Among other things, this means support for color profiles in HEIF/HEIC files.

What's New in version 2.10.12:

Improving curves editing and Curves tool:

• Generic curves interaction

The interaction with curves in general has been greatly enhanced, which is an improvement both to the Curves tool and all other places where curves need tweaking (currently paint dynamics and input device settings):

• Relative motion when dragging points
• When dragging an existing curve point, it won't 'jump' anymore to the cursor position upon pressing the button. Instead it will move relatively to its current position as the cursor moves. This allows selecting a point with a quick click without moving it, and adjusting a point position more easily.
• Additionally, when the cursor hovers above a point, or when dragging a point, the coordinate indicator now show the point's position, rather than the cursor's.
• Snap to curve when holding Ctrl
• When holding down Ctrl while adding or dragging a point, the Y-coordinate will snap to the original curve. This is particularly useful for adding points along the curve.
• Likewise, the coordinate indicator shows the snapped coordinates.
• Curves tool specific interaction
