+## Changes to *DIPlib*
+
+### New functionality
+
+- Added `dip::SplitChannels()` to `diplib/geometry.h`.
+
+### Changed functionality
+
+- `dip::HoughTransformCircleCenters()` now draws lines in the parameter space with an intensity proportional to the
+  magnitude of the input gradient. Low gradients are likely less precise in orientation, so down-weighing them
+  improves precision.
+
+### Bug fixes
+
+- `dip::saturated_mul()` for `dip::sint64` inputs was broken on systems that don't have 128-bit arithmetic.
+
+- Improved `dip::PhysicalQuantity::Normalize()` to avoid floating-point rounding errors.
+
+- `dip::DrawEllipsoid()` and `dip::DrawDiamond()` could produce wonky shapes for even diameters,
+  due to a floating-point rounding error.
+
+- JPEG encoding and decoding had a small memory leak.
+
+- `dip::GetOptimalDFTSize()` could loop indefinitely for inputs close to the maximum `dip::uint` value, because
+  of an integer overflow in arithmetic.
+
+- The classes `dip::StatisticsAccumulator` and `dip::VarianceAccumulator` divided by 0 when adding two empty
+  accumulators together, producing NaN values as output. This caused the function `dip::SampleStatistics()`
+  to sometimes produce NaN statistics when called with a mask image.
+
+### Build changes
+
+- Fixed some assorted issues introduced in 3.5.0 for 32-bit builds.
+  
+- Added a 32-bit build to the CI on GitHub.
+
+
+
+
+## Changes to *DIPimage*
+
+### Bug fixes
+
+None, but see bugfixes to *DIPlib*.
+
+
+
+
+## Changes to *PyDIP*
+
+### Bug fixes
+
+- `dip.ChainCode.Length()` had a parameter `boundaryPixels` added in *DIPlib* 3.3.0, but the Python bindings
+  did not know about its default value.
+
+(See also bugfixes to *DIPlib*.)
+
+
+
+
+## Changes to *DIPviewer*
+
+### Changed functionality
+
+- The `dip.viewer.SliceViewer` object now also maps the `complex` and `projection` properties
+  (matching the third and fourth columns of the "control panel").
+
+
+
+
+## Changes to *DIPjavaio*
+
+None
