 ---------
 
-- Improved circle raster (no longer repeats points)
+### Features
+- Implemented a 'mask' subpattern that masks out cells according to a provided
+  function
+- Added Voronoi relaxation via Lloyd's algorithm
+- Added pattern.cells: an iterator over the constituent cells in a pattern
+- Added cell_coordinates iterator, returning an (x,y) pair rather than a cell
+- Added shuffled_cells iterator, similar to cells but in a randomised order
+- Added centroid and medoid (with general distance measure) methods and tests
+- Added a Poisson-disc sampling subpattern
+- Added Mitchell's Best-Candidate sampling (approximate Poisson-Disc)
+
+### Bugfix
 - Fixed bug with subpattern.enclosed which would generate more than one enclosed
   point for a primitive.circle
+- Fixed default initialisation of RNG in automata.async_iterate
+
+### Misc
+- Improved circle raster (no longer repeats points)
 - Integrated all tests into a single test script, and added luacov coverage
-- Implemented a 'mask' subpattern that masks out cells according to a provided
-  function
 - Converted subpattern.random to take as an argument a fixed integer number of
   desired samples rather than a fraction of the domain size.
-- Added Voronoi relaxation via Lloyd's algorithm
-- Fixed default initialisation of RNG in automata.async_iterate
 - Removed special handling of '-0' coordinate in cell: No longer required with
   integer spatial hash in patterns.
 - Made pattern coordinate limits explicit in MAX_COORDINATE
 - Changed internal structure of `pattern`, from a list of cells to a list of
   coordinate hashes
-- Added pattern.cells: an iterator over the constituent cells in a pattern
-- Added cell_coordinates iterator, returning an (x,y) pair rather than a cell
-- Added shuffled_cells iterator, similar to cells but in a randomised order
-- Added example of Worley noise
 - Various optimisations
-- Added centroid and medoid (with general distance measure) methods and tests
-- Added a Poisson-disc sampling subpattern
 - Removed some (confusing) functionality from `cell`, namely addition and
   multiplication with a number value.
 - Added isoline drawing example
-- Added Mitchell's Best-Candidate sampling (approximate Poisson-Disc)
 - Renamed pretty_print to print_patterns
