f65e770242 [FEATURE[processing] New algorithm to compute geometry by expression 
This algorithm updates existing geometries (or creates new
geometries) for input features by use of a QGIS expression. This
allows complex geometry modifications which can utilise all the
flexibility of the QGIS expression engine to manipulate and create
geometries for output features.

82312e10e4 [FEATURE][processing] New algorithm to extract specific nodes 
This algorithm allows you to extract specific nodes from geometries.
Eg you can extract the first or last node in the geometry.

The algorithm accepts a comma separated list of node indices to
extract, eg 0 = first node, 1 = second node, etc. Negative indices
can be used to extract nodes from the end of the geometry. Eg
-1 = last node, -2 = second last node.

56b77db88c [FEATURE][processing] Add choice of simplification method to simplify 
This change allows users to choose which method to use when running
the simplify geometries algorithm, with choices of the existing
distance based (Douglas Peucker) algorithm, area based (Visvalingam)
algorithm and snap-to-grid.

Visvaligam in particular usually results in more cartographically
pleasing simplification over the standard distance based methods.
