+* Gale now uses linear pressure elements. This solves a number of
+ problems with stability and robustness, and makes the code much
+ faster to boot. Constant pressure elements are no longer supported,
+ and the accompanying NodalPressure variables will no longer work.
+ This will require modifying your input files. See the file UPGRADE
+ for step-by-step instructions.
+* The Mohr-Coulomb rheology has been removed. Please use
+ Drucker-Prager instead. Mohr-Coulomb and Drucker-Prager are the
+ same in 2D, and Mohr-Coulomb never really worked in 3D.
+* VTK Output now occurs after a Stokes solve, but before any advection
+ or strain integration.
+* Drucker-Prager can optionally implement a frictional boundary layer.
+* The output of the current time and timestep has been clarified.
+* The Paraview examples have been updated to version 3.4.0.
+* The documentation details how to modify Standard Condition
+* Results for the Geomod 2008 benchmarks are in the manual.
+* Divergent flow has been added, along with one example and a
+ benchmark test case.
+* The yielding fraction in the particle vtk output has been replaced
+ by the post failure strain. The yielding fraction can be derived
+ from the post failure strain, but not vice-versa.
+* There is a new field in the particle vtk output,
+ "Currently_Yielding", which is 0 or 1 depending on whether the
+ material is yielding on that time step.
+* Erf and Erfc have been added as Standard Condition Functions, and
+ AnalyticalTemperatureIC now works with Windows 32 bit.
+* A bug in how rotation is applied to shapes has been fixed.
+* The StepFunction Standard Condition Function now works in time or
+* The TemperatureProfile Standard Condition Function is now documented.
+* EulerDeform is now more flexible in specifying how the boundary
+* The DumpSwarm output method has been removed. It was a maintenance
+ burden, and all of the information is available through the VTK
+ files. This also means that it is no longer possible to visualize
+ the results with a spreadsheet like Excel.
+* The documentation has been updated to use Paraview 3.4.0.
+The current goals are:
+ * Merge Gale back with the VPAC code. This should give Gale multigrid
+ solvers, restart capability, and improved PETSc compatibility.
+ * Deformed lower boundaries
+ * Interface with custom surface process models in parallel
+ * User-specified non-uniform mesh spacing.
