+1.4.0
+----------------------------------
+
+* 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
+  Functions.
+
+* 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
+  space.
+
+* The TemperatureProfile Standard Condition Function is now documented.
+
+* EulerDeform is now more flexible in specifying how the boundary
+  moves.
+
+* 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.
