+Greetings,
+
+I am pleased to announce the release of PyLith 1.6.1, a finite-element
+code designed to solve dynamic elastic problems and quasi-static
+viscoelastic problems in tectonic deformation.
+
+This release fixes a few bugs in PyLith v1.6.0 and includes small
+updates to the manual and examples. We strongly recommend all users of
+previous PyLith releases switch to this latest release.
+
+  IMPORTANT NOTE:
+
+    Version 1.6.1 imposes stricter requirements on descriptive labels
+    for spatial databases and friction models. In previous versions
+    the default values (empty strings) were allowed. Users are now
+    required to specify these values as empty strings are no longer
+    allowed. This results in much better error messages.
+
+
+You can download the source code and binaries from
+
+    http://geodynamics.org/cig/software/packages/short/pylith
+
+Detailed installation instructions for the binary packages are in the
+User Manual with detailed building instructions for a few platforms
+in the INSTALL file bundled with the PyLith Installer utility.
+
+
+RELEASE NOTES
+
+* Validation of user input
+
+  Added stricter requirements for descriptive labels of various
+  objects, including spatial databases and friction models. The
+  default labels are empty strings which do not result in useful error
+  messages; the user is now required to specify a non-empty string for
+  the labels. This makes errors related to spatial databases are much
+  easier to diagnose.
+
+
+* Updates to manual
+
+  - Updated description of cell_info_fields for Neumann boundary
+    condition. The description had not been updated to reflect the
+    time-dependence introduced in version 1.4.
+
+  - Added steps 18 and 19 that discuss time-dependent Neumann boundary
+    conditions to examples/3d/hex8.
+
+
+* Bug fixes
+
+  - Fixed bug in writing rupture information to VTK and HDF5 files
+    when using multiple eartquake sources. Field names did not include
+    name of rupture. This caused loss of information in VTK output and
+    a corrupted Xdmf metadata file for HDF5 output.
+
+  - Fixed error in use of initial stress tensor with generalized Maxwell
+    models. The initial stress tensor was added to the current stress
+    tensor twice.
+
+  - Cleaned up Green's function example (examples/greensfns/hex8) so
+    that it runs without errors. Eliminated extraneous processing.
+
+  - Cleaned up meshing examples (examples/meshing), including
+    elimination of superfluous pre-processing. 
+
+  - Adjusted absolute tolerances for PETSc solves in examples/3d/hex8
+    so that solver terminates with desired convergence criterion.
+
+  - Updated examples/2d/subduction/geometry.jou to use APREPRO
+    functions and variables to store id values.
