+==============================
+Release Notes for OpenMC 0.6.1
+==============================
+
+-------------------
+System Requirements
+-------------------
+
+There are no special requirements for running the OpenMC code. As of this
+release, OpenMC has been tested on a variety of Linux distributions, Mac OS X,
+and Microsoft Windows 7. Memory requirements will vary depending on the size of
+the problem at hand (mostly on the number of nuclides in the problem).
+
+------------
+New Features
+------------
+
+- Coarse mesh finite difference acceleration no longer requires PETSc
+- Statepoint file numbering is now zero-padded
+- Python scripts now compatible with Python 2 or 3
+- Ability to run particle restarts in fixed source calculations
+- Capability to filter box source by fissionable materials
+- Nuclide/element names are now case insensitive in input files
+- Improved treatment of resonance scattering for heavy nuclides
+
+---------
+Bug Fixes
+---------
+
+- 03e890_: Check for energy-dependent multiplicities in ACE files
+- 4439de_: Fix distance-to-surface calculation for general plane surface
+- 5808ed_: Account for differences in URR band probabilities at different energies
+- 2e60c0_: Allow zero atom/weight percents in materials
+- 3e0870_: Don't use PWD environment variable when setting path to input files
+- dc4776_: Handle probability table resampling correctly
+- 01178b_: Fix metastables nuclides in NNDC cross_sections.xml file
+- 62ec43_: Don't read tallies.xml when OpenMC is run in plotting mode
+- 2a95ef_: Prevent segmentation fault on "current" score without mesh filter
