 ## News
+12/05/2018:  version 1.0.3.4 released (just to fix a problem with the source 
+tarball on pypi).
+
+12/05/2018:  version 1.0.3.1 released.  Bugfix release (fixed issue with installation
+when cython not installed, regression on 32-bit platforms, workaround for pandas 
+compatibility).
+
 12/01/2018:  version 1.0.3 released. Test coverage with coveralls.io, improved round-tripping accuracy for non-real world calendars (like `360_day`).
 
 10/27/2018:  version 1.0.2 released. Improved accuracy (from approximately 1000 microseconds to 10 microseconds on x86

README.release

+* create a release branch ('vX.Y.Zrel').  In the release branch...
+* make sure version number in cftime/_cftime.pyx is correct.
+* update README.md as needed. 
+* commit and push all of the above changes.
+* create a pull request for the release branch.
+* After release branch has been merged, tag a release
+   % git tag -a vX.Y.Zrel -m "version X.Y.Z release"
+   % git push origin --tags
+  Then create a release on github from that tag.
+* Update the BUILD_COMMIT variable in .travis.yml and appveyor.yml
+  in https://github.com/MacPython/cftime-wheels.
+  Push those changes to trigger the binary wheel builds (for
+  macos x, linux and windows). 
+* Download the binary wheels from wheels.scipy.org, put them in a
+  directory called 'upload'.  Create a source tarball using 
+   % python setup.py clean
+   % python setup.py clean_cython
+   % python setup.py sdist
+  Add the source tarball to the 'upload' directory.
+* upload the release files to pypi with twine
+  (twine upload upload/*). This will require creating a ~/.pypirc
+  file with your pypi login credentials.
