# Note:  If you change the version, you must also update it in:
# * java/pom.xml
# * python/setup.py
# * src/google/protobuf/stubs/common.h
# * src/Makefile.am (Update -version-info for LDFLAGS if needed)
#
# In the SVN trunk, the version should always be the next anticipated release
# version with the "-pre" suffix.  (We used to use "-SNAPSHOT" but this pushed
# the size of one file name in the dist tarfile over the 99-char limit.)
