########################################################################

# Update the below when releasing a new version
BOLT_VERSION=1.0a1

# Produce a numeric version assuming the following format:
# Version: [MAJ].[MIN].[REV][EXT][EXT_NUMBER]
# Example: 1.0.7rc1 has
#          MAJ = 1
#          MIN = 0
#          REV = 7
#          EXT = rc
#          EXT_NUMBER = 1
#
# Converting to numeric version will convert EXT to a format number:
#          ALPHA (a) = 0
#          BETA (b)  = 1
#          RC (rc)   = 2
#          PATCH (p) = 3
# Regular releases are treated as patch 0
#
# Numeric version will have 1 digit for MAJ, 2 digits for MIN,
# 2 digits for REV, 1 digit for EXT and 2 digits for EXT_NUMBER.
