# Make targets:
#
#  all    : builds all binaries in development mode, without web assets (default)
#  full   : builds all binaries for PRODUCTION use
#  release: prepares a release tarball
#  clean  : removes all buld artifacts
#  test   : runs tests

# To update the Teleport version, update VERSION variable:
# Naming convention:
#	for stable releases we use "1.0.0" format
#   for pre-releases, we use   "1.0.0-beta.2" format
VERSION=2.5.0-rc.2
