# helm-version automatically updates the versions of Helm charts to match the version set in the Makefile,
# so that chart versions are also kept in sync when the Teleport version is updated for a release.
# If the version contains '-dev' (as it does on the master branch, or for development builds) then we get the latest
# published major version number by parsing a sorted list of git tags instead, to make deploying the chart from master
# work as expected. Version numbers are quoted as a string because Helm otherwise treats dotted decimals as floats.
