Need reviews who actually knows what happens with version regex in hindsight.

Need reviews who actually knows what happens with version regex in hindsight.

That check is done here.

termux-packages/scripts/updates/utils/termux_pkg_upgrade_version.sh

Lines 20 to 32 in 388cd7e

	# If needed, filter version numbers using grep regexp.
	if [[ -n "${TERMUX_PKG_UPDATE_VERSION_REGEXP:-}" ]]; then
	# Extract version numbers.
	local OLD_LATEST_VERSION="${LATEST_VERSION}"
	LATEST_VERSION="$(grep -oP "${TERMUX_PKG_UPDATE_VERSION_REGEXP}" <<< "${LATEST_VERSION}" || true)"
	if [[ -z "${LATEST_VERSION:-}" ]]; then
	termux_error_exit <<-EndOfError
	ERROR: failed to filter version numbers using regexp '${TERMUX_PKG_UPDATE_VERSION_REGEXP}'.
	Ensure that it works correctly with ${OLD_LATEST_VERSION}.
	EndOfError
	fi
	unset OLD_LATEST_VERSION
	fi

I personally think the variable names are a bit misleading, but the latest version number is compared against the PCRE specified in TERMUX_PKG_UPDATE_VERSION_REGEXP and the autoupdate is only allowed if the regex matches.

I do not know if the packages will be updated automatically when there is a newer 5.x.x version.

Assuming say a 5.117.0 release, yes they would.
As that will match the regex.
