Version 2014.1.9 contained a regression which caused inaccurate Salt version detection, and thus was never packaged for general release. This version contains the version detection fix, but is otherwise identical to 2014.1.9.
Version 2014.1.10 is another bugfix release for 2014.1.0. Changes include:
.saltdirectory in salt-ssh
Salt 2014.1.10 fixes security issues documented by CVE-2014-3563: "Insecure tmp-file creation in seed.py, salt-ssh, and salt-cloud." Upgrading is recommended.
