   - Security - The RFB specification (VNC) limits the password field to 8 characters, so while the client may take a longer password, only the first 8 characters are sent. KasmVNC defaults to HTTPS with HTTP Basic Auth and disables the legacy VNC authentication method which is not sufficiently secure for internet accessible systems.
   - Simplicity - KasmVNC aims at being simple to deploy and configure.
 
+# Releases
+
+Since this is a fast evolving project, the documents on the tip of master are chaning rapidly and will not match releases. Be sure to use the README and other documentation from the release branch that matches the version of KasmVNC you are using. Do not use the README from the master branch, unless you are compiling KasmVNC yourself from the tip of master. All releases starting at 0.9.3 have a branch named in the format 'release/0.9.3', for example.
