+   * Integrate Easy-RSA TLS-Key for use with 'init-pki soft' (03d9dc2) (#1220)
+     Note: Inline files that contain private key data are now created in sub-dir
+     'pki/inline/private'.
    * easyrsa-tools.lib, show-expire: Add CA certificate to report (a36cd54) (#1215)
    * inline: OpenVPN TLS Keys inlining for TLS-AUTH, TLS-CRYPT-V1 (6e9e4a2) (#1185)
      Note: Command inline only writes directly to inline file not stdout.
