This release contains general and security-only bulletins. Security-only bulletins are applicable to new security fixes only. No new bug fixes are included, but bug fixes from prior patch/update releases are included.

If the installation of all new security and bug fixes is required, you must apply all bulletins in this release. In some cases, the general release bulletin will supersede the security- only bulletin. This is not an issue as the general release bulletin contains both the new security and bug fixes.

The bulletin IDs of security-only bulletins end with an “SG” suffix.
