Synology has released DiskStation Manager Version: 6.1.4-15217-5 (aka DSM 6.1.4-1517 Update 5). This update follows up on last week’s confusing releases. If like me, you installed the repacked Update 3 rather than the original problem version then you’ll skip right over Update 4.
Update 5 contains only one fix and can be safely put off unless you have the problem and need it fixed. While no update is guaranteed to be 100% safe, updates don’t get much safer than this one.
The only fix is to resolve an issue where the scan results of Security Advisor may not be correct.
