NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

 $ bk prs README                  # print revision summary (newest first)
 $ bk prs -f README               # print revision summary (oldest first)
 $ bk prs -r+ README              # only most recent revision
 $ bk prs -r1.3 README            # specific revision
 $ bk prs -r1.3..1.6 README       # specific range of revisions
 $ bk prs -r1.5..+ README         # from specific revision to latest

bk prs also supports an output format and numerous keywords that let you customize exactly what output you want to see. For example, to list a file as of a particular revision:

 $ bk prs -r1.5 -n -d':GB:' README     # print revision 1.5 of file
 $ bk prs -r1.5 -nd':GB:' README       # shorter idiom of above

In addition to all of the above, bk prs has default and recursive behaviour:

 $ bk prs                      # all files in current directory
 $ bk -r prs                   # recursive (probably overkill)

In order to understand all of the possible options, you really need to consult the prs section of bk helptool.
