15 New Features
16 ~~~~~~~~~~~~
17
18 - Implement a new 'notify-defer' configuration option. ``a24db6433e6``
19
20 This new option sets a delay (in seconds) to wait before sending a set
21 of NOTIFY messages for a zone. Whenever a NOTIFY message is ready to
22 be sent, sending will be deferred for this duration. This option is
23 not to be confused with the :any:`notify-delay` option. The default is
24 0 seconds. :gl:`#5259` :gl:`!10465`

26 Removed Features
27 ~~~~~~~~~~~~~~~~
28
29 - Implement the systemd notification protocol manually to remove
30 dependency on libsystemd. ``4f7e806a12b``
31
32 libsystemd, despite being useful, adds a huge surface area for just
33 using the sd_notify API. libsystemd's surface has been exploited in
34 the past [1].
35
36 Implement the systemd notification protocol by hand since it is just
37 sending newline-delimited datagrams to a UNIX socket. The code
38 shouldn't need more attention in the future since the notification
39 protocol is covered under systemd's stability promise [2].
40
41 We don't need to support VSOCK-backed service notifications since they
42 are only intended for virtual machine inits.

47 Bug Fixes
48 ~~~~~~~~~
49
50 - Fix zone deletion issue. ``66fc4ee86e0``
51
52 A secondary zone could initiate a new zone transfer from the primary
53 server after it had been already deleted from the secondary server,
54 and before the internal garbage collection was activated to clean it
55 up completely. This has been fixed. :gl:`#5291` :gl:`!10496`
56
57 - Fix a zone refresh bug. ``f09bb8b88c6``
58
59 A secondary zone could fail to further refresh with new versions of
60 the zone from a primary server if named was reconfigured during the
61 SOA request step of an ongoing zone transfer. This has been fixed.
62 :gl:`#5307` :gl:`!10495`
63
64 - Allow keystore.c to compile on Solaris. ``108adab25a0``
65
66 keystore.c failed to compile on Solaris because NAME_MAX was
67 undefined. Include 'isc/dir.h' which defines NAME_MAX for platforms
68 that don't define it. :gl:`#5327` :gl:`!10523`
69
70 - Set name for all the isc_mem contexts. ``bdcd698edf7``
71
72 :gl:`!10498`
