Allows rejected routes to be kept and examined.
...
When 'import keep rejected' protocol option is activated, routes
rejected by the import filter are kept in the routing table, but they
are hidden and not propagated to other protocols. It is possible to
examine them using 'show route rejected'.

Better support for multitable protocols.
...
The nest-protocol interaction is changed to better handle multitable
protocols. Multitable protocols now declare that by 'multitable' field,
which tells nest that a protocol handles things related to proto-rtable
interaction (table locking, announce hook adding, reconfiguration of
filters) itself.
Filters and stats are moved to announce hooks, a protocol could have
different filters and stats to different tables.
The patch is based on one from Alexander V. Chernikov, thanks.

When uncofiguring the pipe and the peer table, the peer table was

the routes from the pipe were flushed.
The fix leads to adding some pipe-specific hacks to the nest,

Replace assert with log.
...
Although it is true unless there is a bug in BIRD, this assert is not
needed (code below does not require that assumption), so we should not
crash.

Fixes bug that caused losing of some routes.
...
When update changes preferred route in such a way that
it ceased to be preferred, the new route was linked
to wrong place and lost.

Fixes serious bug in route attribute handing.
...
ea_same() sometimes returns true for different route attributes,
which caused that hash table in BGP does not work correctly and
some routes were sent with different attributes.

A change in OSPF and RIP interface patterns.
...
Allows to add more interface patterns to one common 'options'
section like:
interface "eth3", "eth4" { options common to eth3 and eth4 };
Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:
interface "eth3" { options ... }, "eth4" { options ... };

Rewrite of buggy AS path matching.
...
Old AS path maching supposes thath AS number appears
only once in AS path, but that is not true. It also
contains some bugs related to AS path sets.
New code does not use any assumptions about semantic
structure of AS path. It is asymptotically slower than
the old code, but on real paths it is not significant.
It also allows '?' for matching one arbitrary AS number.

Fixes broken cryptographic authentication in OSPF
...
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.
That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

filtered by both EXPORT and IMPORT filters, but they should be
only filtered by EXPORT filters.

Better handling of AS4 optional attribute errors
...
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
- ignoring invalid AS4 optional attributes.
