BIRD 3.1.1 and 3.0.3 released

[Maria Matejka]

Hello Douglas,

Will happen, eventually, don't worry 🙃

Here you are. https://gitlab.nic.cz/labs/bird/-/blob/v3.1.1/doc/migration-bird3.md

>- Does it change syntax? Where? How much?

Not in conf, unless you do some low level table performance knobbing.

>- SMP, of course.
>- What else?

Partial route reimports and reexports on ROA updates, not much more iirc.

>- Who should be using it?

We are going to stop adding new features into BIRD 2 in some time, as BIRD 3 brings better refactored internal data structures.

>Another question I have and may be shared by other colleagues:
>What is the difference between v3.0 and v3.1? What are the plans for this
>type of release?

BIRD 3.1 NEWS file gives exactly this information:
  o CLI v2 compatibility layer for show route
  o Thread configuration rework
  o Merged 2.17

Version 2.17 (2025-04-01)
  o Babel: next hop control for IPv4
  o BGP: link-local next hop format configuration
  o TCP-AO implementation for Linux

Have a nice day!
Maria
