Thanks Kevin.

Apart from release notes to identify changes of DPDK version from 19.11 to 21.11, is there any any major design changes in DPDK ? for example (memory management, mempool allocation behavior etc)

Please share if there is any pointers.

Thanks,

Kamaraj

If you are looking for an LTS version that will be maintained for the
longest time in the future, then you can jump to the latest DPDK LTS
series 21.11.

It will be maintained with backported bugfixes until at least November
2023, but we are trialing longer support on some LTS releases so there
is a possibility it might be extended.

If you take a look at http://core.dpdk.org/roadmap/#stable you can see
the current roadmap of how long each LTS version is maintained for.

thanks,
Kevin.
