go-ipfs 0.4.3 (opens new window) has been released today,
and we're incredibly proud as it's the fastest and most stable IPFS ever.
Give it a try as soon as you can, we're sure you'll like it as much as we do.

What's changed?

• Runtime performance has improved all over the place!
  Bitswap, Content Routing and Peer Routing, Datastore, Blockstore, you name it.
• Memory usage has improved as Provider records are now stored on disk.
• We now use Golang 1.7, which produces smaller and faster binaries.
• Connectivity between nodes is stabler than ever,
  as we fixed transport issues that were previously thought to be NAT-related.
• The go-ipfs daemon now automatically raises the limit of file descriptors if needed.
• The daemon now automatically runs fs-repo migrations.
• The daemon got new flags:
  • ipfs daemon --offline can be used to disable all swarm networking.
  • ipfs daemon --migrate automatically runs any pending fs-repo migrations.
• The Datastore got a few more config options:
  • Datastore.HashOnRead allows you to verify data on read access.
  • Datastore.BloomFilterSize tunes the new lookup cache.

And plenty of bug fixes as well as improvements to documentation and test coverage.
Take a look at the Changelog (opens new window).

How to upgrade

Depending on how you initially installed IPFS, there are several ways to
upgrade. If you installed IPFS with a pre-built binary, you can either head over
to dist.ipfs.tech (opens new window) and grab the latest version
from there. Or alternatively, from the same page you can grab the ipfs-update
binary, and use it to perform the upgrade for you. If you installed from
source, you can simply run git checkout v0.4.3, then run make install.

Please upgrade your IPFS nodes as soon as you can,
so you can take advantage of the improvements.
