We're releasing a PATCH release of go-ipfs based on 0.4.21 containing some critical fixes.
The past several releases have been shaky and the network has scaled to the
point where where small changes can have a wide-reaching impact on the entire
network. To keep this situation from escalating, we've put a hold on releasing
new features until we can improve our [release

The IPFS network has scaled to the point where small changes can have a
wide-reaching impact on the entire network. To keep this situation from
escalating, we've put a hold on releasing new features until we can improve our
[release process](https://github.com/ipfs/go-ipfs/blob/master/docs/releases.md)
(which we've trialed in this release) and [testing
procedures](https://github.com/ipfs/go-ipfs/issues/6483).
This release includes fixes for the following regressions:
1. A major bitswap throughput regression introduced in 0.4.21
([ipfs/go-ipfs#6442](https://github.com/ipfs/go-ipfs/issues/6442)).
2. High bitswap CPU usage when connected to many (e.g.

complain about not being able to determine the IP address
([ipfs/go-ipfs#6415](https://github.com/ipfs/go-ipfs/pull/6415)).
It also includes fixes for:
1. Pins not being persisted after `ipfs block add --pin`
([ipfs/go-ipfs#6441](https://github.com/ipfs/go-ipfs/pull/6441)).
2.
C

on GC due to the pinner
([ipfs/go-ipfs#6419](https://github.com/ipfs/go-ipfs/pull/6419)).
2.
Panic due to c
oncurrent map access
when adding and listing pins at the same
time
([ipfs/go-ipfs#6419](https://github.com/ipfs/go-ipfs/pull/6419)).
3. Potential pin-set corruption given a concurrent `ipfs repo gc` and `ipfs pin
rm` ([ipfs/go-ipfs#6444](https://github.com/ipfs/go-ipfs/pull/6444)).
4. Build failure due to a deleted git tag in one of our dependencies
([ipfs/go-ds-badger#64](https://github.com/ipfs/go-ds-badger/pull/65)).
Thanks to:
* @hannahhoward for fixing both bitswap issues.
* @sanderpick for catching and fixing the local discovery bug.
* @campoy for fixing the build issue.
