Due to a large amount of spam we do not allow new users to create repositories, they are "external" users. If you are a new user and want to create a repository, for example for forking GHC, open a new issue on ghc/ghc using the "get-verified" issue template
Many issues in the wiki were unnecessarily links:
```
... patch posted in [\#1346](#1346).
```
This rewrites these as `#1346` using
```bash
sed -i -r -e 's/\[\\#([0-9]+)\]\([^)]+\/\1\)/#\1/g' $(find -iname '*.md')
```
And manually eyeballing the result.

-**Role support** - Richard Eisenberg implemented support for *role checking* in GHC, fixing a long standing bug [\#1496](https://gitlab.haskell.org/ghc/ghc/issues/1496) where `GeneralizedNewtypeDeriving` could be used to derive unsafe instances for a `newtype` (wiki \[Roles-wiki\] and paper \[Roles-paper\]).

-**New and improved I/O manager** - Earlier this year, Andreas Voellmy and Kazu Yamamoto worked on a host of improvements to our I/O manager, making it scale significantly better on multicore machines. Since then, it's seen some other performance tweaks, and many bugfixes. As a result, the new I/O manager should scale linearly up to about 40 cores. Andreas reports their McNettle Software-defined-network (SDN) implementation can now achieve over *twenty million connections per second*, making it the fastest SDN implementation around - an incredible feat!
