Release plans for GHC 7.8
- Dynamic GHCi (#3658). This is working in HEAD, and enabled if DYNAMIC_GHC_PROGRAMS=YES. Currently it's enabled by default if dynamic libraries are supported, except for FreeBSD and Windows.
On FreeBSD the reason it's disabled is due to a bug in FreeBSD's rtld. This has been fixed, but we're waiting for the fix to make it into releases. This might be in time for 7.8, but certainly will be for 7.10. See #7819.
On Windows, there are a couple of build time annoyances: -dynamic-too doesn't work on Windows, and linking takes a very long time when dynamic linking is used. There's no technical reason why it couldn't be enabled, though.
The plan is/was to use dynamic GHCi on as many platforms as possible in 7.8, and to remove support for non-dynamic-ghci in HEAD soon after. See discussion in #8039, however.
