Release notes for 1.9.0

[rossabaker]

Strictly speaking for semver, this could be a patch release, but I wanted to get people's attention since Scala 2.10 and Scala.js 0.6 are dropped. And since it's non-breaking for what does publish, I didn't want to go as far bumping the major version. So I compromised: minor bump.

[rossabaker]

Going to wait for #50 to build and give @sarahgerweck a chance to weigh in on the versioning or stop the presses. I'll aim to release tomorrow.

[sarahgerweck]

I'm happy enough with calling this a 1.9. @rossabaker if you want to finish releasing this please go ahead.

I've been trying to find time to catch up here but have a lot going on right now. Thanks for helping get this done.

I haven't forgotten. I've hit a snag on sbt release with MiMa. We can't run anything less than mima-0.6.1 on the upgraded SBT, and modern versions uncover some problems. Investigating:

The upgrade from Scala 2.12.6 to 2.12.8 in log4s-1.7.0 is responsible for the above error. It's not new, and nobody has complained, so I'm going to filter them to finish this release, and we can discuss what to do about it later.

[sarahgerweck]

@rossabaker ping me if this is getting too onerous. I probably couldn’t get into this until next week though.

[rossabaker]

I found that those are known false positives. I've worked around that, and am now wrestling with BouncyCastle. I also upgraded sbt-pgp. I think there is light at the end of this tunnel.

[rossabaker]

Success! I snuck in these two commits, which I hope are uncontroversial:

• d3dfcf2 sbt-mima-plugin-0.8.1
• 36452b3 sbt-pgp-2.0.1
