Release 1.1.2 with WCSLIB 5.14 and also 1.0.9

[astrofrog]

As described in #4579 (comment), there is a major bug in the WCSLIB bundled with Astropy 1.1 and 1.1.1 which caused #4612. This is fixed in master by #4579 but should be backported to the 1.1.x and we should then release 1.1.2, since this is a bad bug (CRVAL1 gets truncated to ~arcminute precision!).

• Add regression test for WCS failure: CRVAL is truncated significantly #4612
• Add changelog entry
• Release 1.1.2

That sounds good to me!

wcslib-5.14 bundled in #4579 also fixes #4555. There's some additional work to be done in order to propagate the flags to/from astropy.wcs to wcslib. Since it's essentially the same type of problem it would be nice to fix it now. Does anyone have time to look into this?

[eteq]

@astrofrog - I've double checked and 1.0.8 seems to show none of these precision-bouncing effects.

[astrofrog]

See #4619 for a clarification of the changelog and another regression test.

[eteq]

Note that everything that should be seems to be backported to v1.1.x now, and the only holdout is that #4561 needs to get in to restore py2.6 compatibility.

[astrofrog]

@eteq - you mean #4641 right?

[eteq]

Oops, yeah, meant #4641 (which is a fix for #4561)

[eteq]

@astrofrog - OK, I think everything is backported that should be for 1.0.x and 1.1.x. And v1.1.x is passing: https://travis-ci.org/astropy/astropy/builds/112699046

We do need to do some changelog cleanup, though. I also think it would make sense to try to get #4650 in before a release, as it fixes some unintended consequences beyond astropy that were reported in #4633.

[eteq]

Also now v1.0.x is passing following a changelog tweak: https://travis-ci.org/astropy/astropy/builds/112746614

Current TBD before release:

• add missing check to ensure zest entry points aren't global #4650 or similar fix for zest.releaser hooks should be limited to astropy #4633
• Fix format conversion in the fast writer with plain format strings ('.2f') #4517 broke 2.6, so either get a fix in or back that out for this release
• Fix obs example for numpy 1.10 #4657 + changing the tested numpy to 1.10 (or maybe "stable"?)
• Clean up the changelog

Note that I also changed the title to do 1.0.9 at the same time. That will make the changelog easier anyway.

1.1.2 released! https://pypi.python.org/pypi/astropy/1.1.2
