v0.6.0 (2018-??-??)

WCSLIB has been upgraded to v6.2. Note that now the obsgeo field of WCSTransform is a 6-element vector, instead of the previous 3-element vector. For backward compatibility, a 3-element vector can still be provided and it will be automatically adjusted.

v0.5.0 (2018-11-06)

WCSLIB has been upgraded to v5.20.

v0.4.0 (2018-09-16)

Drop support for Julia 0.6
The syntax to access properties of a WCSTransform object has been changed from wcs[:ctype] to the more familiar wcs.ctype. Likewise, the new syntax to set these properties is wcs.ctype = foo. The old syntaxes are still available but deprecated, they will be completely removed in a future version of the package.

v0.3.0 (2018-09-05)

Drop support for Julia 0.5
The relax keyword now defaults to accept all known non-standard keywords. The old default behavior can be obtained with relax=WCS.HDR_NONE.
Use BinaryProvider to install the binary dependency

v0.2.0 (2017-08-07)

Drop support for Julia 0.4
Clear deprecation warnings in Julia 0.6, master
Thread safety fix in WCSTransform()

v0.1.3 (2016-08-09)

Thread safety improvements: Added thread locks around header parsing functions (known to be thread unsafe); fix for race condition in world_to_pix and pix_to_world.
Added WCS.wcslib_version() function.
Fixed bug in throwing exceptions from WCSLIB.

v0.1.2 (2016-07-28)

Fix Julia v0.5 deprecation warnings

v0.1.1 (2016-02-07)

Relax world_to_pix and pix_to_world signatures to allow for single coordinate arguments.
Implement getindex for WCSTransform so that, for example, wcs[:ctype] returns the CTYPE attribute. This is consistent with the ability to set attributes with wcs[:ctype] = foo.

v0.1.0 (2016-02-04)

Initial release. WCS is a replacement for WCSLIB with a more Julian API.
