Conda-build

Breaking changes:
-----------------

* Package signing and verification have been removed, to follow their removal from conda 4.3. 1950

Enhancements:
-------------

* Avoid duplicate recreation of package index. Speedup of 0-50%, depending on how extensively the recipe uses Jinja2 features. 1954

Bug Fixes:
----------

* Fix cleanup of folders in outer variant loop - was causing incorrect packages on 2nd variant in windows builds 1950
* Remove variant functionality from bdist_conda. Its split packaging approach is incompatible. 1950
* Fix import of _toposort from conda, reroute through conda_interface 1952
* Match folder substrings more intelligently, for finding previous builds with --dirty 1953
* Fix type error with --skip-existing and some conda recipes (Conda-build's internal conda.recipe was one). 1956

Breaking changes:
-----------------

* pin_downstream has been renamed to run_exports 1911
* exclude_from_build_hash has been renamed to ignore_version 1911

Enhancements:
-------------

* use rm_rf to remove prefixes for more cleanliness and better speed 1915
* add support for multiple sources in one meta.yaml 1929
* allow ``exact`` keyword for pin_compatible jinja2 function 1929
* allow selectors in variant conda_build_config.yaml files 1937

Bug fixes:
----------

* fix mmap/file problems on virtualbox shared folders 1914
* Correct rendering with --dirty flag if recipe name appears as substring of another's name 1931
* don't set language env vars (PERL, R, LUA, PYTHON) when those packages are not installed 1932
* exclude language env vars from variant being set 1944

Breaking changes:
-----------------

* Support for post-build metadata (__conda_version__.txt and the like) has been removed.

Enhancements:
-------------

* use symlinks when copying to improve performance 1867
* load setup.cfg data in load_setup_py_data 1878
* calculate checksum and simplify cran skeleton 1879

Bug fixes:
----------

* fix R's binary path on Windows 1870
* remove tab completion on CLI for compatibility with conda 4.4 1795
* reduce scope of git try/except block so that GIT_FULL_HASH is available, even if tags are not 1873
* Fix "compiler" jinja2 looping, so that it is respected in subpackages 1874
* Fix license family comparison - case matching 1875
* Fix inspect linkages when multiple packages contain a library 1884
* avoid unnecessary computation of hashing 1888
* fix python imports not being run in test phase 1896
* fix path omission in paths.json for noarch packages 1895

Bug fixes:
----------

* remove build and test envs after each packaging step, to avoid unsatisfiable errors 1866
* remove version pins from requirements added by run_test files (again avoid unsatisfiable errors) 1866

This is a complete revolution in the dynamic rendering capabilities of conda-build. More information is in the docs PR at https://github.com/conda/conda-docs/pull/414. There will be a blog post soon, perhaps coupled with a screencast.

Enhancements:
-------------

* greatly extended Jinja2 templating capabilities 1585
* record environment variables at top of build.sh, similar to what is done with bld.bat in win. 1765

Bug fixes:
----------

* fix symlinks to folders in packaging 1775
* fix detection of patch level when maxlevel=0 1796
* properly copy permissions when extracting zip files 1855
* Add more important Windows environment variables to the test environment 1859, 1863
