3.0.0, plus changes since 3.0.0rc0. All changes from 2.1.15 and below have been
incorporated.

Breaking changes:

  • Support for post-build metadata (__conda_version__.txt and the like) has been removed.
  • pin_downstream has been renamed to run_exports #1911
  • exclude_from_build_hash has been renamed to ignore_version #1911
  • Package signing and verification have been removed, to follow their removal from conda 4.3. #1950

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
  • 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
  • Check that files are executable when finding them #1899
  • 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
  • Avoid duplicate recreation of package index. Speedup of 0-50%, depending on how extensively the recipe uses Jinja2 features. #1954
  • Allow per-subpackage specification of target subdir #1961
  • Add basic environment marker support to conda skeleton pypi #1984
  • allow about section for each subpackage #1987
  • add support for optional dependencies (conda 4.4) #2001
  • fix windows entry point exe's for unicode #2045
  • allow strings for pin_run_as_build values (e.g. x.x) rather than just dictionaries #2042

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
  • 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
  • fix prefix file detection picking up too many files due to env recreation #1866
  • fix missing r_bin, make run_test.r scripts work #1869
  • 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
  • standardize entry point script template to match pip #1908
  • fix cleanup happening even when build fails #1909
  • fix bin/conda getting included in conda-build release tarballs #1913
  • 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
  • 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
  • Fix non-python packages creating python tests where they should not have #1967
  • Don't add python.app to run reqs multiple times #1972
  • Fix incorrect removal of cc in conda_interface.py #1971
  • Fix ORIGIN replacement - trailing slash was messing things up #1982
  • Pipe stdin when calling subprocess, in hopes of getting better ctrl-c handling with conda. #1986
  • Ensure that lock files are removed after build exit (or crash) to avoid permission errors on central installs #2002
  • Process line endings in bytes mode rather than text mode #2035
  • add a warning to find_recipe when multiple meta.yaml files are found (bioconda style) #2040
  • When applying patches, try 3 line ending options on the patch: 1. unchanged; 2. convert patch to unix line endings; 3. convert patch to windows line endings. #2052
  • fix empty target_platform variant entry leading to empty builds #2056
