4.8.0

What's new in this release:

• coverage fixes and new build matrix for ROOT for CI
• support python 3.7 (with new cython)
• fix typos in docs

4.7.3

What's new in this release:

• silence cling errors in nosetests
• documentation improvements
• ignore duplicate keys with different cycles in list_objects
• additional improvements related to a code review for the JOSS paper submission

4.7.2

What's new in this release:

• The tests were missing from 4.7.1 and have been re-included

4.7.1

What's new in this release:

• Switched from MIT to new BSD license
• The branches argument for tree2array and root2array can contain tuples of the form (branch_or_expression, fill_value, length) that allow you to truncate variable-length branches or expressions at a fixed length or single value (if length==1 or omitted) while imputing missing values where the original subarray was shorter than length with fill_value.

4.6.0

What's new in this release:

• Make numpy a requirement only if not already installed
• Support new TMVA DataLoader API
• hist2array: return_edges=True returns the bin edges along each axis
• stretch: if fields is single string (not a list) then flatten output
• tree2array and root2array: added new object_selection argument to perform selection on variable-length subarrays

Bugfixes:

• Fix rec2array shape consistency for subarrays
• Reset branch addresses after conversion in array2tree

4.4.0

What's new in this release:

tree2array:

• Enable tree caching and add cache_size argument
• Fix integer overflow in handling of trees with more than 2^31 entries
• More informative MemoryError if array is too large to fit in memory
• Consider start and stop arguments in initial array allocation to avoid filling memory when reading a large tree in chunks

4.3.0

What's new in this release:

• Added support for strings and fixed-size multidimensional subarrays of basic types in array2tree and array2root.

4.2.1

What's new in this release:

• This is a minor release with minor improvements made to hist2array and stretch.

4.2.0

What's new in this release:

• The internals of tree2array have been rewritten
• Conversion speed of trees with many branches is significantly improved
• tree2array handles multidimensional arrays (fixed and variable size)
