Change Log¶
Frequently Asked Questions¶
With a version like 0.x, is Hail ready for use in publications?¶
Yes. The semantic versioning standard uses 0.x (development) versions to refer to software that is either “buggy” or “partial”. While we don’t view Hail as particularly buggy (especially compared to one-off untested scripts pervasive in bioinformatics!), Hail 0.2 is a partial realization of a larger vision.
What stability is guaranteed?¶
We do not intentionally break back-compatibility of interfaces or file formats. This means that a script developed to run on Hail 0.2.5 should continue to work in every subsequent release within the 0.2 major version. The exception to this rule is experimental functionality, denoted as such in the reference documentation, which may change at any time.
Please note that forward compatibility should not be expected, especially relating to file formats: this means that it may not be possible to use an earlier version of Hail to read files written in a later version.

New features¶
(#11809) Export
dtypes_from_pandasinexpr.types(#11807) Teach smoothed_pdf to add a plot to an existing figure.

Bug fixes¶
(#11815) Fix incorrectly missing entries in to_dense_mt at the position of ref block END.

Several issues with the beta version of Hail Query on Hail Batch are addressed in this release.
Version 0.2.92¶
Release 2022-03-25
New features¶
(#11613) Add
