0.2.11

pt, eta, phi, and mass caching on TLorentzVector.ArrayMethods now happens only at the deepest level of JaggedArray nesting. That means that short-lived views (projecting through a jagged table, for instance) won't invalidate that cache.

0.2.10

• Faster eta calculation.
• Some properties are memoized and constructing a TLorentzVector from pt, eta, phi, mass preloads the memo (so that mass from the TLorentzVector is exactly the same as the given mass, for instance).

0.2.9

sum() may now be used on physics vector arrays regardless of whether they're jagged or not.

0.2.8

Classmethod constructors for TLorentzVectorArray, TVector3Array, and TVector2Array (such as TLorentzVector.from_cartesian) accept jagged arrays as arguments, which result in JaggedArrayMethods of these arrays. Methods can be used at the jagged level, at the flat array level, or at the Python object level.

0.2.7

PR #9 fixed a bug in TVector3.cross (and added a test).

0.2.6

To get a Zenodo DOI.

0.2.5

@marinang added handling of TGraph types.

0.2.4

Fixed an infinite recursion bug for JaggedArrays of TLorentzVectors (code was general enough for ObjectArrayMethods but not also JaggedArrayMethods).

0.2.3

Fixed simple copy-paste errors in TLorentzVectorArray.from_ptetaphim and the from_p3 it depends on.

0.2.2

Fixed a bug in which TLorentzVectorArrays could not yield .p3 data if they were non-jagged.
