v0.4.0

SUNRepresentations v0.4.0

Diff since v0.3.6

v0.4.0 of SUNRepresentations contains a large internal refactor of the data layout of SUNIrrep, going from NTuple{N, Int} (the weights), to NTuple{N - 1, UInt8} (the dynkin labels).
While the external behavior and interface should be untouched and contain no breaking changes, this does invalidate data that has been serialized, and therefore this release is cautiously marked as breaking.

• Change storagetype to UInt8 Dynkin labels to reduce memory footprint (#46) (@lkdvos)

Closed issues:

• [optimization] Reduce memory footprint by using UInt8 (#45)

v0.3.0

SUNRepresentations v0.3.0

Diff since v0.2.1

Version 0.3.0 comes with quite a few breaking changes to this package:

• TensorKit.jl is now no longer a dependency, and TensorKitSectors.jl is used instead. This enables the use of newer versions of TensorKit, simultaneously updating compatibility with TensorOperations and SparseArrayKit versions.
• Clebsch-Gordan coefficients are now no longer computed in bulk, which reduces the load for computing large irreps appearing in the expansion of s1 * s2, which are sometimes not used.
