v5.4.0

TensorOperations v5.4.0

Diff since v5.3.1

This minor release contains a number of compat version updates, especially for cuTENSOR and CUDA.
Additionally, the automatic differentiation support has been improved to better support second order derivatives, along with a number of performance improvements.

v5.3.0

TensorOperations v5.3.0

Diff since v5.2.1

This minor version release includes some small fixes, but most importantly changes the precompilation from being opt-out to opt-in. This is mostly because it can take a substantial amount of time, and some users have ran into issues where the precompilation hangs indefinitely, especially on certain cluster architectures.

Merged pull requests:

• Add more descriptive errors to ncon (#216) (@VictorVanthilt)
• Add logo compatible with darkmode (#218) (@VictorVanthilt)
• Avoid using strings in nconstyle checks and errors (#219) (@lkdvos)

v5.2.1

Diff since v5.2.0

Merged pull requests:

• [Fix] makeblascontractable should return blascontractable objects. (#210) (@lkdvos)
• Clean up cuTENSOR plan memory (#212) (@lkdvos)

Closed issues:

• Enable to perform this operation (#209)
• Potential memory leak for cuTENSOR contractions with minimal example (#211)

v5.2.0

TensorOperations v5.2.0

Diff since v5.1.4

v5.2.0 attempts to improve the overall user experience by including some precompilation for the main methods of this package. For now, this is limited to Array{Float64} or Array{ComplexF64} to not overburden the precompilation time, and we'll be monitoring the implications and adjust accordingly if necessary.

Merged pull requests:

• Add precompile statements (#203) (@lkdvos)
• Add aliasing warning to docs (#204) (@lkdvos)
• optimaltree hangs on edge case with all costs equal to 1 (#207) (@lkdvos)

Closed issues:

• Incorrect result when using input tensor to store result of contraction involving sum (#192)
