Release notes

A patch release with important bug fixes and improved handling for storagetype.

Highlights

• Enhanced storagetype promotion system that robustly handles unions and abstract tensor map types (#370).
• Multiple truncation bug fixes improving reliability of truncation operations (#368, #369).
• small CUDA support improvements (#366).

Notable changes

Added

• A more robust promotion system for storagetypes to better handle working with unions and other abstract tensor map types (#370).

Fixed

• Fix findtruncated with truncspace to correctly handle truncation spaces (#369).
• Fix truncrank when kept rank is larger than input (#368).
• Added missing similar definition for SectorVector, improving compatibility and extensibility (#367).
• Small fixes for CUDA support, specifically ChainRules and constructor improvements (#366).

Upgrade notes

• This is a patch release; the public API remains compatible with v0.16.1.
• The improved storagetype promotion system may change behavior when mixing different storage types, but should generally be more correct and predictable.
