#1671 removed checking if we had an exact match for chip name before looking for partial chip names.
This broke all chips that are a substring of another chip.
It also removed a check for multiple exact matches, but I think that case is probably impossible as long as the registry doesn't have any duplicates.

Example:

$ probe-rs read b32 0x0 1 --chip Cortex-M3
Error: The chip 'Cortex-M3' was not found in the database.

Caused by:
    Found multiple chips matching 'Cortex-M3', unable to select a single chip. (Cortex-M33, Cortex-M35P)

This doesn't need a changelog entry IMO.
