Jul 1, 2025July 2025 highlights for google/device-infra: Implemented a thread-safe memoized expiration cache for MoreSuppliers to enable robust value caching with defined expiration and proper exception handling from the delegate supplier. Refactored testbed configuration to support multiple values per dimension using ImmutableListMultimap, enhanced session-based results tracking, added a validation test suite, and introduced a flashstation configuration key. Per release hygiene, LAB_VERSION was bumped from 4.325.0 to 4.326.0 to reflect the minor internal release. These changes improve runtime efficiency, test reliability, and release traceability while aligning internal versioning.
