Nov 1, 2024

In November 2024, delivered a key feature enhancement in the IABTechLab/uid2-operator that simplifies token version allocation. The change removes explicit site ID overrides for V4 token assignment and bases token version on a predefined percentage of V4-capable tokens using a pseudo-random number generator. This reduces configuration complexity, improves consistency of token versioning across sites, and accelerates testing and deployment cycles. No major production bugs were reported; maintenance focus shifted toward refactoring and improving code readability. Overall, this work enhances predictability, reduces operational overhead, and supports faster iteration on token-versioning strategies.
