Sentry 9 aims to improve the relevance of information displayed in the platform, reducing time to resolution, while making issue fixing less annoying for developers and teams involved. The new ownership features focus on increasing control over who owns what in projects, allowing teams and individuals to take action with that ownership. This shift prioritizes ensuring issues end up in the right hands as quickly as possible, rather than blaming specific engineers or teams for problems. The platform has also introduced new rules for defining paths or URLs that are owned by users or teams, making it easier to manage issue ownership and reduce noise.
