Jul 1, 2026July 2026 monthly summary for thingsboard/thingsboard-edge: Strengthened data integrity and reliability in the tenant management path. Implemented immediate repository flush after saving a tenant to prevent database integrity violations and ensure consistent state across multi-tenant operations. This targeted robustness improvement reduces post-save reconciliation effort and supports safer onboarding of tenants. No external feature releases this month; the focus was on hardening core persistence and auditability to deliver long-term business value.
