# Which Problems Are Solved https://github.com/zitadel/zitadel/pull/8788 accidentally changed the spelling of milestone types from PascalCase to snake_case. This breaks systems where `milestone.pushed` events already exist. # How the Problems Are Solved - Use PascalCase again - Prefix event types with v2. (Previous pushed event type was anyway ignored). - Create `milstones3` projection # Additional Changes None # Additional Context relates to #8788
