-## [Unreleased]
+## [2.0.0]
 
 ### Changed
 
 - **BREAKING**: `ConfigurationStore::getConfiguration()` now returns `std::shared_ptr<const Configuration>` instead of `Configuration` by value
   - Returns an empty configuration when no configuration is set (graceful behavior, no null checks required)
-  - Eliminates expensive configuration copies on every flag evaluation
-  - Provides thread-safe reference counting via `std::shared_ptr`
   - Configuration is immutable (`const`) once retrieved
   - Update your code: use `->` instead of `.` to access configuration methods (no null checks needed)
+- **BREAKING**: All error handling is now done through logging and returning default values
+- **BREAKING**: Removed `setIsGracefulFailureMode()` method - SDK always operates in "graceful" mode
+- **BREAKING**: Removed custom exception classes (`FlagConfigurationNotFoundException`, `FlagNotEnabledException`, `SubjectAllocationException`)
+- **BREAKING**: `EppoClient` constructor now takes `ConfigurationStore&` by reference instead of `std::shared_ptr<ConfigurationStore>`, allowing SDK consumers to choose their own synchronization strategy
+- SDK now builds with `-fno-exceptions` and does not use exceptions internally
+- Configured nlohmann/json with `JSON_NOEXCEPTION` to eliminate JSON parsing exceptions
+- Constructor preconditions (null checks, size validations) now use `assert()` instead of throwing exceptions
+- Internal functions now return `std::optional` or error codes instead of throwing exceptions
+
+### Added
+
+- Full compatibility with `-fno-exceptions` projects
+- Documentation on error handling and constructor preconditions
+
+### Migration Guide
+
+If you were using v1.0.0:
+
+1. Remove all `try-catch` blocks around SDK method calls - they no longer throw
+2. Remove calls to `setIsGracefulFailureMode()` - this method no longer exists
+3. Update `EppoClient` instantiation - pass `ConfigurationStore` by reference instead of as `shared_ptr`:
+   - Before: `auto client = std::make_shared<EppoClient>(configStorePtr);`
+   - After: `EppoClient client(configStore);` (ensure `configStore` outlives `client`)
+4. Ensure constructor preconditions are met (non-null loggers, positive cache sizes)
+5. Monitor errors through the `ApplicationLogger` interface instead of catching exceptions
