 Clockwork follows a date-based year.month versioning scheme.
 
+## [2026.3] - 2026-03-20
+
+### Added
+
+- **DFL (Declarative Functional Language)**: New pure-functional sublanguage for runtime computations
+  - Expression syntax with arithmetic, comparison, and logical operators
+  - Conditional expressions: `if-then-else`, `cond`, and `match` with pattern matching
+  - User-defined template-style functions with optional type annotations
+  - Variadic function parameters and spread operator
+  - Built-in functions: `min`, `max`, `abs`, `clamp`, `sum`, `count`, `mean`, `any`, `all`, `map`, `filter`, `flatten`
+  - Trait system for type checking of operators
+  - Tuple/array literal syntax
+  - See [DFL Reference](clockwork/docs/reference/dfl/README.md) for details
+- **Struct-of-Arrays (SoA) Containers**: New `FixedSoa` and `VarSoa` container types for SoA data layout
+  - Memory-efficient alternative to `FixedArray`/`VarArray` that eliminates padding overhead
+  - `ElementRef` proxy provides AoS-style API while data is stored in SoA layout
+  - Direct field array access via `view_<field>()` methods for vectorization
+  - Full STL compatibility with iterators and algorithms
+  - Transparent schema evolution between AoS and SoA layouts
+  - See [SoA Containers Reference](clockwork/docs/reference/soa.md) for details
+- **State and Config Snapshot/Restore**: New mechanism for capturing and restoring Clockwork cog state and configuration (OI-3946).
+  - `TakeSnapshots` policy for periodic state snapshots with configurable intervals
+  - `SnapshotOnce` policy for one-time configuration snapshots at startup
+  - `FirstMessage` data source for loading state from logged snapshots
+  - `SerializedDataFile` enhancements for state restoration from files
+  - Support for fallback data sources when snapshots are unavailable
+  - See [Clockwork State/Config Snapshot/Restore Guide](clockwork/docs/reference/state_snapshot_and_restore.md) for details
+- **Unit Test Framework for Cogs**: Generated C++ cog unit-test wrappers for executing a cog in a unit test.
+  - See [Cog Unit Tests Reference](clockwork/docs/reference/cog_unit_tests.md) for details.
+- **Clockwork Observability Signals**: New support for generating scalar signals in a cog.
+  - Automatically aggregated and logged.
+  - Pre-aggregation and post-aggregation policies.
+  - Signal metadata publication and extraction tooling.
+  - See [Signals Reference](clockwork/docs/reference/signals.md) for details.
+- **Boilerplate Reduction in Schemas**: Simplify the generation syntax and build rules for Clockwork entities.
+  - New clk file syntax to specify code generation targets with attributes instead of defining them manually.
+  - Bazel rules implicitly create required targets for each Clockwork entity.
+  - Gazelle plugin to auto-generate build files from clk files.
+- New `@clockwork::std` standard library module (holds DSL entities used in user code, such as policies)
+
+### Changed
+
+- Updated Clockwork schemas to use new generator format.
+- Enhanced `LogicalSystemInterface` to support state restoration configuration in deterministic runner.
+- Expanded offboard logging observability with OpenTelemetry tracing instrumentation support (OI-4168).
+
 ## [2025.9] - 2025-09-30
