+## [Unreleased]
+
+### Added
+- Functional Expressions API
+- Mathematical Syntax Tree, its interpreter and API
+- String to MST parser (https://github.com/mipt-npm/kmath/pull/120)
+- MST to JVM bytecode translator (https://github.com/mipt-npm/kmath/pull/94)
+- FloatBuffer (specialized MutableBuffer over FloatArray)
+- FlaggedBuffer to associate primitive numbers buffer with flags (to mark values infinite or missing, etc.)
+- Specialized builder functions for all primitive buffers like `IntBuffer(25) { it + 1 }` (https://github.com/mipt-npm/kmath/pull/125)
+- Interface `NumericAlgebra` where `number` operation is available to convert numbers to algebraic elements
+- Inverse trigonometric functions support in ExtendedField (`asin`, `acos`, `atan`) (https://github.com/mipt-npm/kmath/pull/114)
+- New space extensions: `average` and `averageWith`
+- Local coding conventions
+- Geometric Domains API in `kmath-core`
+- Blocking chains in `kmath-coroutines`
+
+### Changed
+- BigInteger and BigDecimal algebra: JBigDecimalField has companion object with default math context; minor optimizations
+- `power(T, Int)` extension function has preconditions and supports `Field<T>`
+- Memory objects have more preconditions (overflow checking)
+- `tg` function is renamed to `tan` (https://github.com/mipt-npm/kmath/pull/114)
+- Gradle version: 6.3 -> 6.5.1
+- Moved probability distributions to commons-rng and to `kmath-prob`.
+
+### Fixed
+- Missing copy method in Memory implementation on JS (https://github.com/mipt-npm/kmath/pull/106)
+- D3.dim value in `kmath-dimensions`
+- Multiplication in integer rings in `kmath-core` (https://github.com/mipt-npm/kmath/pull/101)
+- Commons RNG compatibility (https://github.com/mipt-npm/kmath/issues/93)
