+# Change Log
+
+## 0.2.0 - unreleased
+
+### Added
+
+- Implement `IntoIterator` for `IpCidr` structs
+- Support (and require) various default traits
+- `InetPair`: pair of two addresses in the same network
+- Implement "trait" functions directly on data types and only forward in trait impl (#6); this makes it easier to use datastructs without traits in scope.
+
+### Changed
+
+- Made `bitstring` dependency optional. Use `cidr = { version = "0.2.0", features = [ "bitstring" ] }` to enable it.
+- Removed `serde` from default features. Use `cidr = { version = "0.2.0", features = [ "serde" ] }` to enable it.
+- Added `std` feature; enabled by default.  Also mandatory for now as `std::net` isn't available in `core`.
+- Seal trait implementations
+- Renamed `Inet::next` to `Inet::increment`
+- Iterators (on `IpCidr` structs) now return `Inet` items instead of flat addresses. Use `.addresses()` on the iterator type to only iterate over the addresses.
