 0.28.0 - Unreleased
 ===================
 
+Added
+-----
+
+- Many new third-party dependencies, which are all managed by Cargo. Future
+  updates to direct dependencies will be recorded in this changelog: the Git
+  history of ``Cargo.lock`` will provide a record of changes to the whole
+  dependency tree.
+
 Changed
 -------
 
-- :cpp:any:`loot::DatabaseInterface::LoadMasterlist()`,
-  :cpp:any:`loot::DatabaseInterface::LoadMasterlistWithPrelude()` and
-  :cpp:any:`loot::DatabaseInterface::LoadUserlist()` now throw
-  ``std::runtime_error`` exceptions instead of ``YAML::RepresentationException``
-  (which was a grandchild of ``std::runtime_error``) when there is a error
-  parsing metadata YAML.
-- When :cpp:any:`loot::DatabaseInterface::WriteUserMetadata()` or
-  :cpp:any:`loot::DatabaseInterface::WriteMinimalList()` are called with an
-  output path that has a parent path that does not exist, they now throw a
-  ``std::runtime_error`` instead of a ``std::invalid_argument``.
-- When :cpp:any:`loot::DatabaseInterface::GetGroupsPath()` is given a group name
-  that is undefined, it now throws a :cpp:any:`loot::UndefinedGroupError`
-  instead of a ``std::invalid_argument``.
-- Many exception messages have changed.
+- Most of libloot has been reimplemented in Rust instead of C++, with the C++
+  API now a thin wrapper around the Rust implementation. The C++ ABI and the
+  documented C++ API are unchanged, though there have been changes to many of
+  the exceptions that are thrown when errors are encountered.
