 ### Unreleased
 
+### v0.15.0
+
+#### Improvements
+
+- This is the first release supporting Elixir 1.15. See https://github.com/elixir-lsp/elixir-ls/pull/898 for details
+- Main distribution mode switched to `Mix.install` script. This allows running ElixirLS built with a correct combination of OTP and elixir. Previously used `.ez` releases suffered from numerous problems stemming from version incompatibilities (e.g. https://github.com/elixir-lsp/elixir-ls/issues/193)
+- elixir_sense replaced many of its custom source parsing internals with elixir 1.13+ Code.Fragment APIs
+- `require` and `import` are now understood by elixir_sense. This improves accuracy of definition, hover, references and complete providers. For example only imports matchin `only` and `except` options will now be suggested by complete provider.
+- When accepting a completion with a not required macro a `require` directive will be now added to module.
+- Better handling of typespecs in elixir_sense. This should improve accuracy in modules with defs and types sharing the same name.
+- Added ability to pass command line options to elixir and erlang via `ELS_ELIXIR_OPTS` and `ELS_ERL_OPTS`. This allows for setting a node name and connecting remotely to language server and debugger.
+
+#### Fixes
+
+- Fixed a longstanding bug with formatter not respecting `.formatter.exs` when code is compiling (requires elixir 1.15) [Thomas Depierre](https://github.com/DianaOlympos)
+- Fixed invalid alias handling with submodules
+
+#### Breaking changes and deprecations
+
+- Elixir 1.12 is no longer supported
+- `.ez` archive based distribution is now deprecated
+
 ### v0.14.6: 6 May 2023
