+# Changelog
+
+## Unreleased
+
+### Compiler
+
+- The compiler will now show "Unused variable" warning for each of alternative
+  patterns.
+  ([Andrey Kozhev](https://github.com/ankddev))
+
+### Build tool
+
+- `gleam remove` now rejects invalid package names with an error explaining
+  naming rules, instead of stating that the package is not a dependency.
+  Trying to remove `gleam_otp@1` now suggests the matching dependency
+  `gleam_otp`, if there is one.
+  ([Tom Voet](https://github.com/tomvoet))
+
+- When Hex dependencies change version the build tool now prints a link to the
+  diff on Hex, making it easier to review and audit dependency updates.
+  ([Manas Ganesh Dasari](https://github.com/ManasDasri))
+
+- The Hex files page will now be used for the view-source link in generated
+  documentation when the package's source repository uses an unknown forge or
+  is not set.
+  ([Alex Hinde](https://github.com/apex-hinde))
+
+- The Hex credentials file is now written with read-write permissions for the
+  owner only (0600 on Unix), preventing other users from reading it.
+  ([bala-bhargav](https://github.com/bala-bhargav))
+
+### Language server
+
+- The language server will now offer "Discard unused variable" on each of
+  alternative patterns.
+  ([Andrey Kozhev](https://github.com/ankddev))
+
+- The language server now allows to find references of `echo`. For example,
+
+  ```gleam
+  pub fn wibble(woo) {
+    echo woo
+  //^^^^
+    echo wobble(woo)
+  //^^^^
+  }
+
+  pub fn wobble(woo) {
+    echo woo
+  //^^^^
+  }
+  ```
+
+  When triggering on any of denoted places, it will show all usages.
+  ([Andrey Kozhev](https://github.com/ankddev))
+
+- The language server now allows to highlight all `echo` in file. For example,
+
+  ```gleam
+  pub fn wibble(woo) {
+    echo woo
+  //^^^^
+    echo wobble(woo)
+  //^^^^
+  }
+
+  pub fn wobble(woo) {
+    echo woo
+  //^^^^
+  }
+  ```
+
+  If this feature is enabled in your editor, hovering any of denoted places will
+  highlight all of them.
+  ([Andrey Kozhev](https://github.com/ankddev))
+
+- The language server now allows to find references of `todo`. For example,
+
+  ```gleam
+  pub const wubble = todo
+  //                 ^^^^
+
+  pub fn wibble() {
+    todo as "unimplemented yet"
+  //^^^^^^^^^^^^^^^^^^^^^^^^^^^
+  }
+
+  pub fn empty() {}
+  //^^^^^^^^^^^^ Empty functions are shown too!
+
+  pub fn block() {
+    {}
+  //^^ And empty blocks too!
+  }
+  ```
+
+  When triggering on any of denoted places, it will show all usages.

+  ([Andrey Kozhev](https://github.com/ankddev))
+
+- The language server now allows to find references of `panic`. For example,
+
+  ```gleam
+  pub fn wibble() {
+    panic
+  //^^^^^
+  }
+
+  pub fn wobble() {
+    panic as "unimplemented"
+  //^^^^^^^^^^^^^^^^^^^^^^^^
+  }

+  duplicate module name when triggered on qualified values.

+  package with no README on Windows.
