 # Changelog
 
+## [1.26.0] - unreleased
+
+This version of Rustup involves a significant number of internal refactors, both in terms
+of the Rustup code and its tests.
+
+The headlines for this release are:
+
+1. Add [rust-analyzer] as a [proxy] of rustup. Now you can call `rust-analyzer` and it will
+   be proxied to the rust-analyzer component for the current toolchain.
+2. Bump the [clap] dependency from 2.x to 3.x. It's a major version bump, so there are some
+   help text changes, but the command line interface is unchanged.
+
+In addition to a lot of work on the codebase itself, due to the length of time since the last
+release this one has a record number of contributors and we thank you all for your efforts and time.
+
+Rather than list every single merged PR since the last release, we have pulled out
+a number of highlights to include in this changelog entry. For everything else,
+please review the repository.
