 # Changelog
 
+## [1.29.0] - Unreleased
+
+This new release of rustup comes with significant changes.
+
+The headline feature is better concurrency for certain operations,
+implemented by @FranciscoTGouveia within the scope of the GSoC 2025 event:
+
+- `rustup check` will check for toolchain updates concurrently. [pr#4388]
+
+- `rustup update` and `rustup toolchain` subcommands will download toolchain
+  components concurrently. [pr#4436] 
+
+  - You can use the `RUSTUP_CONCURRENT_DOWNLOADS` environment variable to
+    adjust the number of concurrent downloads to better reflect the needs of
+    your specific environment. [pr#4455]
+
+- `rustup` now uses `indicatif`-based progress bars for toolchain update
+  checks and downloads. This provides not only a more async-friendly UI solution,
+  but also a more consistent and visually appealing experience for various
+  commands like `rustup check`, `rustup update`, and `rustup toolchain install`.
+  [pr#4388] [pr#4426]
+
+rustup now officially supports the following host platforms:
+
+- `sparcv9-sun-solaris` [pr#4380]
+- `x86_64-pc-solaris` [pr#4380]
+
+This release also comes with other quality-of-life improvements, to name a few:
+
+- When running rust-analyzer via a proxy, rustup will consider the
+  `rust-analyzer` binary from `PATH` when the rustup-managed one is not found.
+  [pr#4324]
+
+- Empty environment variables are now treated as unset. This should help with
+  resetting configuration values to default when an override is present.
+  [pr#4422]
+
+- Basic support for the `tcsh` shell has been added. [pr#4459]
