Changelog

1.29.0 - 2026-03-05

This new release of rustup comes with significant changes.

The headline feature is better concurrency for certain operations, implemented by @FranciscoTGouveia with the help from the team as a part of the GSoC 2025 event:

Improved the UX for the rustup update and rustup toolchain subcommands by downloading components concurrently and unpacking during downloads, which should speed up the toolchain installation process. Meanwhile, progress bars have been updated accordingly to and provide better feedback about where time is being spent. pr#4426 pr#4436 pr#4471 pr#4605
- 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 (the current default is 2). Particularly, you may set the value to 1 to restore the sequential downloading behavior. pr#4455
Improved the UX for the rustup check subcommand by checking for toolchain updates concurrently and updating the progress reporting UI. pr#4388

rustup now officially supports the following host platforms:

sparcv9-sun-solaris pr#4380
x86_64-pc-solaris pr#4380

In addition, basic support for more shells has been added, including:

tcsh pr#4459
xonsh pr#4626

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
rustup check will use different exit codes based on whether new updates have been found: it will exit with 100 on any updates or 0 for no updates. pr#4694

Furthermore, @FranciscoTGouveia has joined the team. He has shown his talent, enthusiasm and commitment to the project since the first interactions with rustup, so we are thrilled to have him on board and are actively looking forward to what we can achieve together.

1.28.2 - 2025-05-05

This new patch release has brought even more tiny fixes and improvements over the previous one.

The headlines of this release are:

The cURL download backend and the native-tls TLS backend are now officially deprecated and a warning will start to show up when they are used. pr#4277
- While rustup predates reqwest and rustls, the rustup team has long wanted to standardize on an HTTP + TLS stack with more components in Rust, which should increase security, potentially improve performance, and simplify maintenance of the project. With the default download backend already switched to reqwest since 2019, the team thinks it is time to focus maintenance on the default stack powered by these two libraries.
- For people who have set RUSTUP_USE_CURL=1 or RUSTUP_USE_RUSTLS=0 in their environment to work around issues with rustup, please try to unset these after upgrading to 1.28.2 and file an issue if you still encounter problems.
The version of rustup can be pinned when installing via rustup-init.sh, and rustup self update can be used to upgrade/downgrade rustup 1.28.2+ to a given version. To do so, set the RUSTUP_VERSION environment variable to the desired version (for example 1.28.2). pr#4259
rustup set auto-install disable can now be used to disable automatic installation of the toolchain. This is similar to the RUSTUP_AUTO_INSTALL environment variable introduced in 1.28.1 but with a lower priority. pr#4254
Fixed a bug in Nushell integration that might generate invalid commands in the shell configuration. Reinstalling rustup might be required for the fix to work. pr#4265
The logic of fetching the active toolchain's profile has been adjusted in automatic installation. Now, when the profile is not specified, the profile from rustup override set profile will be chosen instead of the profile named default. This aligns with the behavior of rustup toolchain install. pr#4258

1.28.1 - 2025-03-05

This is a patch release to restore the automatic install behavior by default.

This release contains the following fixes:

Automatic install is enabled by default but can be opted out by setting RUSTUP_AUTO_INSTALL environment variable to 0. pr#4214 pr#4227
rustup show active-toolchain will only print a single line, as it did in 1.27. pr#4221
Fixed a bug in the reqwest backend that would erroneously timeout downloads after 30s. pr#4218
Use relative symlinks for proxies. pr#4226

1.28.0 - 2025-03-04

This new release of rustup has been a long time in the making and comes with substantial changes.

The following improvements might require changes to how you use rustup:

rustup will no longer automatically install the active toolchain if it is not installed. pr#3985
- To ensure its installation, run rustup toolchain install with no arguments.
- The following command installs the active toolchain both before and after this change:
```
rustup show active-toolchain || rustup toolchain install
# Or, on older versions of PowerShell:
rustup show active-toolchain; if ($LASTEXITCODE -ne 0) { rustup toolchain install }
```
Installing a host-incompatible toolchain via rustup toolchain install or rustup default will now be rejected unless you explicitly add the --force-non-host flag. pr#4028

rustup now officially supports the following host platforms:

aarch64-pc-windows-msvc pr#3840
loongarch64-unknown-linux-musl pr#3921

This release also comes with various quality-of-life improvements, to name a few:

rustup show's output format has been cleaned up, making it easier to find out about your toolchains' status. pr#3225
rustup doc now accepts a flag and a topic at the same time, enabling quick navigation to specific parts of more books. pr#4070
rustup's remove subcommands now support more aliases such as rm and del. pr#4093
Basic support for nushell has been added. pr#4078

We have additionally made the following internal changes:

The default download backend has been changed from reqwest with native-tls to reqwest with rustls. pr#3798
- RUSTUP_USE_CURL and RUSTUP_USE_RUSTLS can still be used to change the download backend if the new backend causes issues. If issues do happen, please let us know.
- The default backend now uses rustls-platform-verifier to verify server certificates, taking advantage of the platform's certificate store on platforms that support it. pr#3903
When creating proxy links, rustup will now try symlinks first and fall back to hardlinks, as opposed to trying hardlinks first. pr#4023
A new RUSTUP_LOG environment variable can be used to control tracing-based logging in rustup binaries. See the dev guide for more details. pr#3875

Furthermore, Chris Denton joined the team. Chris has a lot of experience contributing to Windows-related parts of the Rust Project, expertise which was sorely lacking in existing team members, so we're happy to have him on board to help address Windows-specific issues.

Full Changelog: https://github.com/rust-lang/rustup/compare/1.26.0...1.27.0

1.26.0 - 2023-04-05

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:

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.
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.
Remove experimental GPG signature validation and the rustup show keys command. Due to its experimental status, validating the integrity of downloaded binaries did not rely on it, and there was no option to abort the installation if a signature mismatch happened. Multiple problems with its implementation were discovered in the recent months, which led to the decision to remove the experimental code. The team is working on the design of a new signature validation scheme, which will be implemented in the future.

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.

Added rust-analyzer as a proxy of rustup pr#3022
Added DisplayVersion for rustup to registry on Windows pr#3047
Build Rustup for Windows arm64 on stable pr#3232
Added up as an alias of the update command pr#3044

1.25.2 - 2023-02-01

This version of Rustup changes the signature verification code to continue accepting Rust's release signature key, which previously caused warnings due to a time-based check.

Note that signature verification in Rustup is still an experimental feature, and there is intentionally no way to enforce signature verification due to the feature being incomplete.

Thanks go to:

Pietro Albini
Daniel Silverstone

1.25.1 - 2022-07-12

This version of Rustup reverts a single PR from 1.25.1 and tidies a couple of internal bits of code.

In brief, it turns out that our optimisation for RUSTC and RUSTDOC cause problems with some tooling which runs under one cargo invocation, but expects to invoke either cargo or rustc without resetting the environment completely. As such, some particularly confusing error messages ensued, and we decided to revert this one optimisation while we wait to correct things in a future release.

Joshua Nelson
Manish Goregaokar

1.24.3 - 2021-05-31

This patch release focuses around resolving some regressions in behaviour in the 1.24.x series. One problem, related to accounting for the release of data blocks in the unpack slab allocator, fixed in pr#2779, would manifest in the installer hanging during installation. A second, fixed in pr#2781, manifested in very early Rust versions (1.0 through 1.7) repeatedly having their checksums fetched despite already being installed. Finally the heuristic which started warning that toolchains being installed may not work on the given host was improved in pr#2782 to reduce false-positive rate and reduce worry among Windows users in particular.

Added

Added the ability to configure the auto-self-update functionality. This will be of most use when people are testing unreleased versions of Rustup and wish to ensure they don't accidentally lose the test version, without having to remember to run with --no-self-update all the time. pr#2763

Changed

We no longer delete the top level of $RUSTUP_HOME/tmp and $RUSTUP_HOME/download meaning that if you have these set up as symlinks to another place, or bind mounts, etc. things should work. pr#2433
We more gracefully handle outlier situations with unpack-RAM, panicing less often, clamping settings into viable ranges and warning instead. pr#2780

1.24.2 - 2021-05-05

This patch release primarily exists to work around a problem discovered on some Windows (and potentially other) systems where a combination of factors, including suspected allocator behaviour, led to Rustup failing to install certain toolchains. The symptom users observed was a failure to allocate 1677732 bytes: a chunk used for unpacking very large files. We hope this is fixed in a combination of pr#2750 and pr#2756.

In addition to that, we also:

Added

SHA256 links on the download page so that you can verify your downloads if you want to be certain. pr#2719
Added --verbose to rustup show active-toolchain to also display the version of the compiler for the toolchain. pr#2710
We now support 1.x installation channel names for versions 1.0 through 1.8 by hardcoding 1.x.0 since they lack patch releases. pr#2758

Changed

Amended the behaviour of the 'missing components' code so that if the problem exists when installing a toolchain (rather than updating it) the message is different and leads you to other remediations. pr#2709
Amended the error message for a missing component so that when you're using a nightly toolchain and rust-std is missing for a given target, we lead you to cargo build -Z build-std as a remediation. pr#2732
Improved the documentation around settings.toml locations. pr#2698
Internal improvements around retrying removal of files. pr#2752

1.24.1 - 2021-04-27

This bugfix release corrects an oversight in the code we introduced to check for unknown proxy names. The original change accidentally omitted the rustfmt and cargo-fmt proxies due to a quirk of the fact those proxies were not originally part of a Rust component.

We're sorry for pain this may have caused.

1.24.0 - 2021-04-27

This release is mostly a bugfix and quality of life improvement release. However the headlines for this release are:

Support of rust-toolchain.toml as a filename for specifying toolchains.
Streaming support for large files to better enable Rust on lower memory platforms such as some Raspberry Pi systems.

When we introduced TOML support to rust-toolchain we expected to see some uptake but we saw a lot more than we had expected. Since Cargo is migrating to explicit .toml extensions on things like .cargo/config.toml it was considered sensible to also do this for rust-toolchain - at least the toml variant thereof.

This release of rustup has seen a significant number of new contributors to the project, and we hope to see many of you again in the future.

Added

Optional use of RUSTLS as TLS backend for Reqwest pr#2517
We now support some corner cases in tarballs to permit unpacking early Rust versions pr#2502
When running rustup check we now report possible rustup upgrades too. pr#2615
We detect and warn if you try and install on an x32 system since for now Rust isn't hostable on that. pr#2622
We do, however, support gnux32 as an environment label ready for future support pr#2631
We now support managing PATHs on Windows which contain non-unicode values. pr#2649
You can now name the TOML variant of rust-toolchain as rust-toolchain.toml pr#2653
We prompt harder when checking for the MSVC tooling on Windows now. pr#2529
Experimental support for zstd compressed tarballs in channels. NOTE, this does not mean channels will magically gain zstd compressed component files any time soon. pr#2676
Register rustup with the Windows installed programs list when installing. This is another experiment into whether this is useful for Windows users. pr#2670
Added the ability to specify a path rather than a toolchain channel in the rust-toolchain.toml file. pr#2678

Changed

rustup-init now detects tls1.2 for cURL 7.73+ pr#2604
Installation now indicates the defaults on all questions pr#2605
We now support the Big Sur major OS version pr#2607
You can now specify profile in rust-toolchain's TOML form pr#2586
We now use . instead of source to better support non-bash POSIX shells pr#2616
We fixed a nasty corner case on wildcarded component installation/recognition pr#2602
Our website now has a favicon pr#2419
We no longer rely on a broken mktemp invocation, this should make rustup-init.sh more compatible pr#2650
We now do a better job of reporting non-installable toolchains pr#2562
We cope better when modifying RC files which lack a trailing newline pr#2667
We are edging closer to requiring a specific force argument to install a toolchain whose host doesn't match the running system. This may break your CI in future so you should check carefully. The main use-case for this capability is the rust-embedded/cross project which we are working with to ensure this doesn't cause problems in the future. pr#2672
Support streaming large files during unpack phase. pr#2707
We report when you call rustup with an unsupported arg0 -- for example if you make a symlink or hard link to the binary with a name other than one of the proxies. pr#2716

We also cleaned up a number of error message cases, including some on invalid toolchain name pr#2613, a better message when no toolchain is installed pr#2657, and some on component unavailability pr#2619.

Documented

Added notes about Powershell to proxies documentation pr#2592
Various updates to the rustup manual build process including pr#2628
Small fixes on how to build rustup documentation pr#2641
We clarified the message around restarting the shell when installing pr#2684

1.23.1 - 2020-12-01

This point release is mostly to correct a problem where if you installed rustup with --no-modify-path then the .cargo/env file would not be created in some cases. In addition, we have rebuilt the macos binaries to correct an oversight which caused older Macs to be unable to run the new version. If you encountered a problem with liblzma on mac os 10.13 then this version should solve that for you.

Finally, the illumos binary is now part of the release properly.

1.23.0 - 2020-11-27

The main points for this release are that rustup now supports a number of new host platforms, most importantly of which is aarch64-apple-darwin for the new Apple M1 based devices, and that we support a new structured format for the rust-toolchain file. You can find more information in the new book format documentation.

It is now also possible to install a particular release of the compiler as a two-part version number. If you do this, then the release channel will only update if there is a patch release of the compiler. For example, if you ran rustup toolchain install 1.48 at the time of this release of rustup you would end up with a toolchain called 1.48 which contained 1.48.0. If subsequently 1.48.1 were released, a rustup update would update your 1.48 from 1.48.0 to 1.48.1.

As always, there were more changes than described below, thanks to everyone who contributed to this release. Highlights for this release are detailed below, but you can always see the full list of changes via the Git repository.

Added

Our documentation is now in "book" form. pr#2448
When you retrieve rustup's version, you'll also be told the version of the compiler for your default toolchain, to disambiguate things a little. pr#2465
Support added for aarch64-unknown-linux-musl pr#2493
Support added for aarch64-apple-darwin pr#2521
Support added for x86_64-unknown-illumos pr#2432
You can now override the system-wide settings fallback path pr#2545
Support for major.minor channels pr#2551

Changed

Significant updates to our handling of PATH updating on installation was made. Nominally this ought to have little external change visibility but it may make it more robust for some people. pr#2387
New support for toml-based rust-toolchain file format. This will be expanded upon going into the future to add new functionality, but for now the basics are in place, permitting you to select a channel, targets, and components which may be needed to build your applications. pr#2438
We now fall back to copying files when rename-in-place causes problems. This may improve matters in dockerised environments where rustup is preinstalled with a toolchain already. pr#2410
We do a better job of exiting gracefully in a number of circumstances. pr#2427
The reqwest backend (the default download backend) now supports socks5 proxies. pr#2466
If you use a proxy for a component which is not part of a custom toolchain you are using then we emit a message about trying to build that component. pr#2487
If you try and unpack super-large components which would previously be gracefully rejected, instead we try and if we succeed then you get to have the component unpacked. Unfortunately this means if we fail you could end up with a broken toolchain install. [pr#2490]
We will recommend ways to recover if you can't update your toolchain due to components or targets going missing. pr#2384
If you choose to install a toolchain which is for a different target than you are running on, we will warn you and direct you toward rustup target install in case that's what you meant. pr#2534

1.22.1 - 2020-07-08

A regression in proxied behaviour slipped in due to a non-compatible change in url slipping in in 2.1 which caused a misbehaviour in env_proxy. which was fixed but not released to crates.io until after 1.22.0 was built.

Fortunately, inejge noticed and provided a fix for us by publishing a new env_proxy and providing us with this fix.

We apologise for any inconvenience this caused.

Changed

Update to env_proxy 0.4.1 - #2399
Fixed website copy button and copy space overflow - #2398

Thanks

1.22.0 - 2020-06-30

Alongside a significant amount of internal refactoring and code updates, the highlights of this release include:

We have switched to Github Actions to make our CI and release process more consistent.
We've invested time in the flow when you reinstall rustup atop an existing installation.
We've doubled down on discouraging the use of the internal-development-focussed complete profile. Please use default or minimal unless you're trying to test/develop the Rust tooling itself.
We've made a number of subtle quality-of-life improvements around the CLI.
Added a (provisionally unofficial) snap of rustup
We've worked hard to improve a lot of the messages (error and informational) in the tool.
We've increased internal timeouts and retries in an attempt to improve the situation for McAfee users.
While it's not a change, we've documented that rust-toolchain must be UTF8 encoded.

While the changes spanned around 90 individual pull requests, here are the main changes and additions…

Changed

Fixed various links to our repo and to the forge - #2173
Improved OS detection (particularly darwin) in rustup-init.sh - #2042
Fixed bug where i686 installer on x86_64 windows would intend to install 64-bit but would actually install 32-bit toolchains by default. - #2186
Increased width of copy box on rustup website - #2208
When updating a toolchain, indicate the version you updated from as well. - #2152
When installing atop an existing rustup installation, we will now update the installed default toolchain, particularly we'll also try and install any additional targets or components specified - #2201 and #2339
Fixed issue where rustup doc wouldn't work with custom toolchains - #2235
In low-memory situations, attempt to unpack more conservatively - #2236
Improved consistency in where rustup will auto-install a toolchain on use. - #2252
Try to force strong cipher suites in rustup-init.sh - #2287
When skipping a nightly indicate all the missing components - #2316
Increase timeout for rename retries - #2348
Increased 'sanity limit' to account for MIPS binary size increases - #2363
Fallback to non-threaded installation pathway on 1-CPU systems to improve chance that installation will succeed on Raspberry Pi - #2372

Added

It is now possible to install rustup even when there's an existing rustup.sh installation, and we can install alongside rustc or cargo without necessarily forcing via -y by means of the RUSTUP_INIT_SKIP_EXISTENCE_CHECKS environment variable. - #2214
Added the concept of a fallback settings file which will allow snaps, distro packages, etc. to provide a default toolchain for users who have not passed through the rustup-init managed one-time question set. - #2244
You can now specify multiple components in a single argument in the form --component rls,rust-analysis,rust-src when installing toolchains - #2239
It is now possible to snap install --classic rustup in theory (channel details may take some time to settle) - #1898
Added indication of why overrides are happening when running rustup show - #2312
Added riscv64gc-unknown-linux-gnu support (note: There is still work to be done on the compiler etc before this will necessarily work) - #2313

1.21.1 - 2019-12-19

A panic occurred if a rustup update was run with nothing to update and the download directory was missing. This was harmless but could have confused some automation jobs.

1.21.0 - 2019-12-19

In release 1.20.x profiles could incorrectly ascribe host-independent components to the host architecture, resulting in surprising behaviour with rust-src. We have corrected this and added mitigations which should mean that as of this release, such incorrect ascriptions are supported and also automatically corrected on toolchain update.

Due to the large number of confusions around the complete profile, we have introduced a warning if you use it. It's really only meant for developers of Rust, or those exploring particular issues in nightly.

There are also a large number of other changes, the highlights of which are below. Thanks to everyone who helped work on this release. Even if your changes are not listed below, they are still greatly appreciated.

1.20.2 - 2019-10-16

One final tweak was needed to the force-installation of toolchains because otherwise components would be marked as installed when they were not.

Our apologies to anyone adversely affected by the 1.20.0/1 releases.

1.20.1 - 2019-10-16

This release was made to solve two problems spotted in 1.20.0

Force installation of toolchain during rustup-init to improve handling on non-tier-one platforms
Assume the default profile if a profile is missing from configuration which will solve a problem where distro-provided rustup binaries did not upgrade the configuration properly
