synopsis: "Rust nix-installer in beta"
prs: []
---
The Rust-based rewrite of the Nix installer is now in beta.
We'd love help testing it out!
To test out the new installer, run:
```
curl -sSfL https://artifacts.nixos.org/nix-installer | sh -s -- install
```
This installer can be run even when you have an existing, script-based Nix installation without any adjustments.
This new installer also comes with the ability to uninstall your Nix installation; run:
```
/nix/nix-installer uninstall
```
This will get rid of your entire Nix installation (even if you installed over an existing, script-based installation).
This installer is a modified version of the [Determinate Nix Installer](https://github.com/DeterminateSystems/nix-installer) by Determinate Systems.
Thanks to Determinate Systems for all the investment they've put into the installer.
Source for the installer is in https://github.com/NixOS/nix-installer.
Report any issues in that repo.
For CI usage, a GitHub Action to install Nix using this installer is available at https://github.com/NixOS/nix-installer-action.

Channel URLs have been updated from `https://nixos.org/channels/` to `https://channels.nixos.org/` throughout Nix.
The subdomain provides better reliability with IPv6 support and improved CDN distribution. The old domain apex (`nixos.org/channels/`) currently redirects to the new location but may be deprecated in the future.

synopsis: "New setting `ignore-gc-delete-failure` for local stores"
prs: [15054]
---
A new local store setting [`ignore-gc-delete-failure`](@docroot@/store/types/local-store.md#store-local-store-ignore-gc-delete-failure) has been added.
When enabled, garbage collection will log warnings instead of failing when it cannot delete store paths.
This is useful when running Nix as an unprivileged user that may not have write access to all paths in the store.
This setting is experimental and requires the [`local-overlay-store`](@docroot@/development/experimental-features.md#xp-feature-local-overlay-store) experimental feature.

synopsis: "JSON format changes for store path info and derivations"
prs: []
issues: []
---
JSON formats for store path info and derivations have been updated with new versions and structured fields.
## Store Path Info JSON (Version 2)
The store path info JSON format has been updated from version 1 to version 2:
- **Added `version` field**:
All store path info JSON now includes `"version": 2`.
- **Structured `ca` field**:
Content address is now a structured JSON object instead of a string:
- Old: `"ca": "fixed:r:sha256:1abc..."`
- New: `"ca": {"method": "nar", "hash": {"algorithm": "sha256", "format": "base64", "hash": "EMIJ+giQ..."}}`
- Still `null` values for input-addressed store objects
- **Structured hash fields**:
Hash values (`narHash` and `downloadHash`) are now structured JSON objects instead of strings:
- Old: `"narHash": "sha256:FePFYIlMuycIXPZbWi7LGEiMmZSX9FMbaQenWBzm1Sc="`
- New: `"narHash": {"algorithm": "sha256", "format": "base64", "hash": "FePFYIlM..."}`
- Same structure applies to `downloadHash` in NAR info contexts
Nix currently only produces, and doesn't consume this format.
**Affected command**: `nix path-info --json`
## Derivation JSON (Version 4)
The derivation JSON format has been updated from version 3 to version 4:
- **Restructured inputs**:
Inputs are now nested under an `inputs` object:
- Old: `"inputSrcs": [...], "inputDrvs": {...}`
- New: `"inputs": {"srcs": [...], "drvs": {...}}`
- **Consistent content addresses**:
Floating content-addressed outputs now use structured JSON format.
This is the same format as `ca` in in store path info (after the new version).
Version 3 and earlier formats are *not* accepted when reading.
**Affected command**: `nix derivation`, namely it's `show` and `add` sub-commands.

synopsis: Fix "download buffer is full; consider increasing the 'download-buffer-size' setting" warning
prs: [14614]
issues: [11728]
---
The underlying issue that led to [#11728](https://github.com/NixOS/nix/issues/11728) has been resolved by utilizing
[libcurl write pausing functionality](https://curl.se/libcurl/c/curl_easy_pause.html) to control backpressure when unpacking to slow destinations like the git-backed tarball cache. The default value of `download-buffer-size` is now 1 MiB and it's no longer recommended to increase it, since the root cause has been fixed.
This is expected to improve download performance on fast connections, since previously a single slow download consumer would stall the thread and prevent any other transfers from progressing.
Many thanks go out to the [Lix project](https://lix.systems/) for the [implementation](https://git.lix.systems/lix-project/lix/commit/4ae6fb5a8f0d456b8d2ba2aaca3712b4e49057fc) that served as inspiration for this change and for triaging libcurl [issues with pausing](https://github.com/curl/curl/issues/19334).

Added support for `tls-certificate` and `tls-private-key` options in substituter URLs.
Example:
```
https://substituter.invalid?tls-certificate=/path/to/cert.pem&tls-private-key=/path/to/key.pem
```
When these options are configured, Nix will use this certificate/private key pair to authenticate to the server.

synopsis: New command `nix store roots-daemon` for serving GC roots
prs: [15143]
---
New command [`nix store roots-daemon`](@docroot@/command-ref/new-cli/nix3-store-roots-daemon.md) runs a daemon that serves garbage collector roots over a Unix domain socket.
It enables the garbage collector to discover runtime roots when the main Nix daemon doesn't have `CAP_SYS_PTRACE` capability and therefore cannot scan `/proc`.
The garbage collector can be configured to use this daemon via the [`use-roots-daemon`](@docroot@/store/types/local-store.md#store-experimental-option-use-roots-daemon) store setting.
This feature requires the [`local-overlay-store` experimental feature](@docroot@/development/experimental-features.md#xp-feature-local-overlay-store).

S3 binary cache operations now happen via HTTP, leveraging `libcurl`'s native
AWS SigV4 authentication instead of the AWS C++ SDK, providing significant
improvements:
- **Reduced memory usage**: Eliminates memory buffering issues that caused
segfaults with large files
- **Fixed upload reliability**: Resolves AWS SDK chunking errors
(`InvalidChunkSizeError`)
- **Lighter dependencies**: Uses lightweight `aws-crt-cpp` instead of full
`aws-cpp-sdk`, reducing build complexity
The new implementation requires curl >= 7.75.0 and `aws-crt-cpp` for credential
management.
All existing S3 URL formats and parameters remain supported, however the store
settings for configuring multipart uploads have changed:
- **`multipart-upload`** (default: `false`): Enable multipart uploads for large
files. When enabled, files exceeding the multipart threshold will be uploaded
in multiple parts.
- **`multipart-threshold`** (default: `100 MiB`): Minimum file size for using
multipart uploads. Files smaller than this will use regular PUT requests.
Only takes effect when `multipart-upload` is enabled.
- **`multipart-chunk-size`** (default: `5 MiB`): Size of each part in multipart
uploads. Must be at least 5 MiB (AWS S3 requirement). Larger chunk sizes
reduce the number of requests but use more memory.
- **`buffer-size`**: Has been replaced by `multipart-chunk-size` and is now an alias to it.
Note that this change also means Nix now supports S3 binary cache stores even
if built without `aws-crt-cpp`, but only for public buckets which do not
require authentication.

synopsis: "S3 binary cache stores now support storage class configuration"
prs: [14464]
issues: [7015]
---
S3 binary cache stores now support configuring the storage class for uploaded objects via the `storage-class` parameter. This allows users to optimize costs by selecting appropriate storage tiers based on access patterns.
Example usage:
```bash
# Use Glacier storage for long-term archival
nix copy --to 's3://my-bucket?storage-class=GLACIER' /nix/store/...
# Use Intelligent Tiering for automatic cost optimization
nix copy --to 's3://my-bucket?storage-class=INTELLIGENT_TIERING' /nix/store/...
```
The storage class applies to both regular uploads and multipart uploads. When not specified, objects use the bucket's default storage class.
See the [S3 storage classes documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html) for available storage classes and their characteristics.

synopsis: S3 binary caches now use virtual-hosted-style addressing by default
issues: [15208]
---
S3 binary caches now use virtual-hosted-style URLs
(`https://bucket.s3.region.amazonaws.com/key`) instead of path-style URLs
(`https://s3.region.amazonaws.com/bucket/key`) when connecting to standard AWS
S3 endpoints. This enables HTTP/2 multiplexing and fixes TCP connection
exhaustion (TIME_WAIT socket accumulation) under high-concurrency workloads.
A new `addressing-style` store option controls this behavior:
- `auto` (default): virtual-hosted-style for standard AWS endpoints, path-style
for custom endpoints.
- `path`: forces path-style addressing (deprecated by AWS).
- `virtual`: forces virtual-hosted-style addressing (bucket names must not
contain dots).
Bucket names containing dots (e.g., `my.bucket.name`) automatically fall back
to path-style addressing in `auto` mode, because dotted names create
multi-level subdomains that break TLS wildcard certificate validation.
Example using path-style for backwards compatibility:
```
s3://my-bucket/key?region=us-east-1&addressing-style=path
```
Additionally, TCP keep-alive is now enabled on all HTTP connections, preventing
idle connections from being silently dropped by intermediate network devices
(NATs, firewalls, load balancers).

## Evaluation order
The order in which expressions are evaluated is generally unspecified, because it does not affect successful evaluation outcomes.
This allows more freedom for the evaluator to evolve and to evaluate efficiently.
Data dependencies naturally impose some ordering constraints: a value cannot be used before it is computed.
Beyond these constraints, the evaluator is free to choose any order.
The order in which side effects such as [`builtins.trace`](@docroot@/language/builtins.md#builtins-trace) output occurs is not defined, but may be expected to follow data dependencies. <!-- we may want to be more specific about this. -->
In a lazy language, evaluation order is often opposite to expectations from strict languages.
For example, in `let wrap = x: { wrapped = x; }; in wrap (1 + 2)`, the function body produces a result (`{ wrapped = ...; }`) *before* evaluating `x`.
## Infinite recursion and stack overflow
During evaluation, two types of errors can occur when expressions reference themselves or call functions too deeply:
### Infinite recursion
This error occurs when a value depends on itself through a cycle, making it impossible to compute.
```nix
let x = x; in x
=> error: infinite recursion encountered
```
Infinite recursion happens at the value level when evaluating an expression requires evaluating the same expression again.
Despite the name, infinite recursion is cheap to compute and does not involve a stack overflow.
The cycle is finite and fairly easy to detect.
### Stack overflow
This error occurs when the call depth exceeds the maximum allowed limit.
```nix
let f = x: f (x + 1);
in f 0
=> error: stack overflow; max-call-depth exceeded
```
Stack overflow happens when too many function calls are nested without returning.
The maximum call depth is controlled by the [`max-call-depth` setting](@docroot@/command-ref/conf-file.md#conf-max-call-depth).

## Equality
- [Attribute sets][attribute set] are compared first by attribute names and then by items until a difference is found.
- [Lists][list] are compared first by length and then by items until a difference is found.
- Comparison of distinct [functions][function] returns `false`, but identical functions may be subject to [value identity optimization](#value-identity-optimization).
- [Attribute sets][attribute set] and [lists][list] are compared recursively, and therefore are fully evaluated.
- Comparison of [functions][function] always returns `false`.
- Numbers are type-compatible, see [arithmetic] operators.
- Floating point numbers only differ up to a limited precision.
The `==` operator is [strict](@docroot@/language/evaluation.md#strictness) in both arguments; when comparing composite types ([attribute sets][attribute set] and [lists][list]), it is partially strict in their contained values: they are evaluated until a difference is found. <!-- this is woefully underspecified, affecting which expressions evaluate correctly; not just "ordering" or error messages. -->
### Value identity optimization
Nix performs equality comparisons of nested values by pointer equality or more abstractly, _identity_.
Nix semantics ideally do not assign a unique identity to values as they are created, but equality is an exception to this rule.
The disputable benefit of this is that it is more efficient, and it allows cyclical structures to be compared, e.g. `let x = { x = x; }; in x == x` evaluates to `true`.
However, as a consequence, it makes a function equal to itself when the comparison is made in a list or attribute set, in contradiction to a simple direct comparison.

> => true

[Logical disjunction]: #logical-disjunction
### Precedence and disjunctive normal form
The precedence of `&&` and `||` aligns with disjunctive normal form.
Without parentheses, an expression describes multiple "permissible situations" (connected by `||`), where each situation consists of multiple simultaneous conditions (connected by `&&`).
For example, `A || B && C || D && E` is parsed as `A || (B && C) || (D && E)`, describing three permissible situations: A holds, or both B and C hold, or both D and E hold.
## Logical implication
> **Syntax**
>
> *bool1* `->` *bool2*
Logical implication. Equivalent to `!`*bool1* `||` *bool2* (or `if` *bool1* `then` *bool2* `else true`).
This operator is [strict](@docroot@/language/evaluation.md#strictness) in *bool1*, but only evaluates *bool2* if *bool1* is `true`.

MIME type: `text/x-nix-cache-info`
## Format
Line-based key-value format:

Leading and trailing whitespace is trimmed from values.
Lines without a colon are ignored.
Unknown keys are silently ignored.
## Fields
### `StoreDir`
The Nix store directory path that this cache was built for (e.g., `/nix/store`).
If present, Nix verifies that this matches the client's store directory:

### `WantMassQuery`
`1` or `0`. Sets the default for [`want-mass-query`](@docroot@/store/types/http-binary-cache-store.md#store-http-binary-cache-store-want-mass-query).
### `Priority`
Integer. Sets the default for [`priority`](@docroot@/store/types/http-binary-cache-store.md#store-http-binary-cache-store-priority).
## Example

# Nix32 Encoding
Nix32 is Nix's variant of base-32 encoding, used for [store path digests](@docroot@/protocols/store-path.md), hash output via [`nix hash`](@docroot@/command-ref/new-cli/nix3-hash.md), and the [`outputHash`](@docroot@/language/advanced-attributes.md#adv-attr-outputHash) derivation attribute.
## Alphabet
The Nix32 alphabet consists of these 32 characters:
```
0 1 2 3 4 5 6 7 8 9 a b c d f g h i j k l m n p q r s v w x y z
```
The letters `e`, `o`, `u`, and `t` are omitted.
## Byte Order
Nix32 encoding processes the hash bytes from the end (last byte first), while base-16 encoding processes from the beginning (first byte first).
Consequently, the string sort order is determined primarily by the first bytes for base-16, and by the last bytes for Nix32.

# Release 2.33.0 (2025-12-09)
## New features
- New command `nix registry resolve` [#14595](https://github.com/NixOS/nix/pull/14595)
This command looks up a flake registry input name and returns the flakeref it resolves to.
For example, looking up Nixpkgs:
```
$ nix registry resolve nixpkgs
github:NixOS/nixpkgs/nixpkgs-unstable
```
Upstreamed from [Determinate Nix 3.14.0](https://github.com/DeterminateSystems/nix-src/pull/273).
- `nix flake clone` supports all input types [#14581](https://github.com/NixOS/nix/pull/14581)
`nix flake clone` now supports arbitrary input types. In particular, this allows you to clone tarball flakes, such as flakes on FlakeHub.
Upstreamed from [Determinate Nix 3.12.0](https://github.com/DeterminateSystems/nix-src/pull/229).
## Performance improvements
- Git fetcher computes `revCount`s using multiple threads [#14462](https://github.com/NixOS/nix/pull/14462)
When using Git repositories with a long history, calculating the `revCount` attribute can take a long time. Nix now computes `revCount` using multiple threads, making it much faster (e.g. 9.1s to 3.7s for Nixpkgs).
Note that if you don't need `revCount`, you can disable it altogether by setting the flake input attribute `shallow = true`.
Upstreamed from [Determinate Nix 3.12.2](https://github.com/DeterminateSystems/nix-src/pull/245).
- `builtins.stringLength` now runs in constant time [#14442](https://github.com/NixOS/nix/pull/14442)
The internal representation of strings has been replaced with a size-prefixed Pascal style string. Previously Nix stored strings as a NUL-terminated array of bytes, necessitating a linear scan to calculate the length.
- Uploads to `http://` and `https://` binary cache stores now run in constant memory [#14390](https://github.com/NixOS/nix/pull/14390)
Nix used to buffer the whole compressed NAR contents in memory. It now reads it in a streaming fashion.
- Channel URLs migrated to channels.nixos.org subdomain [#14517](https://github.com/NixOS/nix/issues/14517) [#14518](https://github.com/NixOS/nix/pull/14518)
Channel URLs have been updated from `https://nixos.org/channels/` to `https://channels.nixos.org/` throughout Nix. This subdomain provides better reliability with IPv6 support and improved CDN distribution. The old domain apex (`nixos.org/channels/`) currently redirects to the new location but may be deprecated in the future.
- Fix `download buffer is full; consider increasing the 'download-buffer-size' setting` warning [#11728](https://github.com/NixOS/nix/issues/11728) [#14614](https://github.com/NixOS/nix/pull/14614)
The underlying issue that led to [#11728](https://github.com/NixOS/nix/issues/11728) has been resolved by utilizing
[libcurl write pausing functionality](https://curl.se/libcurl/c/curl_easy_pause.html) to control backpressure when unpacking to slow destinations like the git-backed tarball cache. The default value of `download-buffer-size` is now 1 MiB and it's no longer recommended to increase it, since the root cause has been fixed.
This is expected to improve download performance on fast connections, since previously a single slow download consumer would stall the thread and prevent any other transfers from progressing.
Many thanks go out to the [Lix project](https://lix.systems/) for the [implementation](https://git.lix.systems/lix-project/lix/commit/4ae6fb5a8f0d456b8d2ba2aaca3712b4e49057fc) that served as inspiration for this change and for triaging libcurl [issues with pausing](https://github.com/curl/curl/issues/19334).
- Significantly improve tarball unpacking performance [#14689](https://github.com/NixOS/nix/pull/14689) [#14696](https://github.com/NixOS/nix/pull/14696) [#10683](https://github.com/NixOS/nix/issues/10683) [#11098](https://github.com/NixOS/nix/issues/11098)
Nix uses a content-addressed cache backed by libgit2 for deduplicating files fetched via `fetchTarball` and `github`, `tarball` flake inputs. Its usage has been significantly optimised to reduce the amount of I/O operations that are performed. For a typical nixpkgs source tarball this results in 200 times fewer system calls on Linux. In combination with libcurl pausing this alleviates performance regressions stemming from the tarball cache.
- Already valid derivations are no longer copied to the store [#14219](https://github.com/NixOS/nix/pull/14219)
This results in a modest speedup when using the Nix daemon.
- `nix nar ls` and `nix nar cat` are significantly faster and no longer buffer the whole NAR in memory [#14273](https://github.com/NixOS/nix/pull/14273) [#14732](https://github.com/NixOS/nix/pull/14732)
## S3 improvements
- Improved S3 binary cache support via HTTP [#11748](https://github.com/NixOS/nix/issues/11748) [#12403](https://github.com/NixOS/nix/issues/12403) [#12671](https://github.com/NixOS/nix/issues/12671) [#13084](https://github.com/NixOS/nix/issues/13084) [#13752](https://github.com/NixOS/nix/pull/13752) [#13823](https://github.com/NixOS/nix/pull/13823) [#14026](https://github.com/NixOS/nix/pull/14026) [#14120](https://github.com/NixOS/nix/pull/14120) [#14131](https://github.com/NixOS/nix/pull/14131) [#14135](https://github.com/NixOS/nix/pull/14135) [#14144](https://github.com/NixOS/nix/pull/14144) [#14170](https://github.com/NixOS/nix/pull/14170) [#14190](https://github.com/NixOS/nix/pull/14190) [#14198](https://github.com/NixOS/nix/pull/14198) [#14206](https://github.com/NixOS/nix/pull/14206) [#14209](https://github.com/NixOS/nix/pull/14209) [#14222](https://github.com/NixOS/nix/pull/14222) [#14223](https://github.com/NixOS/nix/pull/14223) [#14330](https://github.com/NixOS/nix/pull/14330) [#14333](https://github.com/NixOS/nix/pull/14333) [#14335](https://github.com/NixOS/nix/pull/14335) [#14336](https://github.com/NixOS/nix/pull/14336) [#14337](https://github.com/NixOS/nix/pull/14337) [#14350](https://github.com/NixOS/nix/pull/14350) [#14356](https://github.com/NixOS/nix/pull/14356) [#14357](https://github.com/NixOS/nix/pull/14357) [#14374](https://github.com/NixOS/nix/pull/14374) [#14375](https://github.com/NixOS/nix/pull/14375) [#14376](https://github.com/NixOS/nix/pull/14376) [#14377](https://github.com/NixOS/nix/pull/14377) [#14391](https://github.com/NixOS/nix/pull/14391) [#14393](https://github.com/NixOS/nix/pull/14393) [#14420](https://github.com/NixOS/nix/pull/14420) [#14421](https://github.com/NixOS/nix/pull/14421)
S3 binary cache operations now happen via HTTP, leveraging `libcurl`'s native AWS SigV4 authentication instead of the AWS C++ SDK, providing significant improvements:
- **Reduced memory usage**: Eliminates memory buffering issues that caused segfaults with large files
- **Fixed upload reliability**: Resolves AWS SDK chunking errors (`InvalidChunkSizeError`)
- **Lighter dependencies**: Uses lightweight `aws-crt-cpp` instead of full `aws-cpp-sdk`, reducing build complexity
The new implementation requires curl >= 7.75.0 and `aws-crt-cpp` for credential management.
All existing S3 URL formats and parameters remain supported, however the store settings for configuring multipart uploads have changed:
- **`multipart-upload`** (default: `false`): Enable multipart uploads for large files. When enabled, files exceeding the multipart threshold will be uploaded in multiple parts.
- **`multipart-threshold`** (default: `100 MiB`): Minimum file size for using multipart uploads. Files smaller than this will use regular PUT requests. Only takes effect when `multipart-upload` is enabled.
- **`multipart-chunk-size`** (default: `5 MiB`): Size of each part in multipart uploads. Must be at least 5 MiB (AWS S3 requirement). Larger chunk sizes reduce the number of requests but use more memory.
- **`buffer-size`**: Has been replaced by `multipart-chunk-size` and is now an alias to it.
Note that this change also means Nix now supports S3 binary cache stores even if built without `aws-crt-cpp`, but only for public buckets which do not require authentication.
- S3 URLs now support object versioning via `versionId` parameter [#13955](https://github.com/NixOS/nix/issues/13955) [#14274](https://github.com/NixOS/nix/pull/14274)
S3 URLs now support a `versionId` query parameter to fetch specific versions
of objects from S3 buckets with versioning enabled. This allows pinning to
exact object versions for reproducibility and protection against unexpected
changes:
```
s3://bucket/key?region=us-east-1&versionId=abc123def456
```
- S3 binary cache stores now support storage class configuration [#7015](https://github.com/NixOS/nix/issues/7015) [#14464](https://github.com/NixOS/nix/pull/14464)
S3 binary cache stores now support configuring the storage class for uploaded objects via the `storage-class` parameter. This allows users to optimize costs by selecting appropriate storage tiers based on access patterns.
Example usage:
```bash
# Use Glacier storage for long-term archival
nix copy --to 's3://my-bucket?storage-class=GLACIER' /nix/store/...
# Use Intelligent Tiering for automatic cost optimization
nix copy --to 's3://my-bucket?storage-class=INTELLIGENT_TIERING' /nix/store/...
```
The storage class applies to both regular uploads and multipart uploads. When not specified, objects use the bucket's default storage class.
See the [S3 storage classes documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html) for available storage classes and their characteristics.
## Store path info JSON format changes
The JSON format emitted by `nix path-info --json` has been updated to a new version with improved structure.
To maintain compatibility, `nix path-info --json` now requires a `--json-format` flag to specify the output format version.
Using `--json` without `--json-format` is deprecated and will become an error in a future release.
For now, it defaults to version 1 with a warning, for a smoother migration.
### Version 1 (`--json-format 1`)
This is the legacy format, preserved for backwards compatibility:
- String-based hash values (e.g., `"narHash": "sha256:FePFYIlM..."`)
- String-based content addresses (e.g., `"ca": "fixed:r:sha256:1abc..."`)
- Full store paths for map keys and references (e.g., `"/nix/store/abc...-foo"`)
- Now includes `"storeDir"` field at the top level
### Version 2 (`--json-format 2`)
The new structured format follows the [JSON guidelines](@docroot@/development/json-guideline.md) with the following changes:
- **Nested structure with top-level metadata**:
The output is now wrapped in an object with `version`, `storeDir`, and `info` fields:
```json
{
"version": 2,
"storeDir": "/nix/store",
"info": { ... }
}
```
The map from store path base names to store object info is nested under the `info` field.
- **Store path base names instead of full paths**:
Map keys and references use store path base names (e.g., `"abc...-foo"`) instead of full absolute store paths.
Combined with `storeDir`, the full path can be reconstructed.
- **Structured `ca` field**:
Content address is now a structured JSON object instead of a string:
- Old: `"ca": "fixed:r:sha256:1abc..."`
- New: `"ca": {"method": "nar", "hash": "sha256-ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0="}`
- Still `null` values for input-addressed store objects
The `hash` field uses the [SRI](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity) format like other hashes.
Additionally the following fields are added to both formats:
- **`version` field**:
All store path info JSON now includes `"version": <1|2>`. The `version` tracks breaking changes, and adding fields to outputted JSON is not a breaking change.
- **`storeDir` field**:
Top-level `"storeDir"` field contains the store directory path (e.g., `"/nix/store"`).
## Derivation JSON format changes
The derivation JSON format has been updated from version 3 to version 4:
- **Nested structure with top-level metadata**:
The output of `nix derivation show` is now wrapped in an object with `version` and `derivations` fields:
```json
{
"version": 4,
"derivations": { ... }
}
```
The map from derivation paths to derivation info is nested under the `derivations` field.
This matches the structure used for `nix path-info --json --json-format 2`, and likewise brings this command into compliance with the JSON guidelines.
- **Restructured inputs**:
Inputs are now nested under an `inputs` object:
- Old: `"inputSrcs": [...], "inputDrvs": {...}`
- New: `"inputs": {"srcs": [...], "drvs": {...}}`
- **Consistent content addresses**:
Fixed content-addressed outputs now use structured JSON format.
This is the same format as `ca` in store path info (after the new version).
Version 3 and earlier formats are *not* accepted when reading.
**Affected command**: `nix derivation`, namely its `show` and `add` sub-commands.
## Miscellaneous changes
- Git fetcher: Restore progress indication [#14487](https://github.com/NixOS/nix/pull/14487)
Nix used to feel "stuck" while it was cloning large repositories. Nix now shows Git's native progress indicator while fetching.
Upstreamed from [Determinate Nix 3.13.0](https://github.com/DeterminateSystems/nix-src/pull/250).
- Interrupting REPL commands works more than once [#13481](https://github.com/NixOS/nix/issues/13481)
Previously, this only worked once per REPL session; further attempts would be ignored.
This issue is now fixed, so REPL commands such as `:b` or `:p` can be canceled consistently.
This is a cherry-pick of the change from the [Lix project](https://gerrit.lix.systems/c/lix/+/1097).
- NAR unpacking code has been rewritten to make use of dirfd-based `openat` and `openat2` system calls when available [#14597](https://github.com/NixOS/nix/pull/14597)
- Dynamic size unit rendering [#14423](https://github.com/NixOS/nix/pull/14423) [#14364](https://github.com/NixOS/nix/pull/14364)
Various commands and the progress bar now use dynamically determined size units instead
of always using `MiB`. For example, the progress bar now reports download status like:
```
[1/196/197 copied (773.7 MiB/2.1 GiB), 172.4/421.5 MiB DL]
```
Instead of:
```
[1/196/197 copied (773.7/2147.3 MiB), 172.4/421.5 MiB DL]
```
