+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.

+
+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 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).

-
-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.

-In this form, the attribute set between the `{` `}` is recursive.
-
-One of the attributes must have the special name `body`,
-which is the result of the expression.

-Example:
-
-```nix
-let {
-  foo = bar;
-  bar = "baz";
-  body = foo;
-}
-```
-
-This evaluates to "baz".

 ## Inheriting attributes
 
 When defining an [attribute set](./types.md#type-attrs) or in a [let-expression](#let-expressions) it is often convenient to copy variables from the surrounding lexical scope (e.g., when you want to propagate attributes).

-# Nix Cache Info Format
-
-The `nix-cache-info` file is a metadata file at the root of a [binary cache](@docroot@/package-management/binary-cache-substituter.md) (e.g., `https://cache.example.com/nix-cache-info`).
-
-MIME type: `text/x-nix-cache-info`
-
-## Format
-
-Line-based key-value format:
-
-```
-Key: value
-```
-
-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:
-
-```
-error: binary cache 'https://example.com' is for Nix stores with prefix '/nix/store', not '/home/user/nix/store'
-```
-
-### `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
-
-```
-StoreDir: /nix/store
-WantMassQuery: 1
-Priority: 30
-```
-
-## Caching Behavior
-
-Nix caches `nix-cache-info` in the [cache directory](@docroot@/command-ref/env-common.md#env-NIX_CACHE_HOME) with a 7-day TTL.

-# 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.

-
-## 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 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]
-  ```
