hmm does this need a lock version bump? a previous version of uv will fail to parse upload-time
.
I think a previous version will just ignore it. |
Yeah, as long as the field being missing on a version that knows about the field is fine, then this is fine. |
Yeah versions of I think the main "bad" thing that can happen is when multiple versions of |
Yeah confirmed old versions can read this (they just ignore it). It's only used in the PEP 751 export, so I think that's ok. |

What you probably have not anticipated are lock files checked into version control, where one developer uses slightly older and another slightly newer version of Then again, this pushes folks to upgrade, that it's a win? 😆 |
Maybe it's worth adding a note in the changelog whenever the lock file's version/revision is bumped, together with these kind of changes. |
@dimaqq we did consider that, see #13176 (comment) @Viicos can you share more about what you want to see in the changelog and how it would help? |
Thanks for answering @zanieb, in our case we have |
Alright. Maybe we can add a dedicated "Lockfile" section — I'm not sure. We really try to avoid any churn here though, so it should be rare. |
* Migrate from mypy to pyrefly * Bump uv to avoid lock file churn * See astral-sh/uv#13176 * Add py.typed to package root to signal it supports typing
Yeah, we also experienced the format inconsistency issues when working against a committed |

We expect most users to be able to upgrade without making changes. ##### Breaking changes - **Update `uv version` to display and update project versions ([#​12349](astral-sh/uv#12349 Previously, `uv version` displayed uv's version. Now, `uv version` will display or update the project's version. This interface was [heavily requested](astral-sh/uv#6298) and, after much consideration, we decided that transitioning the top-level command was the best option. Here's a brief example: ```console $ uv init example Initialized project `example` at `./example` $ cd example $ uv version example 0.1.0 $ uv version --bump major example 0.1.0 => 1.0.0 $ uv version --short 1.0.0 ``` If used outside of a project, uv will fallback to showing its own version still: ```console $ uv version warning: failed to read project: No `pyproject.toml` found in current directory or any parent directory running `uv self version` for compatibility with old `uv version` command. this fallback will be removed soon, pass `--preview` to make this an error. uv 0.7.0 (4433f41c9 2025-04-29) ``` As described in the warning, `--preview` can be used to error instead: ```console $ uv version --preview error: No `pyproject.toml` found in current directory or any parent directory ``` The previous functionality of `uv version` was moved to `uv self version`. - **Avoid fallback to subsequent indexes on authentication failure ([#​12805](astral-sh/uv#12805 When using the `first-index` strategy (the default), uv will stop searching indexes for a package once it is found on a single index. Previously, uv considered a package as "missing" from an index during authentication failures, such as an HTTP 401 or HTTP 403 (normally, missing packages are represented by an HTTP 404). This behavior was motivated by unusual responses from some package indexes, but reduces the safety of uv's index strategy when authentication fails. Now, uv will consider an authentication failure as a stop-point when searching for a package across indexes. The `index.ignore-error-codes` option can be used to recover the existing behavior, e.g.: ```toml [[tool.uv.index]] name = "pytorch" url = "https://download.pytorch.org/whl/cpu" ignore-error-codes = [401, 403] ``` Since PyTorch's indexes always return a HTTP 403 for missing packages, uv special-cases indexes on the `pytorch.org` domain to ignore that error code by default. - **Require the command in `uvx <name>` to be available in the Python environment ([#​11603](astral-sh/uv#11603 Previously, `uvx` would attempt to execute a command even if it was not provided by a Python package. For example, if we presume `foo` is an empty Python package which provides no command, `uvx foo` would invoke the `foo` command on the `PATH` (if present). Now, uv will error early if the `foo` executable is not provided by the requested Python package. This check is not enforced when `--from` is used, so patterns like `uvx --from foo bash -c "..."` are still valid. uv also still allows `uvx foo` where the `foo` executable is provided by a dependency of `foo` instead of `foo` itself, as this is fairly common for packages which depend on a dedicated package for their command-line interface. - **Use index URL instead of package URL for keyring credential lookups ([#​12651](astral-sh/uv#12651 When determining credentials for querying a package URL, uv previously sent the full URL to the `keyring` command. However, some keyring plugins expect to receive the *index URL* (which is usually a parent of the package URL). Now, uv requests credentials for the index URL instead. This behavior matches `pip`. - **Remove `--version` from subcommands ([#​13108](astral-sh/uv#13108 Previously, uv allowed the `--version` flag on arbitrary subcommands, e.g., `uv run --version`. However, the `--version` flag is useful for other operations since uv is a package manager. Consequently, we've removed the `--version` flag from subcommands — it is only available as `uv --version`. - **Omit Python 3.7 downloads from managed versions ([#​13022](astral-sh/uv#13022 Python 3.7 is EOL and not formally supported by uv; however, Python 3.7 was previously available for download on a subset of platforms. - **Reject non-PEP 751 TOML files in install, compile, and export commands ([#​13120](astral-sh/uv#13120), [#​13119](astral-sh/uv#13119 Previously, uv treated arbitrary `.toml` files passed to commands (e.g., `uv pip install -r foo.toml` or `uv pip compile -o foo.toml`) as `requirements.txt`-formatted files. Now, uv will error instead. If using PEP 751 lockfiles, use the standardized format for custom names instead, e.g., `pylock.foo.toml`. - **Ignore arbitrary Python requests in version files ([#​12909](astral-sh/uv#12909 uv allows arbitrary strings to be used for Python version requests, in which they are treated as an executable name to search for in the `PATH`. However, using this form of request in `.python-version` files is non-standard and conflicts with `pyenv-virtualenv` which writes environment names to `.python-version` files. In this release, uv will now ignore requests that are arbitrary strings when found in `.python-version` files. - **Error on unknown dependency object specifiers ([12811](astral-sh/uv#12811 The `[dependency-groups]` entries can include "object specifiers", e.g. `set-phasers-to = ...` in: ```toml [dependency-groups] foo = ["pyparsing"] bar = [{set-phasers-to = "stun"}] ``` However, the only current spec-compliant object specifier is `include-group`. Previously, uv would ignore unknown object specifiers. Now, uv will error. - **Make `--frozen` and `--no-sources` conflicting options ([#​12671](astral-sh/uv#12671 Using `--no-sources` always requires a new resolution and `--frozen` will always fail when used with it. Now, this conflict is encoded in the CLI options for clarity. - **Treat empty `UV_PYTHON_INSTALL_DIR` and `UV_TOOL_DIR` as unset ([#​12907](astral-sh/uv#12907), [#​12905](astral-sh/uv#12905 Previously, these variables were treated as set to the current working directory when set to an empty string. Now, uv will ignore these variables when empty. This matches uv's behavior for other environment variables which configure directories. ##### Enhancements - Disallow mixing requirements across PyTorch indexes ([#​13179](astral-sh/uv#13179)) - Add optional managed Python archive download cache ([#​12175](astral-sh/uv#12175)) - Add `poetry-core` as a `uv init` build backend option ([#​12781](astral-sh/uv#12781)) - Show tag hints when failing to

Summary
In #12968, we added support for upload time to
uv.lock
, but stylized asupload_time
. The other keys inuv.lock
use kebab casing, as in common in Python formats, so this really should've beenupload-time
. I want to change it ASAP to minimize churn for users. Any users that already upgraded will of course experience churn in their files a second time. But if we don't change it now, we'll only increase the surface area of affected users.So, this PR uses
upload-time
instead, but continues readingupload_time
to make it non-breaking.
