Breaking changes

• Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for more details and the new Default Rules page for a full listing of the enabled rules. Note that this is primarily an expansion, but 18 of the more opinionated pycodestyle (E) and pyflakes (F) rules have been removed from the default set: E401, E402, E701, E702, E703, E711, E712, E713, E714, E721, E731, E741, E742, E743, F403, F405, F406, and F722.

• Ruff can now format Python code blocks in Markdown files and will do this by default. See the documentation for more details.

• Ruff now supports ruff: ignore comments at the ends of lines, like noqa comments, or on the line preceding a diagnostic. For example, these both suppress an unused-import (F401) diagnostic:

  import math  # ruff: ignore[F401]
  ruff: ignore[F401]
  import os

• Fixes are now shown in check and format --check output:

  ❯ ruff format --check .
  unformatted: File would be reformatted
   --> try.md:1:1
    |
  1 | ```python
    - import   math
  2 + import math
  3 | ```
    |
  1 file would be reformatted

  This example also shows off the Markdown formatting.

• format --check now supports the same output formats as the linter, including the github and gitlab outputs for rendering annotations in CI:

  ❯ ruff format --check --output-format github .
  ::error title=ruff (unformatted),file=try.md,line=2,col=8,endLine=2,endColumn=10::try.md:2:8: unformatted: File would be reformatted

  See the CLI help or documentation for the full list of supported formats.

• The filename, location, end_location, fix.edits[].location, and fix.edits[].end_location fields in the JSON output format may now be null rather than defaulting to the empty string and row 1, column 1, respectively.

Pinning select makes the [tool.ruff.lint.isort] block below (lines 110-114) permanently dead config.

Ruff only applies [tool.ruff.lint.isort] settings when isort rules (I001/I002) are actually selected. They were not in Ruff 0.15's default set, and they are not in ["E4", "E7", "E9", "F"] either — so known-first-party = ["deadline", "openjd"] has never had an effect and, with the select set now explicitly pinned, never will on a future Ruff upgrade.

Before this change the block was only latently inert (a future default-set expansion could have activated it); now it is inert by construction. Worth resolving one way or the other so the config does not imply import-order enforcement that is not happening:

• add "I" to select if import sorting is intended to be enforced (note this will likely flag existing files), or
• drop the [tool.ruff.lint.isort] block.

Same situation applies to ignore = ["E501"] on line 108: E501 is not in E4/E7/E9/F, so the ignore is a no-op (line length is handled by black/line-length instead). Harmless, but similarly misleading.

This PR creates unnecessary churn across the repo and I'm not sure if its useful. Closing this PR for now.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
