Updates ty from 0.0.75 to 0.0.84

Release notes

Sourced from ty's releases.

0.0.84

Release Notes

Released on 2026-09-24.

This release addresses GHSA-vxvm-j4xq-q7m4, a use-after-free vulnerability during incremental type checking that can result in arbitrary code execution when analyzing a specially crafted Python project. Users who run ty on untrusted code should upgrade to 0.0.84 or newer.

Bug fixes

• Fix stale diagnostics from the LSP server after toggling showSyntaxErrors (#28759)

LSP server

• Complete string keys from dictionary initializers (#28820)
• Support LSP requests against closed documents (#28595)
• Select projects for external files using import search paths (#28594)
• Use workspace editor settings for external files (#28639)

Performance

• Avoid repeated subtyping checks for materialized recursive protocols (#28774)
• Skip reading notebooks when discovering scripts (#28781)

Core type checking

• Avoid incorrect simplification of TypeIs materializations (#28817)
• Fix disjointness of generic class types (#28787)
• Fix staticmethod shadowing through generic receivers and unions (#28766)
• Infer callable signatures from bounded type variables (#28599)
• Infer constant membership in inline list and set literals (e.g. "foo" in ["foo"] is now inferred as Literal[True]) (#28676)
• Infer through optional generic containers in the legacy solver (#28791)
• Preserve call narrowing during cyclic inference (#28708)
• Preserve intersections of type guard return types (#28796)
• Use subtyping for constraint-set implication (#28657)

Configuration

• Disable invalid-legacy-positional-parameter by default (#28834)

Other changes

• Only consider reachable definitions when determining whether a condition should be exempted from redundant-condition(-strict) due to the condition being defined relative to sys.version_info, sys.platform, os.name or typing.TYPE_CHECKING (#28788)

Updates openapi-python-client from 0.29.0 to 0.29.1

Release notes

Sourced from openapi-python-client's releases.

0.29.1 (2026-08-30)

🚨Security

Arbitrary code generation vulnerability

Prior to this release, malicious OpenAPI documents could cause openapi-python-client to generate arbitrary code, which would then be executed by consumers of the generated client.

If you generate code from OpenAPI documents you don't control, you should upgrade to this release as soon as possible and validate any previously-generated code.

See the GitHub advisory for more details.

🚀 Features

• Update uv_build to 0.12 when using --meta=uv (#1473)

🐛 Fixes

• Apply PEP 639 for improved license metadata (#1459)
• update generated code to use StrEnum and -> Self (#1474)
• Remove trailing spaces in README example code (#1475)
• Stopped generating empty docstrings for models with no description

Fixed invalid Python identifiers when resolving naming conflicts

When two property or parameter names conflicted after conversion to snake_case (e.g. foo-bar and fooBar), the conflict-resolution path preserved delimiters like -, ., and spaces in the generated Python identifiers, producing invalid code which failed generation. Conflicting names now keep their original casing but have any characters which are invalid in Python identifiers stripped (e.g. foobar and fooBar).

Improve readability of error messages

Errors and warnings which include a snippet of your OpenAPI document now render that snippet as JSON, making them much easier to read.

📝Notes

Breaking changes for all custom templates

ALL custom templates are expected to break with this version as a result of the security fix.

1. The utils global has been renamed to strings
2. Most string values can no longer be rendered directly into templates, you must describe how the value is being used so it can be properly escaped using either a Python function or Jinja filter:
   1. strings.snake_case() / | snakecase (existing)
   2. strings.kebab_case() / | kebabcase (existing)
   3. strings.pascal_case() / | pascalcase (existing)
   4. python_identifier() (existing)
   5. class_name() (existing)
   6. strings.safe_for_docstring() / | safe_for_docstring for values which get injected into a """ docstring
   7. strings.in_f_string_literal() / | in_f_string_literal for values that go into f"" f-strings
   8. strings.in_double_quote_literal() / | in_double_quote_literal for values that go into non-f-string "" literals
   9. .as_unembedded_code() / | as_unembedded_code ONLY for PythonCode values—those that are intended to be Python code which is not embedded into any string/docstring. Examples include usages of .python_code, .get_type_string(), .get_instance_type_string(), .get_type_strings_in_union(). You should not assume these values are safe to put in docstrings, string literals, or f-string literals. Use the dedicated helpers for those.
