1.0.0rc1 (February 23, 2026)

We're ready! I'm thrilled to announce the first release candidate for Starlette 1.0.

Starlette was created in June 2018 by Tom Christie, and has been on ZeroVer for years. Today, it's downloaded almost 10 million times a day, serves as the foundation for FastAPI, and has inspired many other frameworks. In the age of AI, Starlette continues to play an important role as a dependency of the Python MCP SDK.

This release focuses on removing deprecated features that were marked for removal in 1.0.0, along with some last minute bug fixes. It's a release candidate, so we can gather feedback from the community before the final 1.0.0 release soon.

A huge thank you to all the contributors who have helped make Starlette what it is today. In particular, I'd like to recognize:

• Kim Christie - The original creator of Starlette, Uvicorn, and MkDocs, and the current maintainer of HTTPX. Kim's work helped lay the foundation for the modern async Python ecosystem.
• Adrian Garcia Badaracco - One of the smartest people I know, whom I have the pleasure of working with at Pydantic.
• Thomas Grainger - My async teacher, always ready to help with questions.
• Alex Grönholm - Another async mentor, always prompt to help with questions.
• Florimond Manca - Always present in the early days of both Starlette and Uvicorn, and helped a lot in the ecosystem.
• Amin Alaee - Contributed a lot with file-related PRs.
• Sebastián Ramírez - Maintains FastAPI upstream, and always in contact to help with upstream issues.
• Alex Oleshkevich - Helped a lot on templates and many discussions.

Dependency Update Review

Package: starlette 0.49.3 → 1.0.1
Semver risk: Major (0.x → 1.0)
Dependency type: Docs tooling only — transitive via sphinx-autobuild in [project.optional-dependencies.docs]; not a direct project dependency and not imported anywhere in source code
CI status: All critical checks passing (unit tests + cryptography on Python 3.9–3.13, postgres unit tests, SQLite migration tests, build wheel); plain unit test matrix runs still queued but expected to pass

Changelog Analysis

Sources consulted:

• Release notes in PR body (1.0.1, 1.0.0, 1.0.0rc1 sections from starlette releases)
• Commit range linked in PR body: 0.49.3...1.0.1

Breaking changes:

• 1.0.0rc1 removed deprecated features from the 0.x series — full list truncated in PR body, but has no impact here since starlette is not imported by this project's source

Security fixes: None noted in this range

Other notable changes:

• 1.0.0: Session access tracking in SessionMiddleware; fixes to websocket denial responses, FormParser, and MultiPartParser
• 1.0.1: Ignore malformed Host header when constructing request.url

Lockfile notes

The update also consolidates two previously distinct starlette pins (0.49.3 for Python 3.9, 0.52.1 for Python 3.10+) into a single 1.0.1 entry — praise: clean reduction of version-split complexity in the lock graph. The exclude-newer timestamp change (2026-03-26T... → 0001-01-01T...) is a uv compatibility format change for relative date handling (exclude-newer = "7 days" in pyproject.toml); the comment in the lockfile confirms this has no functional effect.

Compatibility Assessment

• Project uses starlette directly: No — zero imports in source; used only transitively by sphinx-autobuild
• Peer dependency changes: None
• Code changes required: No
• Prior failed attempts: No maintainer comments flagging prior issues

Recommendation

APPROVE — starlette is a docs-only transitive dependency; all critical CI suites pass; no code changes required.

How was this generated?

Reviewed the pull request diff checking for:

• Correctness: bugs, edge cases, undocumented behavior, resource leaks, hardcoded values
• Design: unnecessary complexity, naming, readability, comment accuracy, redundant state
• Architecture: duplicated concerns, minimal interfaces, composition over inheritance
• Testing: behavior-based assertions, mocks only at hard boundaries, accurate coverage
• Completeness: missing dependencies, unupdated usages, i18n, accessibility, security
• Principles: DRY (same reason to change), SRP, Rule of Three (no premature abstraction)
• Checked CI status and linked issue acceptance criteria
• For UI changes: inspected screenshots for layout, visual completeness, and consistency
