The write-behind row's Python cell moves from "unreleased" to its released form: PyPI 0.25.0+, with the wheel check, as the matrix's other rows record it. The cell also names the writer bounds and the exit flush, and states that an async miss under the distributed lock writes synchronously even after a timed-out lock wait.

Checked against cachekit/decorators/write_behind.py and cachekit/decorators/wrapper.py in the 0.25.0 and 0.25.1 wheels. Matrix-only change, so no changelog fragment.

Summary by CodeRabbit

• Documentation
  • The reliability feature matrix now lists Python write-behind as released in PyPI 0.25.0 and later. It clarifies that write-behind is opt-in and isn’t enabled by any preset.
  • The documentation describes queue limits and notes that queued updates can exceed them in some cases. It also clarifies that some writes remain synchronous, queued writes may land after an invalidation, and clean interpreter exits allow up to 10 seconds to flush queued writes.

Walkthrough

The feature matrix now records Python write-behind as released in PyPI 0.25.0+. It documents writer limits, clean-exit flushing, and when an async miss remains synchronous.

Merge Risk: Low · up to afdcb

The release is mergeable, but the matrix should clarify the timed-out lock path to avoid misleading users about lock ownership.

Full details: Title check

Explanation

The title names the change accurately. The PR updates the write-behind row's Python cell in the SDK feature matrix from unreleased to released in cachekit-py 0.25.0. The title says write-behind ships in 0.25.0, which matches the raw summary and the description. It is concise and specific. The ticket reference LAB-10680 and the docs(matrix) prefix are acceptable and do not make the title vague.
