-* Append the preview number suffix to each filename: `-preview{N}` (where `{N}` is the preview number, e.g., `-preview2`).
+* Lowercase, hyphenated, descriptive names using whole words only.
+* Each word and number must be separated by a hyphen. Do not combine words or abbreviate them, and do not combine numbers with words.
+  - **Wrong**: `infer-pk-display-name-preview2.md` (`pk` is an abbreviation, and `preview2` combines a word with a number)

   **CRITICAL**: Every new file MUST include the preview suffix. This was a mistake
   in the initial automation — a file was created without the suffix and had to be
   corrected.

+### Rate-limiting middleware returns accurate `Retry-After` headers
+
+The <xref:System.Threading.RateLimiting.FixedWindowRateLimiter> now reports a <xref:System.Threading.RateLimiting.MetadataName.RetryAfter> metadata value that accurately reflects the next window boundary. Apps that propagate this metadata to the `Retry-After` response header in their <xref:Microsoft.AspNetCore.RateLimiting.RateLimiterOptions.OnRejected> callback now produce correct retry intervals automatically, with no code changes required.
+
+Additional fixes in `System.Threading.RateLimiting` resolve an issue where <xref:System.Threading.RateLimiting.TokenBucketRateLimiter> mishandled partial token refills during zero-permit acquisition, and improve the chained rate limiter returned by <xref:System.Threading.RateLimiting.RateLimiter.CreateChained*> to correctly forward idle-duration and replenishment behavior from its inner limiters.
+
+For an overview of the rate limiting middleware, see [Rate limiting middleware in ASP.NET Core](/aspnet/core/performance/rate-limit).
