Good morning, it's Friday, October 30th, 2026.
The big takeaway today is trust in the compression pipeline. Most of the merged work doesn't add features — it stops the system from silently doing the wrong thing with your data, your cache, or your token counts.
First, protecting what should never be compressed. One fix, in pull request 44-94, closes a bypass where batched small messages skipped role and mutability guards, meaning system and protected messages could be compressed when grouped. A related fix in 44-93 stops subscription traffic from writing learning…
Second, counting costs and time correctly. The highest-impact change here is pull request 44-41, which prices PDF document blocks by page count rather than as base-64 text. Before, a one-megabyte PDF could count as more than nine hundred thousand tokens, inflating usage and fake savings; now it's closer to fifteen…
Finally, over in Agent Reach, search got more resilient. Pull request 8-80 adds dispatcher-level fallback to public web search when site backends fail transiently, and paired requests 8-77 and 8-82 add a browser user agent to avoid Cloudflare blocking. Setup paper cuts also got attention — clearer login hints,…
