Claude Code v2.1.176 Adds Conversation-Language Session Titles and footerLinksRegexes, Closes a Model-Allowlist Bypass

GitHub·medium signal

Released June 12, v2.1.176 generates session titles in the language of your conversation and adds a footerLinksRegexes setting for regex-matched clickable link badges in the footer row. It also caches awsCredentialExport Bedrock credentials until their actual Expiration instead of a fixed hour, and fixes an availableModels enforcement gap where alias picks could be redirected to a blocked model via ANTHROPIC_DEFAULT_*_MODEL env vars. /fast now refuses to toggle into a model outside the allowlist.
