Latest developments

9 November 2026Claude Code stores approved commands containing passwords in settings.local.json

If you choose "Yes, and don't ask again" in Claude Code, the tool saves the command verbatim in .claude/settings.local.json, including passwords or API keys. Apiiro found real secrets in 1,122 of 104,185 public copies on GitHub, including 379 database passwords. Keep the file out of git, use variables for secrets, and replace any keys that have already leaked. source

November 2 2026Message threads (beta) fall outside Zero Data Retention

With message threads in the Claude API, Anthropic stores the conversation, the system prompt and the tools on the server, encrypted in memory and not on disk, until up to one hour after the last use. The feature does not qualify for Zero Data Retention; your other ZDR agreements still apply. If you work with personal data under ZDR, only enable threads if your DPIA covers it. source

26 October 2026Swedish government office blocks the browser version on work computers

From 26 October, the Swedish government office blocks ChatGPT and Claude on work computers because there is no formal contract and there are information security risks; Microsoft Copilot remains permitted. Business use therefore requires a contract with data processing terms. source
