Claude Code 2.1.77 speeds resume, patches bypass

ANNOUNCEMENT PRODUCT GITHUB PRODUCT HUNT

Anthropic’s Claude Code v2.1.77 is a substantial maintenance release: --resume on large, fork-heavy sessions is up to 45% faster with lower peak memory, and a critical PreToolUse hook path that could bypass deny rules is fixed. It also ships broad CLI reliability fixes across terminal, tmux, and IDE integrations plus stronger sandbox and runaway-task guardrails.

// ANALYSIS

This is the kind of “stability-first” update that actually compounds developer productivity over time.

–The PreToolUse allow/deny bypass fix is the headline for teams enforcing strict permission policies, especially in managed enterprise setups.
–Resume speed and memory improvements directly target one of the most painful workflows in long, agent-heavy coding sessions.
–The 5GB output cutoff for background bash tasks is a practical safety net against unattended disk blowups.
–The long list of tmux, iTerm2, VS Code, paste/input, and navigation fixes suggests Anthropic is prioritizing day-to-day CLI ergonomics, not just shipping shiny features.

Claude Code Fable 5 triggers billing warnings

Developer Daniel Avila flagged a potential issue in Anthropic's Claude Code CLI when selecting the newly released Claude Fable 5 model, noting that he received billing warnings despite Anthropic's promotion offering free access to the model until June 23, 2026. The issue likely stems from a conflict in how the CLI manages authentication, as the free promotional period is restricted to subscription plan logins (Pro, Max, Team, Enterprise) and does not apply if the tool detects a direct ANTHROPIC_API_KEY environment variable, which bills the user immediately.
