yottacode v0.5.0: Hardened for Daily Engineering

October 14, 2026

yottacode v0.5.0 is out.

This release is a hardening release for people using yottacode on real repositories: longer sessions, more consequential edits, parallel work, CI workflows, and local-first tooling all received focused improvements.

What changed in v0.5.0

Deterministic deep research — /deep-research plans independent questions, runs researchers in parallel, verifies claims, and writes a cited report with explicit coverage and cost reporting.
Safer approvals and permissions — approval cards are clearer, chained commands and more tool families can save narrowly scoped rules, and policy matching is hardened across worktrees and edits.
More reliable edits — receipt-based and line-addressed hashline edits reduce stale-context failures and make large-file changes safer to apply.
Browser automation foundations — experimental browser tools use isolated profiles, explicit approvals, safer navigation boundaries, tab tracking, and human handoff for verification challenges.
Stronger document tooling — native xlsx/pptx paths and sandbox-aware docx/pdf helpers now cover more local document workflows, including structured PDF extraction and OCR fallbacks.
ACP and session improvements — model/session controls, replay, memory, recall, and context handling are more robust across long-running workflows.
Sandbox and runtime hardening — command execution, background jobs, credential handling, and subprocess lifecycle behavior received additional safeguards.
Homebrew distribution — stable releases are now available through the official yottadynamics/homebrew-yottacode tap for macOS Intel and Apple Silicon.

The release includes the cumulative work since v0.5.0-rc.2, including approval UX improvements, edit reliability, browser hardening, native web search, shell transcript logs, and the release packaging path.
