What's Changed since v2.0.0

v3.0.0 — Tool Consolidation & Safety

Breaking: Consolidated 55 tools down to 20 (~64% reduction, ~11,000 tokens saved per turn) using the STRAP action-parameter pattern.

MCP safety annotations on all 20 tools (readOnlyHint, destructiveHint, idempotentHint)
- 6 read-only tools auto-approved by Claude Code
- 2 destructive tools prompt for confirmation
send-email safety controls: dryRun preview, session rate limiting (OUTLOOK_MAX_EMAILS_PER_SESSION), recipient allowlist (OUTLOOK_ALLOWED_RECIPIENTS)
New update-email tool — unified mark-read, flag, unflag, complete
New utils/safety.js — shared rate limiter, allowlist checker, dry-run formatter

v3.1.0 — 12 Bug Fixes + 25 How-To Guides

Fixed callGraphAPI parameter order in 3 modules (24 API calls had method/path swapped)
Fixed auth server scope desync — now imports from central config.js
Fixed search-emails silent failure on personal accounts — progressive fallback with user warning
Fixed double URL encoding in 12 Graph API calls across 6 files
Fixed search-people, manage-contact, manage-rules, create-event, export, apply-category, access-shared-mailbox bugs
25 how-to guides with 12 screenshots added to documentation
