# Changelog
## [2.0.2] - 2025-11-24
### Fixed
- **Critical**: Fixed configuration parser to support both nested and flat JSON formats
- Now correctly transforms `{ "account": { "smtp": {...}, "imap": {...} } }` to flat structure
- Maintains backward compatibility with old flat format
- Location: `src/accountManager.ts:10-45`
### Performance
- **Critical Fix**: Resolved 60+ second timeout issue in email fetch operations
- Root cause: ImapFlow socket timeout during message iteration
- Solution: Optimized fetch strategy for unfiltered searches
- Fetch exact sequence range (last N messages) instead of search-then-fetch
- Direct sequence number access: `(mailbox.exists - limit + 1):mailbox.exists`
- Sort and limit results after fetching
- Performance improvement: 65+ seconds → <10 seconds for typical operations
- Added comprehensive timeout configuration:
- connectionTimeout: 15s
- greetingTimeout: 10s
- socketTimeout: 60s
- Operation timeout: 90s
- Location: `src/imapService.ts:12-254`

- Better error handling for configuration parsing
### Tested
