Release Notes - v0.8.5.2

Release Date: February 6, 2026 Type: Bug Fix Release

Summary

This release focuses on fixing critical alpha testing bugs related to chat persistence, date formatting, and calendar integration. Also includes model/database alignment fixes for timezone-aware datetimes.

Bug Fixes

Critical Fixes

#787 - Conversation not appearing in sidebar - Fixed cross-user session bleed caused by localStorage session persistence across logout. Now properly clears user-specific localStorage on logout.
#788 - Invalid Date display - Fixed JavaScript Date parsing by replacing +00:00 with Z suffix in ISO date strings. PostgreSQL timestamptz returns +00:00 format which JavaScript Date() doesn’t parse correctly.
#789 - Calendar false positive - Fixed Piper claiming “No meetings - great day for deep work!” when no calendar is connected. Now distinguishes “not connected” from “connected with no events” and stays silent when not connected.

Additional Fixes

Timezone import fix - Added missing timezone import to intent_service.py
DateTime model alignment - Added timezone=True to all DateTime columns in models.py to match database schema after timestamptz migration
Test fixes - Updated test_file_repository_migration.py to use timezone-aware datetimes

Features

History Sidebar Differentiation (#786)

The History sidebar now uses monthly grouping (January, February, etc.) instead of the same Today/Yesterday/This Week grouping as the Conversation List. Search functionality has been wired up to filter conversations by title.

Issues Closed

#786 - GLUE-HISTORY-DIFF: Differentiate History sidebar from Conversation list
#787 - Conversation not appearing in sidebar after first chat
#788 - Invalid Date shown for new conversations
#789 - Piper claims “no meetings” without calendar connected

Known Issues

#766 - GLUE-MAINPROJ: “Is that your main project?” question repeats
#790 - MVP: Trust-gated calendar integration behavior (enhancement for future release)
