New: Log an adjusted dose. Tap "Log Entry" to record the actual amount taken, which can differ from your saved protocol dose. Adjusted entries are highlighted in your history so you can track any deviations from your protocol. Fixed: Calendar now correctly displays today's doses in all US timezones, previously rolled over to tomorrow after ~5-8pm local time. Fixed: Dose logs created in the evening now appear on the correct calendar day. Fixed: Protocols with two scheduled times now group and display correctly in the calendar. Fixed: Skipped and deferred log entries now show their correct status in protocol history instead of displaying as a completed dose. Fixed: Protocol export now preserves all schedule times including second administration time. Improved: Protocol history now clearly distinguishes completed, skipped, and deferred entries.
