 ### Added
 
-- **Performance insights.** Track how fast your site loads with Core Web Vitals (page load speed, layout shifts, responsiveness). Turn it on in Site Settings → Data & Privacy to see a performance widget on your dashboard.
+- **App Switcher in User Menu.** Click your profile in the top right and you'll now see a "Ciphera Apps" section. Expand it to quickly jump between Pulse, Drop (file sharing), and your Ciphera Account settings. This makes it easier to discover and navigate between Ciphera products without signing in again.
+- **Faster billing page loading.** Your subscription details now load much quicker when you visit the billing page. Previously, several requests to our payment provider were made one after another, which could add 1-2 seconds to the page load. Now these happen simultaneously, cutting the wait time significantly. If any request takes too long, we gracefully continue so you always see your billing information without frustrating delays.
+- **Faster funnel analysis for multi-step conversions.** We've significantly improved how conversion funnels are calculated. Instead of scanning your data multiple times for each step in a funnel, we now do it in a single efficient pass. This means complex funnels with multiple steps load almost instantly instead of taking seconds—or even timing out. We've also added a reasonable limit of 5 steps per funnel to ensure optimal performance.
+- **More reliable database connections under heavy load.** We've optimized how Pulse manages its database connections to handle much higher traffic without issues. By increasing the connection pool size and improving how connections are reused, your dashboard stays responsive even when thousands of users are viewing analytics simultaneously. We also added better monitoring so we can detect and address connection issues before they affect you.
+- **Better support for growing teams and traffic.** We've added infrastructure improvements that allow Pulse to run smoothly across multiple servers. When you scale up to handle more traffic, our background processes—like daily analytics calculations and data cleanup—will coordinate automatically so they don't conflict with each other. This ensures reliable performance as your team and data grow.
+- **Smarter protection for heavy dashboard operations.** We've implemented a new tiered rate limiting system that treats complex dashboard queries differently from simple requests. Expensive operations—like loading your full dashboard with all its charts and data—now have their own dedicated limits to prevent anyone from accidentally overwhelming the system with too many rapid refreshes. This keeps everything running smoothly for everyone, especially during busy periods.
+- **Smarter caching for faster dashboard loading.** We've added intelligent caching headers to our API responses, so your browser can remember recently loaded data and show it instantly when you navigate between pages. This works alongside our existing server-side caching to make your dashboard feel even more responsive—especially when switching between different date ranges or sections.
+- **More flexible uptime monitoring.** We've made our uptime checker more adaptable to different needs. Instead of a fixed limit on how many websites we can check simultaneously, you can now configure this based on your requirements. This means faster uptime checks for busy sites with many monitors, while keeping things efficient for smaller setups.
+- **Smarter data cleanup for better performance.** We've improved how old analytics data is cleaned up to keep everything running smoothly. Instead of deleting large amounts of data all at once—which could slow things down—we now remove old data in small, efficient batches. This ensures your dashboard stays fast and responsive even as we clean up months of historical data behind the scenes.
+- **Faster analytics processing for all sites.** We've upgraded how your daily analytics are calculated behind the scenes. Instead of processing sites one by one, we now analyze multiple sites simultaneously using a smart parallel system. This means your daily stats—like visitor counts and page views—are updated more quickly and consistently, even as we handle data from thousands of websites.
+- **Lighter dashboard data transfers.** Your dashboard now loads data in smaller, focused pieces instead of one massive bundle. This means faster loading times—especially on slower connections—and your analytics appear section by section as they become ready, rather than making you wait for everything at once.
+- **Smarter data fetching.** Your dashboard now automatically prevents duplicate requests when multiple components ask for the same data at the same time. It also briefly caches recent responses, so switching between pages feels instant while still keeping everything up to date. This reduces server load and makes the app feel snappier.
+- **Smarter dashboard updates.** Your dashboard now knows when you're actively viewing it versus when it's in the background. When you switch to another tab, we intelligently slow down data refreshes to save resources, then instantly catch up when you return. This keeps your analytics current without putting unnecessary load on the system.
+- **Instant real-time visitor counts.** Your dashboard's "current visitors" counter now updates lightning-fast using an optimized tracking system. Instead of scanning your entire database, we maintain a live session index that shows active visitors in milliseconds—even when thousands of people are browsing your sites simultaneously.
+- **Faster event tracking.** Your analytics data is now captured instantly without slowing down your website. We've switched to asynchronous processing that collects events in batches of 100, so your visitors' page views and interactions are recorded with zero impact on their browsing experience, even during traffic spikes.
+- **Faster dashboard loading.** Your site analytics now load almost instantly, even during busy periods. Behind the scenes, we've added intelligent caching that remembers your dashboard data for 30 seconds and refreshes it automatically in the background. Real-time visitor counts are updated every 5 seconds so you always see current activity without waiting.
+- **Better data management for long-term performance.** We've restructured how your analytics data is stored so the app stays fast even as you collect months of data. Old data is now automatically organized by month and cleaned up efficiently based on your retention settings, keeping everything running smoothly no matter how much traffic you get.
+- **Smarter database indexing.** We've optimized how your analytics data is indexed, making common queries—like loading your dashboard or filtering by date—significantly faster. This also reduces storage overhead, keeping the app lean as your data grows.
+- **Faster dashboard statistics.** Loading stats for any date range is now much quicker. Instead of recalculating from scratch every time, we use pre-computed daily summaries so your analytics appear instantly, even for months of data.
+- **Performance insights. Track how fast your site loads with Core Web Vitals (page load speed, layout shifts, responsiveness). Turn it on in Site Settings → Data & Privacy to see a performance widget on your dashboard.
 - **Goals & Events.** Define custom goals (e.g. signup, purchase) and track them with `pulse.track()` in your snippet. Counts appear on your dashboard once you add goals in Site Settings → Goals & Events.
 - **2FA recovery codes backup.** When you enable 2FA, you receive recovery codes. You can now regenerate new codes (with password confirmation) from Settings and download them as a `.txt` file. Regenerating invalidates all existing codes.

 - **Sign in after inactivity.** Clicking "Sign in" after a period of inactivity no longer does nothing. Previously, stale refresh cookies caused the middleware to redirect away from the login page; now only a valid access token triggers that redirect, so you can complete OAuth sign-in when your session has expired.
 - **Frequent re-login.** You no longer have to sign in multiple times a day. When the access token expires after 15 minutes of inactivity, the app now automatically refreshes it using your refresh token on the next page load, so you stay logged in for up to 30 days.
 - **2FA disable now requires password confirmation.** Disabling 2FA sends the derived password to the backend for verification. This prevents an attacker with a hijacked session from stripping 2FA.
+- **More accurate visitor tracking.** We fixed rare edge cases where visitor counts could be slightly off during busy traffic spikes. Previously, the timestamp-based session ID generation could occasionally create overlapping identifiers. Every visitor now gets a truly unique UUID that never overlaps with others, ensuring your analytics are always precise.
