CHANGELOG.md

@@ -4,6 +4,59 @@ All notable changes to Pulse (frontend and product) are documented in this file.
 
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and Pulse uses [Semantic Versioning](https://semver.org/spec/v2.0.0.html) with a **0.x.y** version scheme while in initial development. The leading `0` indicates that the public API and behaviour may change until we release **1.0.0**.
 
+## [Unreleased]
+
+## [0.8.0-alpha] - 2026-02-20
+
+### Added
+
+- **Renewal date and amount.** The dashboard and billing tab now show when your subscription renews and how much you'll be charged.
+- **Invoice preview when changing plans.** Before you switch plans, you can see exactly what your next invoice will be (including prorations).
+- **Pay now for open invoices.** Unpaid invoices show a clear "Pay now" button so you can settle them quickly.
+- **Enterprise contact.** The pricing page Enterprise plan now links to email us directly instead of checkout.
+- **Past due alert.** If your payment fails, a red banner appears with a link to update your payment method.
+- **Pageview usage bar.** Your billing card shows a color-coded bar so you can see at a glance how close you are to your limit (green, then amber, then red).
+
+### Changed
+
+- **Change plan flow.** Cleaner plan selector with Solo, Team, and Business options. Shows which plan you're on and a preview of your next invoice. If the preview can't be calculated, you'll see a friendly message instead of a blank screen.
+- **Billing tab layout.** Improved spacing, clearer headings, and better focus when using keyboard navigation.
+- **Pricing page layout.** Updated spacing and typography. Slider and billing toggle are more accessible.
+- **Billing Portal return.** After updating your payment method in Stripe's portal, you're taken back to the billing tab instead of the general settings page.
+
+### Fixed
+
+- **Theme toggle crash.** Fixed a crash that could occur when switching between light and dark mode on the pricing page and then opening organization settings.
+
+## [0.7.0-alpha] - 2026-02-17
+
+### Changed
+
+- **ciphera-ui consolidation.** Migrated shared components and utilities to @ciphera-net/ui (v0.0.57): SwissFlagIcon, CodeBlock, Spinner, format utilities (formatNumber, formatDuration, formatDate, getDateRange, formatUpdatedAgo, formatRelativeTime), and auth error utilities (getAuthErrorMessage, authMessageFromStatus, authMessageFromErrorType). Removed 6 local duplicate files (LoadingOverlay, SwissFlagIcon, CodeBlock, authErrors.ts, format.ts).
+- **Form card border radius.** Login, signup, invite accept, verify, reset-password, forgot-password, and organization create cards now use rounded-2xl to match design system.
+- **Hardcoded brand colors.** Uptime page chart uses CSS variable var(--color-brand-orange) instead of #FD5E0F.
+- **Selection styling.** Removed redundant selection:bg-brand-orange/20 from page wrappers; relies on ciphera-ui base styles.
+- **Inline spinners.** Dashboard widgets (TopReferrers, Locations, TechSpecs, Campaigns, ContentStats), notifications page, and OrganizationSettings now use Spinner from ciphera-ui.
+- **Footer layout.** Authenticated footer container aligned to max-w-6xl (matches site dashboard and page-container-app).
+
+### Removed
+
+- **Dead components.** LoadingOverlay.tsx (unused; all usage already from ciphera-ui).
+
+## [0.6.0-alpha] - 2026-02-13
+
+### Added
+
+- **Notification settings.** New Notifications tab in organization settings lets owners and admins toggle billing and uptime notification categories. Disabling a category stops new notifications of that type from being created.
+- **In-app notification center.** Bell icon in the header with dropdown of recent notifications. Uptime monitor status changes (down, degraded, recovered) create in-app notifications with links to the uptime page.
+- **Notifications UX improvements.** Bell dropdown links to "Manage settings" and "View all" notifications page. Unread count polls every 90 seconds. Full notifications page at /notifications with pagination.
+- **Notifications tab visibility.** Notifications tab in organization settings is hidden from members (owners and admins only).
+- **Audit log for notification settings.** Changes to notification preferences are recorded in the organization audit log.
+- **Payment failed notifications.** When Stripe sends `invoice.payment_failed`, owners and admins receive an in-app notification with a link to update payment method. Members do not see billing notifications.
+- **Pageview limit notifications.** Owners and admins are notified when usage reaches 80%, 90%, or 100% of the plan limit (checked every 6 hours).
+- **Trial ending soon.** When a trial ends within 7 days, owners and admins receive a notification. Triggered by Stripe webhooks and a periodic checker.
+- **Subscription canceled.** When a subscription is canceled, owners and admins are notified with a link to billing.
