[Unreleased]

Added

• Financial Year: Income tab zeigt neu Revenue Accounts (Typ «Einnahmequelle») statt YearlyIncome-Einträge — Monatsgehalt × Monate = Jahreseinkommen; Toggle-Button pro Konto für 12 oder 13 Monatslöhne; Gesamtjahreseinkommen-Summe am Tab-Ende
• Account-Model: salary_months Feld (IntegerField, default 12, choices 12/13, Migration 0021); patchAccount() in ApiService
• Financial Year: Summary-Cards überarbeitet — (1) Jahreseinkommen aus Revenue Accounts, (2) Fixkosten/Monat × 12 = Jahresbetrag aus /budgets, (3) tatsächliche Ausgaben des gewählten Jahres aus /expenses (ersetzt «Verfügbar»)
• Financial Year: Haushalt-Finanzjahr erstellbar — Modal «Neues Jahr starten» zeigt Radio-Buttons «Persönlich» / Haushalt-Name wenn User aktive Haushaltsmitgliedschaft hat; Backend akzeptiert optionales household_id bei POST /api/financial-years/
• Financial Year: Haushalt-Modus Einnahmen-Tab zeigt Revenue Accounts aller aktiven Haushaltsmitglieder (neuer Endpoint GET /api/households/<pk>/revenue-accounts/); Partner-Accounts mit E-Mail-Hinweis
• household_id in FinancialYear-Serializer-Response
• Haushalt Einladungsflow für nicht-registrierte Benutzer: PendingHouseholdInvite Model (Migration 0022) speichert E-Mail ohne User-FK; nach Registrierung wird HouseholdMembership automatisch angelegt und PendingHouseholdInvite gelöscht
• Einladungs-E-Mail via household_invite Template (HTML + Plaintext) mit variablem CTA-Label; bestehende User erhalten «Einladung annehmen» → /financial-year, neue User «Konto erstellen & beitreten» → /register
• Frontend zeigt ausstehende Einladungen an nicht-registrierte Adressen mit Badge «Nicht registriert» in der Haushaltsliste
• FRONTEND_URL Setting (default http://localhost:4200; Prod: https://www.armarium.ch in .env)
• ProfileSerializer: get_email() gibt user.email zurück wenn Profile-Email leer — verhindert dass myMembership() für neue User keine Treffer findet

Fixed

• Dashboard: totalExpenses() filterte nicht nach ausgewähltem Jahr — alle Ausgaben wurden summiert
• Dashboard: totalIncome() und totalFixedCosts() lasen aus FinancialYear statt aus Revenue Accounts / /budgets — inkonsistent mit Dateneingabe-Workflow des Users
• Financial Year: updateIncome() und updateBudgetItem() verwendeten PUT statt PATCH → 405 Method Not Allowed
• Financial Year: reloadCurrentYear() löste NG0100 ExpressionChangedAfterItHasBeenCheckedError aus — Signal-Updates in setTimeout() verschoben
• Financial Year: PATCH /incomes/<id>/ und /budget-items/<id>/ gaben 403 zurück wenn is_active=False auf FinancialYear — is_active-Check aus 5 Backend-Views entfernt
• Backend: Profile.email_verified und verwandte Felder existierten in DB aber nicht im Model → IntegrityError beim Login neuer User; Felder ins Model aufgenommen (Migration 0023, fake-applied); DB-Defaults via ALTER COLUMN ... SET DEFAULT gesetzt

Added

• Navbar: avatar dropdown and notification panel converted from Flowbite JS (data-dropdown-toggle) to Angular state management (avatarDropdownOpen signal + backdrop <div> for outside-click close); eliminates Flowbite JS runtime dependency
• Navbar: sun/moon/bell icons replaced with Flowbite outline variants; logout entry in avatar dropdown now shows arrow-right-to-bracket icon
• Sidebar: navigation icons restored to fill style (fill="currentColor" viewBox="0 0 20 20") for consistency with pre-migration appearance; Settings link added to mobile drawer after Profile link
• Dashboard: greeting H1 changed to font-light (weight 300)

• Mobile — form grids: grid-cols-2 changed to grid-cols-1 sm:grid-cols-2 in expense modals and profile form
• Mobile — budget entries: min-w-0 flex-1 and truncate on name/account spans prevent overflow on narrow screens
• Mobile — calendar: day cells min-h-[48px] sm:min-h-[64px], day detail drawer w-full sm:w-80
• Mobile — dashboard: KPI card padding p-3 sm:p-5, KPI values text-xl sm:text-2xl
• Mobile — login: OTP digit inputs h-10 w-10 sm:h-12 sm:w-12; backup code field placeholder removed (hint text above suffices)
• Mobile — settings: recovery email row flex-col sm:flex-row so button stacks below input on narrow screens
• Search: placeholder text styled placeholder-gray-400 (was unstyled)
• Typography: Roboto font self-hosted via @fontsource/roboto (300/400/500/700 weights) — no Google Fonts CDN, DSGVO/nDSG compliant; replaces Inter which was defined in the theme but never actually loaded
• Typography: unified font-size system — page title H1 text-2xl (24px), card/section H2 headers text-base (16px), sidebar navigation text-sm (14px), savings rate display text-3xl (30px); applied across Dashboard, Budgets, Expenses, Calendar, Profile, Settings and Sidebar
• Profile: password change fields no longer show browser autofill suggestions (autocomplete="new-password"); show/hide eye icon added to both password fields

• ChangePasswordView: invalidates and blacklists all other active sessions on password change
• authInterceptor: sends X-Session-Key header on all internal API requests
• Auth: completeLogin() and storeTokens() accept optional session_key; logout() clears session key from both storages

• Profile page: 2FA and Danger Zone sections removed and moved to new Settings page
• Authenticator app recommendation updated to: Proton Pass, Aegis (Android), Raivo OTP (iOS)
• Calendar: holidays and school holidays now shown in the current app language; reloaded automatically on language change via translate.onLangChange subscription
• Calendar: OpenHolidays API requests include languageIsoCode parameter; cache key includes language
• Calendar: today's date shown as violet ring/outline only (not filled) to prevent white-on-white hover text
• Notifications: "Mark as read" checkmark button per notification (replaces X icon)
• Notifications: "Mark all as read" button in panel header
• i18n: nav.mark_read, nav.mark_all_read keys (DE/FR/IT/EN)

• Login: authentication changed from username-based to email-based; password manager only needs email + password
• Mobile sidebar drawer: Notifications, Dark/Light toggle, Profile link and Logout moved from navbar into the sidebar so all user actions are accessible via the hamburger menu

Security

• Password Reset invalidiert alle aktiven Sessions des Nutzers (analog zu ChangePasswordView)
• Email-Verify-Token: SHA-256-Hash statt Klartext in DB; Ablaufzeit 24h
• VerifyEmailView + PasswordResetConfirmView mit AuthThrottle (5/min) gesichert

Fixed

• Security: TwoFactorRecoverConfirmView now verifies temp_token (password proof) before accepting a recovery code — previously anyone with a valid recovery code could bypass authentication entirely
• Security: ProfileView.delete now requires password verification (check_password) before deletion; returns 403 on failure
• Backend: URL conflict — api/notifications/ was mapped to both NotificationsView and NotificationPrefsView; prefs endpoint moved to api/notifications/prefs/
• Backend: fpdf2 export — em/en dash characters (—, –) caused FPDFUnicodeEncodingException with Helvetica (Latin-1 only); fixed with safe() helper using encode('latin-1', errors='replace') and replaced placeholder dashes with ASCII -
• Backend: migration 0017 (finance_profile.notif_deadlines etc.) was not applied on server restart, causing 500 on login; now documented that python manage.py migrate must be run after deployment
• Auth: LangSwitcher — [class.dark:text-violet-400] Angular binding error caused by Tailwind dark-mode colon in class name; fixed by using itemClass() method with [class] binding
• Auth: LangSwitcher — current signal initialized before langService was available; fixed by setting default 'de' and calling this.current.set(langService.current) in constructor body
• Dashboard: bar chart right padding increased so December bars are no longer clipped at the container edge

• i18n: nav.dark_mode, nav.light_mode keys for sidebar mobile theme toggle (DE/FR/IT/EN)
• i18n: auth.username_hint key for register page (DE/FR/IT/EN)
• Mobile navbar: right-side icons (notifications, theme toggle, avatar) caused the navbar to wrap to a second line on narrow screens, pushing page content below the fixed offset; icons are now hidden on mobile and integrated into the sidebar drawer
• Mobile notification panel: was full-width and flush against the top of the screen; now has left-4/right-4 margins, top-20 offset and rounded-xl corners
• Auth: new EmailAuthBackend performs case-insensitive email lookup so login works regardless of capitalisation
• Login/Register: placeholder texts removed from all username and password fields

---

[1.0.1] - 2026-04-14

Fixed

• Production deployment: replaced hardcoded http://127.0.0.1:8000 with relative paths (/api, /api/auth) in ApiService and AuthService so the frontend works on any server
• Production deployment: avatar image URLs in profile.ts and navbar.ts now use the relative path returned by the backend instead of prepending http://127.0.0.1:8000
• Sidebar: Budgets and Accounts submenus not expanding on mobile — replaced Flowbite data-collapse-toggle with Angular signal-based state (budgetsOpen, accountsOpen in SidebarService)

Added

• nginx.conf: reverse proxy config — serves Angular static build, proxies /api/ to Gunicorn on port 8000, serves /media/ as static files

---
