ProjectForge 9.0.0

⚠️ Major update - The classic Wicket user interface is gone: all pages run in projectforge-next, the only login is /next/login. This release sums up all 8.2 snapshot builds.

Before updating - Back up the database; its schema is migrated automatically at the first start.

ProjectForge 9.0: a new frontend, Wicket retired, all libraries up to date

ProjectForge 9.0 is a major update. The classic Wicket user interface was replaced by projectforge-next, a new frontend built with Next.js and React, and all libraries were brought up to date. It also brings a problem dashboard for operations, many new charts with key figures, robust interfaces to external systems, e-invoicing and an identity provider integration. The development builds leading up to it are listed in the changelog as 8.2 snapshots.

• New frontend projectforge-next: all pages migrated, including calendar, time sheets, order book, invoices, structure tree, access rights, monthly report, liquidity planning and administration. The classic Wicket module has been removed.
• Problem dashboard: log events are classified and aggregated into problems with a persistent status, with links into the log viewer, a JSON export for an AI-assisted analysis and prioritized error digest mails instead of one mail per error.
• Charts and key figures: order statistics with budget scenario, contribution margins, forecast, invoicing and net sum charts with a year-earlier comparison, invoicing quota and error figures in the system statistics.
• Robust interfaces: timeouts, connection pools, bounded sync threads and sync statistics for LDAP, identity provider, iCal, SMS, Sipgate and the gateway; an unreachable system fails fast instead of blocking, failing calendar subscriptions are retried with a growing interval.
• E-invoicing: XRechnung and ZUGFeRD export of outgoing invoices, PEPPOL validation, cancellation invoices and an e-invoice checker.
• Identity provider: synchronization of users, groups and passwords with Authentik or Keycloak (module projectforge-idp).
• Finance: recurring liquidity entries, DATEV import of incoming invoices, salary import, currency conversion with online exchange rates.
• Technology: Spring Boot 4.1, Spring 7, Hibernate 7.4, Hibernate Search 8.4, Tomcat 11, Kotlin 2.3, Next.js 16, React 19, TanStack Table.

Added

• projectforge-next
  • New frontend built with Next.js and React, with light and dark theme, compact top navigation and a quick access search for the menu.
  • Tables with column filters, pinning, reordering, saved layouts and filter favorites; multi selection and mass update for many entities.
  • Login with two-factor authentication and password reset under /next/login; stay logged in with one token per device.
• E-invoicing
  • XRechnung export and ZUGFeRD PDF with embedded XML, PEPPOL validation, invoice attachments embedded in the export.
  • Cancellation invoices and an e-invoice checker for ZUGFeRD/XRechnung files.
• Identity provider integration (module projectforge-idp): users, groups and passwords synchronized with Authentik or Keycloak, including WLAN password hashes.
• Problem dashboard
  • Log events are classified at the call site and aggregated in the database into problems with a persistent status.
  • Dashboard with tiles per subsystem, links into the log viewer, search of a problem's occurrences in the log files and an export as JSON for an AI-assisted analysis.
  • Prioritized error digest mails per audience instead of one mail per error; early digest for new security and data problems.
• Charts and key figures
  • Order statistics with its own filter, charts, data tables, budget scenario and warnings about lost budgets.
  • Contribution margins in the order book, forecast charts, net sum charts of outgoing invoices and invoice statistics with a year-earlier comparison.
  • Invoicing quota as a chart and in My statistics; error figures in the system statistics.
• Recurring series in the liquidity planning.
• Address import and export as vCard and from free text, with a diff view and a warning about duplicates.
• Incoming invoices imported from DATEV, with currency and exchange rates looked up online.
• Gateway for external data transfer with delta sync, CardDAV favorites and a public heartbeat.
• ICS import of team events with a diff preview.
• Changelog with news, search and highlighting under /next/changelog, also in German.

Improved

• All pages migrated to projectforge-next, among them calendar, time sheets, order book, outgoing and incoming invoices, structure tree, access rights, monthly report, liquidity planning, DATEV and salary import, HR planning, Gantt charts and administration; links and bookmarks of the classic pages lead to the new ones.
• Configurable customer groups and business units as filters for time sheets, invoices, projects and orders.
• Structure element picker with recently used entries and favorites; JIRA issue links in lists and forms.
• Server-side paging of order and invoice lists; deleted entries can be restored.
• Robust interfaces
  • Timeouts and shared connection pools for LDAP, identity provider, iCal, SMS, Sipgate and the gateway, configurable per interface.
  • An unreachable or too slow system fails fast with one warning instead of blocking; sync runs use bounded threads instead of a new thread per trigger.
  • Failing calendar subscriptions are retried with a growing interval and deactivated after 90 days.
  • Sync statistics with timing and counts per run, shown in the system statistics.

Fixed

• Order book and invoices no longer freeze when two caches refresh at once.
• Many N+1 query floods removed; large ID lists stay under the database's bind parameter limit.
• Subscribed calendars, the MS Project export of Gantt charts, the Word-to-PDF conversion and the LDAP sync repaired.

Security

• CSRF protection and complete field validation for the REST calls; access checks for all REST endpoints, enforced by an architecture test.
• Security review of the filter chain: trusted proxies, client IP detection, throttling, safe redirect URLs.
• 2FA required for sensitive pages; deleted groups never grant access rights.

Removed

• Module projectforge-wicket with all classic pages, Wicket-only i18n keys and libraries no longer used.
• AG Grid (replaced by TanStack Table), react-scripts (replaced by Vite) and JAXB.

Admin

• Legacy XML user preferences are migrated to the JSON store.

Technology

• Spring Boot 4.1, Spring 7, Hibernate 7.4, Hibernate Search 8.4, Tomcat 11.
• Kotlin 2.3, JUnit 6, Gradle 9.8, Next.js 16, React 19, TanStack Table, Vite and Vitest.
• Versions are numbered X.Y.Z and built by a release script, the version is set in one place.
