Nextcloud 33: Updated Summary of What Is New
Based on the February 18, 2026 changelog for Nextcloud 33.0.0.
Overview
Nextcloud 33 introduces a broad set of improvements across file management, sharing, collaboration, administration, developer APIs, performance, and security. The release also continues the platform’s architectural modernization with major frontend migrations, backend cleanup, and expanded support for new infrastructure and task processing capabilities.
File Management Enhancements
Nextcloud 33 improves file management with faster and more efficient preview handling, including previews for large remote files without full download and on demand preview migration. File system operations are more robust through path specific filesystem setup, better repair tooling, and improved handling of storage IDs and paths.
The files app also gains a range of usability improvements. These include better drag and drop behavior, improved copy and move handling, warnings when files would become hidden, and more efficient file tree initialization. Trash bin behavior has also been strengthened with improved expiration handling, clearer retention behavior, better size propagation, and more reliable deletion logic.
Sharing and Collaboration Improvements
Sharing receives major updates in Nextcloud 33. Public shares can now expose template creator lists, use improved sidebar APIs, and support more flexible password and permission handling. Federated sharing has also been improved with better interoperability, support for folder shares in cloud federation, and more reliable external and trusted server behavior.
Collaboration features are also expanded. Comments now support Markdown, public share access has been refined, and share target repair logic has been improved. The platform also introduces partial share providers and partial mount providers, which strengthen the flexibility of sharing related integrations.
Activity App Enhancements
The Activity app now includes a bulk activity option and receives several stability improvements, including better digest handling, improved error resilience, and fixes for activity insertion and email related workflows.
User Management and Security
User and administrator workflows are significantly improved in version 33. The release introduces a UserConfigChangedEvent, expands admin delegation tooling, and improves LDAP configuration through a rewritten setup wizard and local caching of frequently requested mapping data.
User management also benefits from better group handling, improved column visibility controls, stronger display name handling, and more robust account related behavior. On the security side, Nextcloud 33 improves login protection by hiding passwords on form submission, supports more flexible rate limit settings, strengthens app password handling, and improves two factor related defaults and setup checks.
Theming and User Interface Updates
Nextcloud 33 continues the platform wide transition to modern frontend technology. A large number of apps and settings pages have been migrated to Vue 3 and TypeScript, including theming, LDAP, trash bin, reminders, OAuth2, profile, updater, login flow, and public share authentication.
The user interface also receives many refinements. These include more consistent settings components, improved action labels, updated app settings layouts, better public page footer behavior, a remember me checkbox, and an office switcher with feature comparison. Overall, the release improves consistency, maintainability, and usability across the interface.
Calendar and Contacts Enhancements
Calendar and contacts functionality is improved in several areas. Calendar related changes include more robust CalDAV handling, better invitation support, automated appointment creation, improved room and resource calendar creation, and stricter behavior when calendar federation is disabled.
Contacts and identity discovery are also improved through better default contact handling, support for deleting recent contacts, filtering contacts by team, and federated user and group search support when managing team membership.
Developer and API Improvements
Nextcloud 33 adds a number of important platform and developer features. These include INodeByPath, typed events for system tags, improved route metadata, authenticated webhook listener support, installation completed events, and new APIs for retrieving users for sharing.
Task Processing sees especially strong expansion. New features include internal task types, batch endpoints, user facing error messages, triggerable providers, OCR task support, and watermarking related task attributes. The release also introduces Snowflake ID generation support and an OpenMetrics exporter for improved observability.
Performance and Security Enhancements
Performance work in version 33 is extensive. Improvements include direct pre signed S3 download links, better S3 retry handling, optimized user mount cache behavior, faster mount lookup logic, preview storage improvements, and HTTP/2 plus brotli support in the internal HTTP client.
Security and operational reliability are also strengthened through recurring CA bundle updates, code signing revocation list updates, improved logging, better cache behavior, stronger exception handling, and PostgreSQL SSL and TLS support.
Miscellaneous Improvements
The release also includes a wide range of smaller but important updates. These include support for more MIME type aliases, improved setup checks, better office and mount management, support for updating user public keys, better compatibility with external storage, and broader cleanup of deprecated APIs and legacy JavaScript patterns.
Many reliability fixes are also included across files, settings, federation, previews, task processing, and app integration flows.
Dependency and Security Updates
Nextcloud 33 updates many core backend and frontend dependencies, including Vue, Vite, WebDAV, Doctrine DBAL, Symfony, Guzzle, PHPUnit, Cypress, and Sass. It also raises key platform requirements, including PHP 8.2 for Nextcloud 33, adds a PHP 8.5 polyfill, updates supported PostgreSQL versions, and removes older compatibility paths such as Oracle 11 support.
These updates improve performance, compatibility, long term maintainability, and security across the platform.
