Some changes affect existing installations. Read the release notes before you upgrade.

Thanks to the reporters and to everyone who reviewed and tested the fixes.

The Apache Roller project is pleased to announce Apache Roller 6.1.6.

Roller is a full-featured, multi-user and group-blog server written in Java, suitable for blog sites large and small.

This is a maintenance release with bug fixes and small improvements. Users of 6.1.5 and earlier are encouraged to upgrade.

A few changes affect existing installations:

• Initial setup now requires a one-time token that Roller prints to the server log. This applies both to a new installation and to a restart that migrates the database schema.
• Incoming and outbound Trackback support is removed. The endpoint no longer exists and the entry editor no longer sends pings.
• WSSE AtomPub authentication is retired. The authentication.method setting now takes basic or oauth, and an installation still set to wsse fails on startup, so change it before you upgrade.
• Media file content types are derived from file content rather than from the upload request.
• Table detection during installation is scoped to the database the connection points at. This fixes MySQL installs into an empty schema on a server that also hosts another Roller database.

Key Changes in Apache Roller 6.1.4

Safer defaults

As of Roller 6.1.4, several default settings have been updated to enhance security for multi-user weblog sites:

• HTML content sanitization: Roller now sanitizes all HTML content by default to prevent malicious content. This is controlled by the weblogAdminsUntrusted=true property in your roller-custom.properties file.
• Custom themes and file-uploads disabled by default. You can enable this feature via the Server Admin page if you trust your users, as these features can pose security risks.
• Better CSRF and XSS protection by user-specific and one-time-use salts.

Dependency updates

Over 20 mostly minor dependency updates including Spring, Eclipse-Link JPA, Log4j, Lucene, and more.

Bug fixes

Fixed some bugs that impacted category create, update and delete.

The Apache Roller project is pleased to announce the availability of Roller 6.1.3, a release that includes some minor bug fixes, dependency updates and input sanitization changes.
