Security Patches

  • [MTC-25556] [MTC-25555] If a compressed file (tar.gz or zip) contains a symbolic link or absolute path, an error will now occur at decompression.

New And Improved Functions

Content Sync

Immediate delivery changed to background processing

In previous versions, when immediate delivery was executed, processing was done in real time on the browser. However, when the number of target files is enormous, there was a problem that processing timed out. In order to solve this problem, we changed the processing method from real-time distribution on the browser to background distribution using run-periodic-tasks.

When immediate delivery is registered, distribution processing is executed when the next run-periodic-tasks is executed. A notification e-mail is sent when distribution is started.

In environments where run-periodic-tasks is not executed periodically, immediate delivery is not performed.

Following this change, there are some restrictions.

  • When immediate delivery is executed for multiple server delivery settings, processing is executed in the order in which they were registered.
  • For the same server delivery setting, if scheduled delivery is executed before immediate delivery, immediate delivery will not be executed.

Clarification of authentication error

Changed the error message to be appropriate when user authentication error occurs when connecting to FTP server.

Support TLS 1.1 / 1.2

When connecting to ftp server with FTP over SSL, connection using TLS 1.1 / 1.2 has been enabled.
