Opal 4.6 Released

We are pleased to announce that Opal 4.6 is now available. Opal is OBiBa’s core data management application for biobanks.

In this release:

• DataSHIELD logging: all function calls preprocessing and evaluation are logged with details for later analysis.
• DataSHIELD activity tracking: effective R execution time, count of DataSHIELD sessions are recorded per user.
• Many library dependencies upgraded, fixing some potential security issues.

This release is expected to be fully backward compatible.

Upgrade actions: Opal upgrade itself automatically except for the configuration files. This release introduces a DataSHIELD logging format and the logger tool needs to be configured accordingly. See the default configuration for the DataSHIELD logging . The change simply consists of changing the log "encoder" to a more descriptive one:

  <appender name="datashield" class="ch.qos.logback.core.rolling.RollingFileAppender">
    ...
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
      <excludeMdcKeyName>method</excludeMdcKeyName>
      <excludeMdcKeyName>created</excludeMdcKeyName>
    </encoder>
  </appender>

This release was possible thanks to the funding of the EUCAN-Connect program.
