   * Provide a regular expression for `target_frames` designing the target frames that have to be considered in the stack trace for crash replication. For instance, `.*xwiki.*` allows to consider only target frames in the stack trace where `xwiki` appears. This allows to discard frames from other projects and JDK API.
   * Set the `version` value to `<version>`.
