• Automatic Start of endpoints
  • Non-FIX endpoints (JMS, Kafka, and another) will be started with FEJ server initialization automatically. The automatic endpoint start might be changed via the startOnload property.
• Schedule endpoints start/stop within their configuration files
  • There is no need any more to define the schedule via the schdule.xml file. It can be done within the endpoint configuration. See more (TODO: add a link to FIX properties). 
• The default configuration for groups of FIX sessions
  
  • Configuration of FIX sessions may be grouped with folders and each folder may have a separate default configuration, common for all included sessions.
• Password obfuscation in FIX storages and application logs
  
  • Secret information is masked inside persisted FIX sessions data.
• The single authentication mechanism for all administrative interfaces
  • All users for different administrative interfaces are defined within the admin-users.properties file. Access to a specific interface is defined by a user role.
• RPM and DEB packages
  • FEJ may be easier installed and upgraded via Linux native packages. (TODO: add a link to the RPM installation instruction)
• FEJ system configuration files are moved to a separate folder.
  • System configuration files were moved into a separate folder (sysconf) for further easier FEJ server maintenance and upgrade. User-related configs (security, endpoint, routing configuration) remained in the conf directory.
• Encrypted keys for Remote Shell configuration
  • Remote Shell uses a private key for establishing connections. Private keys may be represented via protected keystores.
• Configuration values from environment variables
  • Secure passwords and other important configuration values may be defined as environment variables and then used within FEJ configuration. See more (TODO: link to a description of FIX session configuration).

Bugs and fixes

• SSL acceptor session with a defined acceptor port couldn't be started.
  
  • Problem description: The SSL FIX server instance wasn't defined and started during FEJ server initialization and thereby SSL acceptors can be connected as no opened SSL ports.
  • Solution: The SSL FIX server instance is initialized during FEJ server start.
• SSL Acceptor couldn't restrict connection by a specific version of SSL protocol.
  
  • Problem description: The configuration property sslProtocol works differently for an acceptor session. It defines a family of allowed SSL protocols for an acceptor.
  • Solution: A newacceptedSslServerProtocols option is added to restrict a connection via a specific SSL protocol.
• Session storage type is spontaneously changed after reloading a FIX session via FIXICC UI.
  
  • Problem description: All FIX acceptors held the link to the same instance of the configuration object and any change of such configuration affected all acceptors sessions.
  • Solution: The acceptor session receives a clone of a configuration object during its initialization.
• FEJ didn't log an error in case of failed FIX session authorization.
  • Problem description: FEJ does not log a validation error if the FIX session connects with invalid credentials or without them.
  • Solution: Logging of such a type of error was added.
• FEJ incorrectly interpreted empty username/password properties.
  
  • Problem description: FEJ expected the Logon(A) message with empty Username(553) and Password(554) tags in case of username/password properties are configured without values.
  • Solution: FEJ ignores username/password properties if they are empty.
• An acceptor session sent incoming username/password back.
  
  • Problem description: An acceptor session sent an incoming username/password back, but it just had to match them with the configured ones.
  • Solution: The acceptor session validates an incoming username/password and doesn't send them back in the Logon(A) answer.
• Sequence reset for FIX session via RemoteShell didn't work.
  
  • Problem description: The "session reset <session_id>" command returned an error message and didn't reset FIX session sequences.
  • Solution: The RemoteShell command is fixed.
• Invalid SSL parameters of the particular FIX session locked the entire FEJ initialization.
  
  • Problem description: An error during starting of a FIX session with invalid SSL parameters (invalid path to key/trustStore, invalid passwords, invalid stores types, etc.) broke the scheduler thread and it failed to start the rest sessions.
  • Solution: Errors during a session start are isolated.
• FEJ server couldn't be started from a folder that has a space in its name.
  
  • Problem description: Paths in the start script wasn't properly quoted.
  • Solution: The FEJ server start script is fixed.

...

• Kafka Endpoint can't publish/consume messages in a custom format. 
  • Problem description:  serializer/deserializer classes were hardcoded to work with FIX messages in key-value string format. 
  • Solution: Hardcode was removed and new interfaces for serialization/deserialization of MessageEvent instance into custom format were provided.
• The scheduler doesn't start the session in the middle of the day.
• Problem description:  FIX session does not start if FEJ server has started after its start time but before its stop time.
• Solution: The scheduler logic was fixed and now it can start FIX sessions if the FEJ is started during their working hours.
