Update notes:

With significant duration performance and usability improvements, openPDC 1.4 SP2 represents a major upgrade:
  • Completely new user interface experience
    • Designed for flexibility
    • Allows addition of new end-user custom UI screens
    • Every screen has been revisited for usability
    • Manger UI now has back and forward buttons
  • Temporal streaming data playback support
    • Allows historical playback through the native subscription services
    • openPDC Manager will now automatically support playback when a local historian is defined
    • All adapters can now be setup to connect on demand (i.e., to start only when needed)
  • Many framework level optimizations
    • A shared memory buffer pool and new parse / generate scheme was implemented to reuse internal buffers instead of always dynamically creating new ones which has greatly reduced the MB/sec of memory allocations needed.
    • Several optimizations have been made to the routing layer and new lock-free concurrent dictionaries have replaced older standard dictionaries that required critical section monitors which has reduced overall lock contention.
    • In places where synchronization was critical but overall lock time was low, new spinning locks have been implemented to reduce thread context switching.
  • Various improvements to the built-in historian
    • The API now supports multiple points per call
    • Returned data is now sorted by time then point
    • New post based request method has been added web service interface
    • Added a new historian trending tool to view historical data
    • The historian playback utility has been updated and improved for usability
  • Updates to database schema
    • Several improvements and corrections have been made to the schema
    • Additional, support for both Oracle and SQLite have been added
    • SQLite can be used in both 64-bit and 32-bit deployments without the need to install any other database software - great for substation style deployments
  • Other miscellaneous improvements include
    • Added dual-stack socket support such that IPv6 listening ports can also accept IPv4 connections
    • Improved error messages for better interpretation of exceptions
    • Keyboard / menu shortcuts added to openPDC Manager
