This version of LDC will make Lime CRM Desktop Client load and save data faster and more resilient.

==== Technical Details ====

  * Improved robustness for deadlocks
      * Isolation: All read operations now default to read uncommitted to reduce problems with deadlocks.
      * Priority: Read operations will have lower priority to avoid blocking (expensive) updates.
      * Stability: Fixed bugs in error handling for deadlocks that previously resulted in crash, which resolved the deadlocks.
  * Improved scalability
      * Large cache objects now stored as files
      * Reduced memory footprint
      * Stateless operation
      * Access to full 4Gb address space
      * Fixed several memory leaks that resulted in memory fragmentation
  * Improved performance
      * Optimized streaming and conversion for data
      * Optimized string and buffer handling
      * Native integration with Redis for persistent caching
      * Native C++-level object model instead of COM+ to avoid internal overhead
  * Improved handling of data structure
      * Full support for multilevel caching (SQL, Redis and COM+)
      * Refactored detection of updates
      * Cache semaphore to avoid multiple parallel execution of expensive operations that populate cache
      * Unified internal model
  * General improvements
      * Fixed internal threading issues
      * Native support for logging crashes
      * More detailed logs for known issues
