WebViewer Server 2022 Changelog

2.1.0 - December 9th

  • Added fix where multithreaded image generation for documents at once could cause 1 or more documents to fail
  • Fixed issue where DWF/RVT AutoCAD formats were not being converted correctly
  • Updated Tomcat to 10.0.27
  • Apryse core update to 9.4
  • Addressed issue where document appearances would be created more than necessary
  • Made cache cleaning in both memory and disk faster and more responsive
  • Fixed error which would cause the disk cache to behave erroneously if TRN_MAX_CACHED_MB was set to 0
  • Fixed error where the cache would be deleted before necessary
  • Added new option TRN_MAX_MEMORY_CACHE_AGE_MINUTES - this option directly controls the size of the in memory cache, previously this was tied to the disk cache time limit TRN_MAX_CACHE_AGE_MINUTES and made controlling these options difficult
  • Corrected problem where unicode characters would be lost from document outlines
  • Fixed failure with status and queue checks that could cause health issues
  • Fixed issue with rendering some HTML files
  • Fixed issue where small documents (lower than 32 MB) were linearized when unnecessary
  • Fixed issue where an extra unnecessary thumbnail would be generated on document initial load
  • Made it so the server correctly picks up known web fonts for WebViewer
  • Added more status reporting in debug mode
  • Fixed problem when using a cacheKey below 40 characters and TRN_ENABLE_AUTH_SESSION would cause work to fail
  • Corrected issue where the blackbox logs within the container would be labeled with the incorrect date
  • Changed the built in health check to no longer use curl
  • Updated Cloudformation template to version 2.0.4

2.0.0 - August 16th

  • Added process seperation between Tomcat and Apryse libraries. This means document specific crashes will no longer crash the server. It should rapidly recover from any document related crash.
  • Introduces a 10% performance increase in rendering times and a 40% reduction in memory usage with high frequency requests
  • Java version updated from 8 to 17 in both Windows and Docker versions

  • Now uses better random generation for various IDs across WebViewer Server
  • Updated Java libraries in use to the latest available
  • Logging improvements
  • TRN_DEBUG_MODE when enabled will now greatly increase the amount of visible logs and when disabled less logs will be present than prior
  • The previous version removed cacheKey as the sole source of the file name when used in loadDocument, this behaviour has been restored
  • Removed curl from Docker image as it tends to be flagged for CVEs

  • Improved server initialization process for cleaner shutdown and startup
  • Improved memory handling of several low impact server jobs
  • [Windows] Fixed issue where sometimes the service would not shutdown
  • [Windows] Updated OpenJDK to 8u312-b07
