🚀 Highlights​

• Memory Footprint: Revision of all memory-intensive components to resolve issues related to performance and memory usage.
• In-Memory Indexing: Introduced IndexService for efficient in-memory asset registration. It addresses a design choice made to prioritize high performance when fallback images are used extensively.
• Faster Encoding: up to 30% for WebP, 50% for JPEG and for 100% PNG (for specific access patterns and resolutions)
• Faster Scanner: Improved performance of path traversal checks by min. 20% for large datasets

Security​

• Updated Log4j to 2.26.1
• The Tomcat APR/Native Connector has been removed in favor of a pure Java connector
• CVE-2025-31650 Denial of Service Due to a Memory Leak Caused by Invalid HTTP Priority Headers)
• CVE-2024-23672 (Denial of Service due to incomplete clean-up of WebSocket connections)
• CVE-2023-46589, CVE-2023-45648 (Request smuggling caused by incorrect parsing of HTTP trailer headers)

Fixed​

• Consistency issues encountered when importing and updating directory entries have been resolved
• Significantly improved internal handling of service errors
• fsi/service/health is more precise and the HEALTHCHECK in the container works more accurately
• Hanging threads during shutdown have been fixed
• Negative counter in System Monitor fixed
• Possible User Session Overflow fixed

✨ Added​

• Added storage.jsonl log file to monitoring changes in sources
• Update search engine support to Apache Solr 10

🛠 Changed​

• JVM: Reduced default RAM allocation
• Many memory-intensive operations have been optimised
  • In response, an in-memory indexing system was introduced, which statically registers each asset. This improves performance when dealing with large numbers of assets and enables fast queries. This index requires approximately 300MB of RAM per million assets.
  • On Linux, you need to adjust the user_watcher_max system settings
• Scanner: Intervals can be set
• Improved support for video byte ranges
• Access to static directories has been changed to status 403 instead of returning an empty response
• Renderer: Optimized header handling and much faster response of 404 for non-existing assets

🧹 Removed​

• SSL certificate support in Tomcat has been removed
• Blake3 storage hashing
• Compression for static files removed

Server health service​

• The internal health service, accessible at /fsi/service/healthcheck, now uses much more internal checks to determine the overall health of the server.
• The container healthcheck was adapted according to the changes and now triggers a restart of the container more quickly.

Rename and metadata​

Fixed an issue with extra metadata added via the API not being moved in case of renaming or moving the source data.

Exit on start-up​

Fixed a server exit at startup when the server was started with an incomplete storage.

Archive support​

The unpacking of archives (TAR, BZ2) has been accelerated.

Static file responses for video files​

When delivering video files in particular, the byte-range support has been changed. . For the video container formats mov, m4v und mp4, only the first chunk is delivered for requests with range headers. This massively reduces the traffic for video playback.

Bug if Apache Solr was disabled​

If Apache Solr was disabled as the search database, an exception could occur when deleting directories. This problem has been fixed.

Storage import order​

The internal job queue that determines when images are converted for the storage has been completely re-implemented. As a result, queue processing is significantly accelerated when API uploads and file system changes occur simultaneously. The RAM memory requirements have also been significantly reduced.

WebP encoder​

A new WebP encoder based on libwebp 1.3.0 was implemented. The following encoder parameters are deprecated:

Log output when the server is stopped​

Log output for the ListBuffer indicating an error when the server was terminated has been removed. This was not an error.

Uniform time specifications for logging​

The output of dates and time ranges has been unified in all log outputs and are now human-readable.

Storage Performance​

If many files in many directories are changed, then the speed to mirroring the directory structure in storage is now much better.

Directory Cache​

The internal cache for the directory structure is now more limited based on the available RAM memory.

Fallback Images​

Rendered fallback images did not have a cache-control header under certain circumstances. This problem has now been fixed.

FSI Layers​

It's now possible to also use regular HTML content (e.g. text or videos) in FSI Layers

added parameters:

• contentInBackground - defines if content is set in background

changed API functions:

• addGroup(strParentGroupName, oParameters, (index or layer name))
• addLayer(strParentGroupName, oParameters, (index or layer name), (HTML content))
• move(layerName, targetGroup, (target index or layer name))

Bump to Java 17 LTS​

This version uses Java 17. Parts of the source code have been updated according to the possibilities of Java 17. Slight performance advantages could be measured in internal benchmarks.

Error if histogram generation is disabled​

Conversion errors could occur if histogram creation was disabled or could not be performed.

Fix disk usage performance and sizing bug​

The display of the capacity of the disk for storage was incorrect and has been fixed. The speed at which this was determined has been significantly improved.

Added some additional image formats​

We have expanded the number of supported source image formats and from this version we support the following formats:

Image type recognition​

Recognition for certain image formats has been revised and accelerated. Especially the initial scan after a reboot benefits from this improvement.

Directory images​

Fixed a problem with very small images in the Web Interface view of directories.

Fix Alpha-Channel bug​

For images without ICC color profile, the transparency channel could be rendered incorrectly. This occurred especially with PNG images with linear RGB ICC.
