First, "dass393" could be a version or build number. Then "javhdtoday" might relate to Java High Definition or some Java-related HD today feature. The dates in the titles are 2020-24 and 2024-03-01. Wait, maybe "04202024" is April 2020 to 2024? That could indicate a time frame, but that doesn't make much sense. Alternatively, it might be a product code with some versioning.
