Data Crow logo (75 pix)Data Crow is bijgewerkt naar versie 3.7. Dit catalogusprogramma kan orde in de chaos scheppen van zo'n beetje elke verzameling, of het nu om boeken, cd's, dvd's, foto's of muziekbestanden gaat. Waar mogelijk wordt allerlei relevante en aanvullende informatie van internet opgehaald, zoalsIMDb , Amazon of Bol. Het programma is open source en in Java geschreven, en het is dan ook eenvoudig om aanpassingen in het uiterlijk of de functionaliteit te maken. Hieronder zijn de wijzigingen te vinden die in deze release doorgevoerd zijn:

Changed:
  • Increased the speed of the file synchronizer.
  • Items are now internally reused. Data Crow was quite generous when it came to item instances. To gain, I admit, a modest performance and memory usage gain items are now internally re-usable. As a user you will not really see this change. However, this change has such a big impact on the whole of the product that I have decided to release this version as a major release and to release it as a beta version first.
  • Several performance fixes have been applied. The external references and the additional checks performed when saving an searching for items caused the performance to drop. To overcome these issues (for large databases) the checks to see whether an item already exists have been changed;
    • For properties both the alternative names and the names are checked.
    • For all other items the external references are checked first (the PDCR in particular). Secondly a (combination of) display field is checked. Since version 3.5 Data Crow only checks on the actual string (exact match but case insensitive). This has been kept this way.
  • Views are now filled instantly resulting in a 99% performance improvement. With this change items are added to the view in about a second (regardless of the amount of items).
  • View components are now reused (reduction of item creation; lesser memory needed and performance improvement).
  • Memory needed for viewing all items now requires about 75% lesser memory. This is not a fixed memory gain as it also depends whether the items contain an image (etc.).
  • Save buttons are now removed from the item tabs of the view. Save and save all is still available from the menu bar and the tool bar.
  • Update all now saves the updates directly (!).
  • Displaying dialogs is now more controlled (technical change).
Fixed:
  • Templates could not be saved.
  • Templates are not correctly displayed in the view.
  • Template form does not show tabs as defined for the item itself.
  • Images not displayed in the web application if the images/modules folder does not exist.
  • Reference values such as actors and genres could not be saved (introduced by 3.7 beta).
  • Picture disappears when lending an item. The image reappeared after restarting Data Crow (introduced by 3.7 beta).
  • External Reference is not created when an item is updated by an online service.
  • Several problems with transparent images have been fixed.
  • MobyGames.com stopped working.
  • Items are not correctly updated in the tree / grouping pane.
  • Key navigation in table view.
  • Issues with update all functionality when loosing view focus.
  • Data Crow hangs after message "want to save changes" when navigating in the grouping pane.
  • By default the directory usage has been turned on for the File Importer. Has been changed to off by default.
  • Calendar displays February twice if the current day of the months is greater than 28.
  • "Hanging startup" on some Linux flavors.
  • Several references in text to Java 1.5; should be Java 1.6.
