Data Crow Changelog

New in version 4.1.0

July 9th, 2015
  • This version contains the new web server as part of the existing server architecture.
  • This replaces the old web module as was delivered with version 3 but never made it into version 4. The web server delivers the following functionality:
  • Searching for items (Search..)
  • Creating new item (File > Create New)
  • Edit item (Right-Click > Edit)
  • Navigation between items (for example, open a software title, then click on it's
  • category, then see which other items have been assigned to this category, etc.).
  • Picking fields for the overview and the item form (web). (Settings > ..)
  • Full security model has been implemented
  • This web server delivers the same basic functionality (with a tad more style) as the old web module and will be expanded upon with each and every normal (4.x) delivery
  • Note: this web server is a module of the existing (since 4.0) server edition. It allows the server to serve both full (thick) clients as well as web clients at the same time. The web server uses an embedded version of Tomcat, version 8.0.23.
  • Change password on a network client caused errors / did not work.
  • NullPointerException during start up for users with very limited rights logging onto the server.
  • MP4 support for Movie File import. Many thanks Lars K�vari!
  • The Data Crow Server manual has been updated to reflect the 4.1 changes.

New in version 4.0.16 (May 31st, 2015)

  • New:
  • online service has been implemented.
  • Credentials for the server can now be supplied through the datacrow.credentials file. The Server Manual has been updated to explain this further.
  • Fixed:
  • Fixed; Picture import was not working.
  • was not updated to use the new API. Re-implemented this service.
  • New Item Wizard was closed after notifying an empty field was left empty (loss of data)
  • Update All Problems; error when renumbering.
  • Update All Problems; check box field value was always applied. Will now only be applied if checked / value has been set.
  • Update All Problems; with auto numbering enabled, the same value was applied to all. Auto numbering fields have been removed from the update all dialog.
  • The -userdir: parameter was not checked on it's format; \ or / is now appended if missing.
  • Right-click menu for child records (such as Sort, Launch File and Update All) was incorrectly executing the commands against the main record.
  • Maintain tabs; on removal of a tab the tabs was still being diplayed in the list.
  • Checkboxes, with their initial value, always caused the item to be marked as changed.
  • Stop button was not enabled when the Mass Update task was started.
  • Changed:
  • Updated the Brazilian translation; thanks ever so much Gustavo Rezende!
  • Corrected the Portuguese translation; thanks ever so much Pedro!
  • The custom label field in the General Field Settings is now represented as an editable text field to avoid confusion.
  • The Multiplayer? field of the game module has been replaced by two checkbox field "Multiplayer Game" and "Cooperative Multiplayer". This removes the Yes/No field. For existing installations the field is disabled (not removed).

New in version 4.0.14 (January 14th, 2015)

  • Data Crow server performance has been improved. Performance is still not optimal but has been increased but approximately 25%. Images are now served by Jetty, which will also be used for hosting the web application (version 4.1). Additionally the connection between client and server is reused (as it should be) instead of established on each request.

New in version 4.0.12 (January 4th, 2015)

  • Fixed:
  • User fields not visible on the form.
  • Conversion from single reference to multi-reference could fail in case of invalid entries in the database.

  • Portuguese help files, major thanks to Pedro (pmraps)!

New in version 4.0.11 (January 3rd, 2015)

  • Changed:
  • has been removed due to the restrictive authentication flow.
  • Fixed:
  • Security fix; regardless of the field security settings fields were still shown to users.
  • Fixed an issue with non US-ASCII filenames; backup process failed.
  • Issue with custom reference fields linked to the music album module. These always showed up as a "Record Label" module.
  • Item importer; child items on update of existing items failed. Trying to update an existing music album would not update the music tracks.
  • Parent key cannot be NULL exception when trying to save a music album after updating it with an online service.

New in version 3.12.5 (October 10th, 2013)

  • Fixed:
  • Ratings again shown as boxes in the quick view. Fixed - for now and ever.
  • File Importer issues fixed where items were not added to the view (but became visible after a restart). Rare occurrence.
  • Module settings for Software table view caused columns to show multiple times. Default setting has been fixed.
  • Deletion no longer allowed from Media module. Enabling this would cause deletion in general to go a lot slower.
  • Category was no longer processed correctly for the Softpedia online search.
  • Changed:
  • After an import the view will now always refresh instead of adding the items one by one immediately after they have been processed. This improves speed and just works a better.
  • Removed setting "Add directly" from file import; Data Crow will now always add items directly.

New in version 3.12.4 (October 7th, 2013)

  • Fixed:
  • Error in the "Copy Module Wizard".
  • Ratings not displayed (depending on font settings) in the quick view panel.

New in version 3.12.3 (September 9th, 2013)

  • Fixed:
  • Alter module wizard: change field; maximum length always defaulted to 255.
  • Potential issue for Template Name and Default field. These could conflict with the normal fields of the module.
  • Exported field order is now the same each time.
  • Item matching on import is now also done on the "key fields".

New in version 3.12.2 (August 16th, 2013)

  • Error loading setting if value is erroneously empty.
  • Changed:
  • Merging property items will now also update the "alternative names" field, merging items returned from online searches, etc., automatically.
  • In the past, due to performance issues, I had refrained from updating trees in case a property was changed. This has now been fully implemented; changing an icon will immediately be reflected on trees, multi-reference views and the quick view panel.
  • Added quick filter to the related items and fixed the sorting.
  • Added quick filter for the items tab of containers. Sorting cannot be fixed just yet.
  • Several minor layout changes (button alignment) such as for the tool select wizard and the update all dialog.
  • New:
  • Added a right-click option for the related items tab of the item form to remove the selected items as a reference.

New in version 3.12 (August 3rd, 2013)

  • Poor version 3.11. It only took a couple of days and then it got replaced by version 3.12. This really is for the most part a cosmetic edition. I have changed the layout a bit further. This is also a preparation for the web GUI since I want to keep the layout for both the same, for as far as possible. Due to the list of changes made and the addition of new functionality I have decided to release this as a normal version instead of a minor version.
  • New:
  • The property items overview (found in the Administration menu) gained a new tool: delete unassigned items. This will remove all properties not assigned to any other item For example a category not used in software items will be removed.
  • Another new tool for the properties module is the merge functionality. Having many categories (for example) which actually have the same meaning? Merge them all into one property. All references to the properties will be corrected (without duplication, of course).
  • The Resource Editor now has find and replace functionality.
  • Changed:
  • The screen is now much cleaner and it makes the application look simpler.
  • The file associations setting now also allows parameters to be defined.

  • Item importer will open the new items dialog to lists the imported items before saving them.
  • The module bar has been changed. Labels have been removed. Additionally the select module section has been improved. Selecting a sub module will highlight it on the main module panel.
  • Improved startup time by building forms on demand instead of on startup (where possible) 4.9 seconds on an almost empty database in 3.12 against 6.0 seconds on the same database with version 3.11.1.
  • has been changed and the information is of limited use now to Data Crow. This service has been disabled.
  • Help has been updated to reflect all of the above (press F1 once in a while just for the sake of using it).
  • The Find and Replace utility now also allows you to change one reference with another.
  • Update all now refreshed the overview after updating the items (instead of updating one by one).
  • Fixed:
  • On startup Data Crow tried to modify files in the installation folder, causing problems for Windows platforms. Data Crow can now be launched without administrator permissions.
  • Applying settings such as the language change was only properly applied after a restart.
  • Sort order of persons has been fixed (always sorts on complete name now, takes care of rewritten names).
  • Screen parts resized ever so slightly and ever so annoyingly.
  • Could not really tell which module was selected.
  • Fix for launching files from the Quick View Panel.

  • b) if you are using drive mappings across Windows / Linux the backslashes and slashes will be corrected as well.
  • The original filename is stored unmodified(!)
  • the user folder selector now checks for:
  • a) existing folder selected, containing files (continue y/n).

  • c) root folder not allowed as a Data Crow user folder.
  • Readme.txt added for the installer (which setup executable to use..)

New in version 3.10.1 (May 24th, 2013)

  • Image not saved when updated through an online service.
  • Saving the field settings for property modules also changes the quick view settings of the currently active module
  • Table view shows the same column multiple times.
  • Mass Update does not save images.

New in version 3.9.25 (May 11th, 2013)

  • Fixed:
  • More upgrade errors for old versions have been fixed. This time it's related to old columns still being present due to failed upgrades in the past. The upgrade process will now actively check for these and correct where necessary.
  • Performance bug in the table view.
  • Lend items in the loan administration are not shown by title.
  • Sometimes the items in the quick view for the container items are not sorted alphabetically
  • Changed:
  • Small change to the module selection panel.

New in version 3.9.23 (May 1st, 2013)

  • Fixed:
  • search did not work correctly.
  • OFDB online search no longer retrieved the genres correctly.
  • Templates cannot have image / image not saved.
  • Startup error in case default data is present for non existing module.
  • When selecting a new user directory through the parameters Data Crow does not set up the user folder. This results in you only having access to the user module.
  • The directory for upgrade script was not yet transferred to the new user folder. This was no problem for upgrading, however, for new conversion required Data Crow could not have any write privileges to these files.
  • Newly added fields (using the Alter Module Wizard) are now enabled by default in the general field settings.
  • Changed:
  • movie search now uses instead of web site parsing. Language setting now only applies to the localized title name. All other texts, etc, will be retrieved in English. This is a deliberate change as the web parsing is very error prone and hard to maintain. Note that you are limited to 3000 searches per hour.
  • Items shown for the container module are now sorted alphabetically.

New in version 3.9.22 (April 30th, 2013)

  • Fixed:

  • Fix for the HSQL upgrade.
  • Ratings from were no longer retrieved.
  • [Changed]
  • Various small optimizations.
  • Updated the German translation - thanks to Norman Weimar
  • Prevent users from selecting the installation folder as the user folder. The user folder is and was meant to separate the installation folder from the user folder. Mostly because the OS these days add additional security to the installation folders not allowing ordinary users to change files. You can still select a folder inside off the Data Crow installation folder.

New in version 3.9.20 (February 4th, 2013)

  • [Fixed] - Changed the restore and backup process to support backups larger than 4.28GB with the use of TrueZip.

  • Title rewriter and name rewriter work again. There was an issue after the upgrade of the database engine.
  • Changed:
  • It is not possible to specify the user directory relative to the Data Crow installation folder. Start the name with a dot (.) to make the path relative to the installation folder; ./data or .\data. This only works for the -userdir: parameter.
  • The File Importer now allows the online search to always pick the first result.

New in version 3.9.18 (January 19th, 2013)

  • Pfew, the changes I made took quite a number of releases. I hope to have it under control now. The backup and restore now works correct again. The issue with the upgrade of the database not working is mainly a security issue on the various platforms. The only solution is, when prompted, to run the command as stated in the message box from the command line / command prompt / terminal.
  • [Fixed] - Backup and restore ignores custom made modules.

New in version 3.9.17 (January 14th, 2013)

  • Changed:
  • Improved module importer

  • Start up errors for new installations of Data Crow.
  • Module images not shown on the web due to incorrect path in user directory.

New in version 3.9.16 (January 14th, 2013)

  • New:
  • You can now select a user folder where all data is stored. This helps in avoiding the Windows problem of protected folders in the C:\Program Files\ folders as well as protected folders on other systems. On startup you will be asked to select the user folder. After selecting the folder Data Crow will migrate your data to this folder and will use this folder from then on.
  • Fixed:
  • Upgrade error for Linux users.
  • Icons not shown in the multi-reference fields.

  • Templates are no longer allowed to overwrite existing values.
  • Changed the layout (default settings) for the user module.
  • Upgrades:
  • The database has been upgraded to HSQL 2.2.9 (from 1.8). This is not an easy upgrade hence the extra prompt and restart when opening Data Crow.
  • Upgraded to the latest version of JTattoo (for the Look and Feel), version from August 2012.
  • Upgraded to the latest version of IzPack for the installer.

New in version 3.9.13 (June 9th, 2012)

  • [Known issues] - The Barnes & Nobles service was broken beyond repair. Unfortunately their web service is not operational either and I have had to decide to either continue support lacking the web service or to discontinue this service. [Changes] - Improved German translation (thanks Maase!) - Create Multiple for audio tracks now starts the numbering based on the highest track number currently in use - Small changes to the loan information; removed "days till overdue" and added "status" and "# days" - The Loan administration form will now open the loan information directly on a double click [New] - book search, allows for searching both on keywords and ISBNs - Greatly improved loan administration overview; you can now search for loans and also choose to see only current and/or historic loans.

If categories are selected in the web field settings any item not having a category will not be shown. Now, they will be included. - Longer wait time for the file synchronizer when there are no items found to synchronize (high CPU usage) - Loan administration window size is not remembered. - Loan administration overview is cleared when clicking on a column header - The loan administration overview now refreshes after returning an item - Date field cannot be cleared - Data Crow GUI will not close until the database has successfully been closed. This to prevent situations where Data Crow started again while the database still in use by the previous

  • Fixed:
  • Sorting of artists, authors and other persons has been fixed.
  • Define fields in alter and create module wizard: Data Crow now correctly checks for the entered maximum length for a field.

So if you have assigned two actors to a movie, Jan Jansen and Richard Howard, the first entry will be used to sort the item (in this case Jan Jansen). Technically this has been accomplished by store the first string representation in a separate field which is used to base the sort on. This field is kept in synch with changes made (cleared in case no entries, updated with first entry in all other cases).
