Changes for version 0.55

  • UPGRADE INSTRUCTIONS:
  • Because of changes to the internal data structures for some objects, the saved schema files from older versions of Alzabo will no longer work with this new version.
  • In the eg/ directory of this distribution, there is a script called convert.pl that can be used to convert your schemas.
  • It is _crucial_ that this script be run while you still have your _current_ version of Alzabo installed.
  • To repeat, DO NOT INSTALL THE NEWEST VERSION OF Alzabo BEFORE RUNNING THIS SCRIPT!
  • Now that we've got that straightened out...
  • What this script does is read an existing schema and generate code that you can run after installing the new version of Alzabo. This code will recreate your schema from scratch.
  • It should be noted that this script _will_ reverse the cardinalities of the relationships in your schema. See the entries in BUG FIXES about this.
  • If you don't like this and want it the old broken way, you can run the reverse_cardinality.pl script in the eg/ directory on your schemas. However, you can only do this _after_ installing this new version of Alzabo.
  • So the steps you should take are:
