Applications using this library in previous versions should have users run `triples-upgrade-to-0.3'. • Fix for issue where adding schema would overwrite non-schema data on the same subject. 7 0.2.7 ═══════ • Add new function `triples-db-select-pred-op', which allows querying among predicates for objects with a certain relationship to values, replaces `triples-db-select-predicate-object-fragment'. • Add ability to store cons types (basically lists) as values. 8 0.2.6 ═══════ • Fix bug where the functions `triples-subjects-with-predicate-object' could return the same subject multiple times. • Fix bug where backups were causing messages about "obsolete timestamp" for some users on Emacs 28.2. 9 0.2.5 ═══════ • Fix bug where backing up a `nil' filename resulted in an error. • Fix bug where strings are wrongly escapified, distoring text especially when repeatedly saved. 10 0.2.4 ════════ • Move the `CHANGELOG.org' file to `NEWS.org' so the changes show up in GNU ELPA. 11 0.2.3 ════════ • Allow `nil' for `filename' arguments in the backup functions. This will default to backing up the default database. • Fix issue with fallback for bad backup strategies. 12 0.2.2 ════════ • Fix error behavior using Emacs builtin sqlite. Now error is rethrown instead of swallowed. 13 0.2.1 ════════ • Add backup strategy `never'. 14 0.2 ══════ • Create a default database to encourage a shared triple database. Add information on why this is an interesting idea in the README. • Add support for backups of databases via `triples-backup', and a simple way to have a sane and shared backups created with the new `triples-backups' module. • Add `triples-move-subject' which will move both a subject as well as reference to it. 15 0.1.2 ════════ • Bugfix release to remove backward compatibility with pre-Emacs 29 versions. 16 0.1.1 ════════ • Bugfix release to fix `triples-subject-with-predicate-object'. 17 0.1 ══════ • This is the initial version that contained basic triple functionality, and was integrated into GNU ELPA.
