Changes for version v1.10.0 - 2026-10-23
- Release v1.10.0 for for CLDR 49
- Added the data_aliases table, which stores the aliases of root as rules, and the resolve() method, which follows them after locale inheritance and before root, as UTS #35 specifies for aliases with source="locale". An alias of root points to the data of the locale being resolved, not of root: for instance, the Japanese calendar months of fr are its Gregorian months (janvier), not those of root (M01).
- Added the data_alias() and data_aliases() methods.
- scripts/create_database.pl: the aliases of root are now converted into rules in the data_aliases table, and an alias that cannot be mapped to a table is fatal. Root no longer causes a fatal error for the British and Irish metazones of CLDR v49, which are aliased to the GMT metazone of the locale being resolved.
- Added missing clone() method in subclass Locale::Unicode::Data::Exception
- Fixed a DBD::SQLite thread ownership error during interpreter shutdown. Added a CLONE method to discard inherited database and prepared statement caches, ensuring that child threads establish their own SQLite connections.
- Updated the END block to perform ordered cleanup of cached prepared statements and database handles only in the main interpreter. Child threads rely on DBI's normal handle destruction, avoiding explicit calls to finish() or disconnect() on handles owned by other threads. This preserves the deterministic cleanup introduced to prevent SQLite use-after-free crashes on OpenBSD.
- Removed the redundant database handle reference stored in each object. The constructor still validates the database connection, but no longer retains the handle in $self->{_dbh}.
- Updated database_handler() to retrieve the connection through _dbh(), ensuring that callers receive the database handle associated with the current thread or process.
