VisuaLeaf v1.0.1947 Release Notes

Release Date: July 15, 2026

Two fixes you'll feel:

Copying a database to another database now copies only the collections you picked. You can select collections in a database-to-database export job, and the copy honors the selection — before, it silently copied the entire database no matter what you chose.
$out can no longer silently overwrite an existing collection. The aggregation builder now blocks the run with a clear error when the target collection already exists, and the $out / $merge forms got smarter database and collection pickers.

Also shipping: a more reliable Linux release pipeline behind the scenes.

Choose exactly what to copy — the collection picker in a database-to-database export job is now enabled, so you can copy three collections out of fifty instead of all or nothing.
The selection actually applies — previously a job with specific collections selected still copied the whole source database. Now a non-empty selection copies just those collections; leaving it empty copies everything, as before.
The picker lists the right collections — the collection list now always reflects the database you selected for the job, not the connection's default database.
No more irrelevant preview — database-level copy jobs no longer try to show a field-mapping preview that doesn't apply to them.

$out won't silently destroy data anymore. The target collection field is now a plain "new collection name" input, and if you type a name that already exists, you get a blocking error explaining that $out would overwrite it — not just a small warning icon you could miss.
Database fields have real suggestions — when writing to another database with $out or $merge, the database field now autocompletes from the databases on your connection instead of being a blank text box.
$merge suggests the right collections — the collection dropdown now lists collections from the target database you picked, not from the source database.
One terminal stage per pipeline — the builder now stops you from adding a second $out or $merge when the pipeline already ends with one, with a message explaining why, instead of letting you build a pipeline that can't run.

Overhauled the Linux release pipeline — RPM packaging, apt repository cleanup, native-library signing, and staged publishing with duplicate-upload detection — so Linux builds publish faster and more reliably.
Added an internal release runbook documenting the full publish process.

Existing database-to-database export jobs are unaffected — a job with no collection selection still copies the full database.
