Now Available: Meltano v1.48.0

Today, we are excited to release Meltano version 1.48.0, which (among other things) lets you extract a subset of selected entities using new --select and --exclude options on meltano elt, improves plugin invocation and extractor catalog discovery error messages, and changes where meltano elt logs and generated plugin config files are stored.

Users who were depending on the previous locations of meltano elt logs ( .meltano/run/elt/<job ID>/<run ID>/elt.log) and extractor catalog files (.meltano/run/<extractor>/ will want to use the new locations instead: .meltano/logs/elt/<job ID>/<run ID>/elt.log and .meltano/extractors/<extractor>/

Excited to try it out?
