MetaForms
Support for customizeable metadata using MetaForm XML documents. This allows end-users to add custom metadata project forms that can be
written to files in GUANO format, columns in .csv files (e.g. cluster.csv, id.csv, and meta.csv) or stored as fields in a searchable database. This release represents a major restructuring of how metadata is handled throughout Kaleidoscope. Details can be found at https://www.wildlifeacoustics.com/SCHEMA

Cloud Storage
Support for Cloud-based file storage and management in either Wildlife Acoustics Managed CloudAccounts or customer-managed Amazon Web Services S3 buckets.

Database
Support for fully relational database of metadata using either Wildlife Acoustics Managed Cloud Accounts or customer-managed PostgreSQL
database server.

Cloud Computing
Run batch jobs in the Cloud on Cloud-based data using Wildlife Acoustics Managed Cloud Accounts.

Clustering Improvement
Improve clustering of smaller datasets by automatically restricting parallelism that previously divided data among available cores.
