I use the API to query change data for auditing and metrics. Currently the API only allows me to pull changes by Pipeline Instance, and I can only pull the past 100 instances. This also results in duplicate changes since a single change frequently appears in multiple pipelines. I need the ability to query for changes, hopefully with project, group, and timestamp query parameters (similar to the parameters I can use to filter pipeline instances). It would also be helpful to filter by managed/unmanaged.
