This releases finalizes support for scheduled transactions and HAPI protobuf v0.12. Two new schedule specific REST APIs were added including /api/v1/schedules and /api/v1/schedules/:id. The former lists all schedules with various filtering options available and the latter returns a specific schedule by its schedule ID.
GET /api/v1/schedules?account.id=0.0.1024&schedule.id=gte:4000&order=desc&limit=10

}In HAPI v0.12, new memo fields were added to all entity types bringing parity across all services. Mirror node now supports the new fields including for update operations where the memo field can be set to null, empty string or a non-empty string to keep, clear or replace the existing memo, respectively.
Historically, the importer application has always downloaded stream files and saved to the filesystem in one thread then read those files and ingested them into the database in another thread. This has sometimes caused the database and filesystem to get out of sync and require manual intervention to fix. It also makes the importer stateful and as a result could not support running multiple instances for high availability.
With this release, we've removed the need for importer to read and write to the filesystem. Instead, the downloader and parser threads now communicate via an in-memory queue. To accomplish this, we also had to remove the t_application_status table in favor of calculating the last successful file directly from the stream file tables. In addition to fixing the aforementioned issues, the removal of the filesystem has resulted in a 5% latency improvement.
Other changes include adding an index field to record_file table to simulate a blockchain index and updating our Google Marketplace to v0.27. Also, we added support for the v5 stream files to the check-state-proof client app.
