**Warning: this update (due to underlying Hived modifications) changes hived/HAF state format and requires HAF node replay, if you are using version 1.27.4.0 or earlier.** #### New features, functional improvements, and optimizations 1. Support for the new Query Supervisor (limits database resources available to database roles during a query). See documentation located here: README.md - https://gitlab.syncad.com/hive/haf/-/merge_requests/257 - https://gitlab.syncad.com/hive/haf/-/merge_requests/273 - https://gitlab.syncad.com/hive/haf/-/merge_requests/291 - https://gitlab.syncad.com/hive/haf/-/merge_requests/288 - https://gitlab.syncad.com/hive/haf/-/merge_requests/294 - https://gitlab.syncad.com/hive/haf/-/merge_requests/305 2. Dockerized environment supports --load-snapshot/--dump-snapshot options backup/restore a HAF server (including hived): https://gitlab.syncad.com/hive/haf/-/merge_requests/282 3. Optimization of `hive.operation` type conversion into textual format (improves backup/restore times): https://gitlab.syncad.com/hive/haf/-/merge_requests/292 . Right now by default `hive.operation` is converted into `bytea` literal (representing operation binary format common to blockchain storage). To use the legacy JSON-textual form, use the `body` column provided by `hive.operations_view` (also in app-specific operations view) or change your app to use the new `body_binary` column (this will improve performance). - https://gitlab.syncad.com/hive/haf/-/merge_requests/292 - https://gitlab.syncad.com/hive/haf/-/merge_requests/306 4. New function available for calculating HivePower value: https://gitlab.syncad.com/hive/haf/-/merge_requests/287 5. Complex HAF apps can now be built from multiple smaller apps: https://gitlab.syncad.com/hive/haf/-/merge_requests/277 #### Bugfixes: 1. Fixed a constraint violation while processing data in Account Metadata State Provider (common Metadata Collector provided by HAF, next to be instantiated at HAF-app level): https://gitlab.syncad.com/hive/haf/-/merge_requests/274 2. Eliminated hang of hived node while closing after earlier caught PostgreSQL related error: https://gitlab.syncad.com/hive/haf/-/merge_requests/278 3. Community reported problem related to processing forks by the HAF server: https://gitlab.syncad.com/hive/haf/-/merge_requests/285 4. Multiple app roles are allowed to create app-specific tables like also perform synchronization (simplifies and makes deployments much more secure): - https://gitlab.syncad.com/hive/haf/-/merge_requests/286 - https://gitlab.syncad.com/hive/haf/-/merge_requests/286 5. HAF functions will explicitly fail when app-specific table identifiers are too long: https://gitlab.syncad.com/hive/haf/-/merge_requests/295
