+- Reworked DB model usage to use the new model interface implemented, speeded up the work by avoiding the usage of `cloneDeep` fn based on `JSON.parse(JSON.stringify(obj))` for the models. PR: [bfx-reports-framework#412](https://github.com/bitfinexcom/bfx-reports-framework/pull/412)
+- Removed duplicate buttons with the same functionality, improved and unified reports refreshing flow. PR: [bfx-report-ui#852](https://github.com/bitfinexcom/bfx-report-ui/pull/852)
