 ### Core
 - `lib/harmonization.py`: Change `parse_utc_isoformat` of `DateTime` class from private to public (related to #1322).
 - `lib/utils.py`: Add new function `object_pair_hook_bots`.
-- `lib.bot.py`: `ParserBot`'s method `recover_line_csv` now also handles given `tempdata`.
+- `lib.bot.py`:
+  - `ParserBot`'s method `recover_line_csv` now also handles given `tempdata`.
+  - `Bot.acknowledge_message()` deletes `__current_message` to free the memory, saves memory in idling parsers with big reports.
 - `lib/message.py`:
   - Fix add('extra', ..., overwrite=True): old extra fields have not been deleted previously (#1335).
   - Do not ignore empty or ignored (as defined in `_IGNORED_VALUES`) values of `extra.*` fields for backwards compatibility (#1335).
+- `lib/pipeline.py` (`Redis.receive`): Wait in 1s steps if redis is busy loading its snapshot from disk (#1334).
 
 ### Development
 - `bin/rewrite_config_files.py`: Fix ordering of BOTS file (#1327).
