| Made it so that the performance of monitor is improved. | | [INDY-1660](https://jira.hyperledger.org/browse/INDY-1660) |
| Made it so that Stewards, can have a script that can generates Proof of possession for their BLS key. That value can now be used in a NODE txn. | | [INDY-1588](https://jira.hyperledger.org/browse/INDY-1588) |
| Added Support Proof of Possession for BLS keys. | | [INDY-1389](https://jira.hyperledger.org/browse/INDY-1389) |

| **Known Issue:** Upgrade failed on pool from 1.3.62 to 1.4.66. Note that INDY-1447 was fixed in indy-node 1.5.68, but it still presents in indy-node 1.3.62 and 1.4.66 code. | **So, some of the nodes may not to be upgraded during simultaneous pool-upgrade.** If this problem will appear, stewards should perform manual upgrade of indy-node in accordance with this [instruction:](https://docs.google.com/document/d/1vUvbioL5OsmZMSkwRcu0p0jdttJO5VS8K3GhDLdNaoI)**(!)** To reduce the risk of reproducing INDY-1447, it is **recommended to use old CLI for pool upgrade.** | [INDY-1447](https://jira.hyperledger.org/browse/INDY-1447) |
| | | | |

Upgrade Scripts:

**Pool upgrade from indy-node 1.3.62 to indy-node 1.6.73 should be performed simultaneously for all nodes due to txn format changes.**

Additional Information:

**All indy-cli pools should be recreated with actual genesis files.**

**For more details about txn format changes see** [**INDY-1421**](https://jira.hyperledger.org/browse/INDY-1421) **.**

**There are possible OOM issues during 3+ hours of target load or large catch-ups at 8 GB RAM nodes pool so 32 GB is recommended.**
