### Release highlights

Release v0.73 enables [HIP-1261 Simple Fees](https://hips.hedera.com/hip/hip-1261) and [HIP-1313 High-Volume Entity Creation](https://hips.hedera.com/hip/hip-1313) on mainnet, and completes [HIP-1357 Block Node Rewards](https://hips.hedera.com/hip/hip-1357) and [HIP-1137 Block Node discoverability](https://hips.hedera.com/hip/hip-1137). Together, these changes make fees easier to predict, add optional burst capacity for entity creation, and establish on-chain Block Node discovery and operator rewards.

<Accordion title="What's new in Release v0.73?">
**Simple Fees (HIP-1261)**

Enables a **base + extras** fee model in USD (system file `0.0.113`), with node, network, and service components. Fees are deterministic across nodes so SDKs and mirror nodes can match consensus-node calculations.

**Benefits**

* Simplifies fee estimation compared with the legacy resource-based schedule
* Expands Simple Fees coverage across additional transaction types and queries

**High-Volume Entity Creation (HIP-1313)**

Adds optional `high_volume` entity-creation capacity using separate throttle buckets and utilization-based pricing (`highVolumeRates`) in the Simple Fees schedule. Requires HIP-1261; standard throttles and pricing are unchanged unless the flag is set.

**Benefits**

* Supports higher burst entity-creation rates without consuming standard throttle capacity
* Records `high_volume_pricing_multiplier` in transaction records for transparent auditing

**Tier 1 Block Node Operation Rewards (HIP-1357)**

Distributes additional daily rewards from account `0.0.801` to consensus node accounts that operate an eligible Tier 1 Block Node (PUBLISH API) listed in `associated_registered_node`, based on `targetYearlyBlockNodeRewardsUsd`.

**Benefits**

* Compensates block-stream operators who meet both consensus and block node obligations
* Adds per-node reward distribution and eligibility metrics for monitoring

**Block Node Discoverability (HIP-1137)**

Completes the on-chain registered-node registry so operators can publish Block Node endpoints (including multiple APIs per endpoint) via `AddressBookService` transactions. Clients can discover nodes from network state instead of static configuration.

**Benefits**

* Provides a trustworthy, operator-managed source for finding Block Nodes
* Links consensus node accounts to registered nodes for rewards and operations
