This upgrade will include the Runtime 1500 change proposal along with the below 2 fixes.

### Runtime 1500 release note : 
[https://github.com/PureStake/moonbeam/releases/tag/runtime-1500](https://github.com/PureStake/moonbeam/releases/tag/runtime-1500)  

Fixes :  
[https://github.com/PureStake/moonbeam/releases/tag/runtime-1501](https://github.com/PureStake/moonbeam/releases/tag/runtime-1501)

### Important updates:
* **Pending revoke/decrease** delegations will **not receive rewards** from staking anymore ([#1408](https://github.com/PureStake/moonbeam/pull/1408))
https://moonbeam.network/blog/upcoming-changes-to-staking-on-moonbeam-and-moonriver/

* Add EIP2612 (Permit) for ERC20/XC20 precompiles ([#1429](https://github.com/PureStake/moonbeam/pull/1429))  
Among many other use cases, protocols can now support gasless transactions. 

* Implement pallet orbiters ([#1374](https://github.com/PureStake/moonbeam/pull/1374))  
This change is preparing the introduction of the Orbiter program. A program meant to support the community and further decentralize the network.

 Set the new runtime code.

 # <weight>
 - `O(C + S)` where `C` length of `code` and `S` complexity of `can_set_code`
 - 1 storage write (codec `O(C)`).
 - 1 call to `can_set_code`: `O(S)` (calls `sp_io::misc::runtime_version` which is expensive).
 - 1 event.
 The weight of this function is dependent on the runtime, but generally this is very expensive.
 We will treat this as a full block.

- Problem Statement: The issue lies in the need to reimburse PureStake/Moonbeam and Polkahaus for the difference in allocations due to market volatility. The intended audience is the Polkassembly community.
- Significance: The problem is significant as it involves the financial management of two teams that successfully organized and executed Decoded 2022: Buenos Aires and NY Chapters.
- Proposed Solution: The solution proposed is to submit two treasury proposals for vote in a batch call motion, which includes the budget, difference to be covered, and rate used. The original tips have been cancelled.
- Expected Outcomes: The expected outcome is to adequately reimburse the teams for their efforts, ensuring fair financial treatment and fostering continued collaboration for future events.
