### Upgrade information

### Highlights

### Features

### Improvements

* [#5199](https://github.com/spacemeshos/go-spacemesh/pull/5199) Adds smesherID to rewards table. Historically rewards
were keyed by (coinbase, layer). Now the primary key has changed to (smesherID, layer), which allows querying rewards
by any subset of layer, smesherID, and coinbase. While this change does add smesherID to existing API endpoints
(`GlobalStateService.{AccountDataQuery,AccountDataStream,GlobalStateStream}`), it does not yet expose an endpoint to
query rewards by smesherID. Additionally, it does not re-index old data. Rewards will contain smesherID going forward,
but to refresh data for all rewards, a node will have to delete its database and resync from genesis.

## 1.3.0

### Upgrade information

This release is not backwards compatible with v1.2.x. Upgrading will migrate local state to a new database.
The migration will take place at the first startup after the upgrade. Be aware that after a successful upgrade
downgrading isn't supported and might result in at least one epoch of missed rewards. See change #5207 for more

* [#5061](https://github.com/spacemeshos/go-spacemesh/pull/5061) Proof generation is now done via a dedicated service
instead of the node.

* [#5154](https://github.com/spacemeshos/go-spacemesh/pull/5154) Enable TLS connections between node and PoST service.

PoST proofs are now done via a dedicated process / service that the node communicates with via gRPC. Smapp users can
continue to smesh as they used to. The node will automatically start the PoST service when it starts and will shut it
down when it shuts down.

* [#5138](https://github.com/spacemeshos/go-spacemesh/pull/5138) Bump poet to v0.9.7

The submit proof of work should now be up to 40% faster thanks to [code optimization](https://github.com/spacemeshos/poet/pull/419).

* [#5143](https://github.com/spacemeshos/go-spacemesh/pull/5143) Select good peers for sync requests.

## Release v1.2.9

### Improvements

* increased default cache sizes to improve disk IO and queue sizes for gossip to better handle the increasing number of
nodes on the network.

## Release v1.2.8

### Improvements

* cherry picked migrations for active sets to enable easier pruning in the future

## Release v1.2.7

### Improvements

* [#5289](https://github.com/spacemeshos/go-spacemesh/pull/5289) build active set from activations received on time

should decrease the state growth at the start of the epoch because of number of unique activets.

* [#5291](https://github.com/spacemeshos/go-spacemesh/pull/5291) parametrize queue size and throttle limits in gossip

* reduce log level for "atx omitted from active set"

* [#5302](https://github.com/spacemeshos/go-spacemesh/pull/5302) improvements in transaction validation

## Release v1.2.6

### Improvements

* [#5263](https://github.com/spacemeshos/go-spacemesh/pull/5263) randomize peer selection

without this change node can get stuck after restart on requesting data from peer that is misbehaving.
log below will be printed repeatedly:

> 2023-11-15T08:00:17.937+0100 INFO fd68b.sync syncing atx from genesis

* [#5264](https://github.com/spacemeshos/go-spacemesh/pull/5264) increase limits related to activations

some of the limits were hardcoded and didn't account for growth in atx number.
this change is not required for node to work correct in the next epoch, but will be required later.

## Release v1.2.5

### Improvements

* [#5247](https://github.com/spacemeshos/go-spacemesh/pull/5247) exits cleanly without misleading spamming

Fixes a bug that would spam with misleading log on exit, such as below:

## Release v1.2.4

### Upgrade information

This release enables hare3 on testnet networks. And schedules planned upgrade on mainnet.
Network will have downtime if majority of nodes don't upgrade before layer 35117.
Starting at layer 35117 network is expected to start using hare3, which reduces total bandwidth
requirements.
