| Notable changes | ||
| =============== | ||
|
|
||
| Deprecation of `fetch-params.sh` | ||
| -------------------------------- | ||
|
|
||
| The `fetch-params.sh` script (also `zcash-fetch-params`) is now deprecated. The | ||
| `zcashd` binary now bundles zk-SNARK parameters directly and so parameters do not | ||
| need to be downloaded or stored separately. The script will now do nothing but | ||
| state that it is deprecated; it will be removed in a future release. | ||
|
|
||
| Previously, parameters were stored by default in these locations: | ||
|
|
||
| * `~/.zcash-params` (on Linux); or | ||
| * `~/Library/Application Support/ZcashParams` (on Mac); or | ||
| * `C:\Users\Username\AppData\Roaming\ZcashParams` (on Windows) | ||
|
|
||
| Unless you need to generate transactions using the deprecated Sprout shielded | ||
| pool, you can delete the parameter files stored in these directories to save | ||
| space as they are no longer read or used by `zcashd`. If you do wish to use the | ||
| Sprout pool, you will need the `sprout-groth16.params` file in the | ||
| aforementioned directory. This file is currently available for download | ||
| [here](https://download.z.cash/downloads/sprout-groth16.params). | ||
|
|
||
| Mempool metrics | ||
| --------------- | ||
|
|
||
| `zcashd` now reports the following new metrics when `-prometheusport` is set: | ||
|
|
||
| - (gauge) `zcash.mempool.actions.unpaid { "bk" = ["< 0.2", "< 0.4", "< 0.6", "< 0.8", "< 1"] }` | ||
| - (gauge) `zcash.mempool.actions.paid` | ||
| - (gauge) `zcash.mempool.size.weighted { "bk" = ["< 1", "1", "> 1", "> 2", "> 3"] }` | ||
|
|
||
| The `zcash.mempool.actions` metrics count the number of [logical actions] across | ||
| the transactions in the mempool, while `zcash.mempool.size.weighted` is a | ||
| weight-bucketed version of the `zcash.mempool.size.bytes` metric. | ||
|
|
||
| The [ZIP 317 weight ratio][weight_ratio] of a transaction is used to bucket its | ||
| logical actions and byte size. A weight ratio of at least 1 means that the | ||
| transaction's fee is at least the ZIP 317 conventional fee, and all of its | ||
| logical actions are considered "paid". A weight ratio lower than 1 corresponds | ||
| to the fraction of the transaction's logical actions that are "paid". The | ||
| remaining fraction (i.e. 1 - weight ratio) are subject to the unpaid action | ||
| limit that miners configure for their blocks with `-blockunpaidactionlimit`. | ||
|

||
