2.1.0 - Price feed

New features

We've added price feed support to Carp! You can get prices from 3 dexs:

• MinSwap
• WingRiders
• SundaeSwap

This isn't enabled in the default execution plan, but you can see an execution plan just for the price feed below
https://github.com/dcSpark/carp/blob/main/indexer/execution_plans/dex_prices.toml#L44..L54

The price feeds are exposed via 3 APIs you can find in open API

• DexLastPrice
• DexMeanPrice
• DexSwap

For JS users, this new version can be accessed through the latest version of the carp client

Full Changelog: 2.0.3...2.1.0

2.0.3

Bug fixes

• Fix ordering of member variables in transaction/output. Note that this change will affect the order of the results of the transaction/output endpoint. See #108

2.0.2

Bug fixes

• Fixed parsing of testnet address at epoch 183 when syncing #107

2.0.1

Note: any user who started synchronizing their database from scratch using 2.0.0 will have had their Carp instance crash during epoch 0. This release fixes the issue, but you will have to restart syncing from scratch (resyncing from epoch 0 will only take a few minutes anyway). These issues did not impact users who were already done synchronizing past the Byron era

Bug Fixes

• Fix parsing of genesis block
• Fix Byron tx hash calculation

2.0.0

To upgrade from v1:

1. Run cargo migrate up to update the database
2. Bump your version of the carp-client if you are using it
3. Bump your version of cardano-multiplatform-lib if you are using it
4. Consider adding MultieraReferenceInput as part of your execution plan (note: it's now part of the default execution plan)

Features

• Add Vasil support
• Add MultieraReferenceInput task
• Add MultieraDatumTask

Chore

• Publish docker image to dockerhub
• Bump versions of Pallas, Oura and CML

Bug fixes

• Fixed unused inputs being marked with the wrong tx-credential relation
• Changed handling of duplicate keys in datum
• Fix crash on invalid CIP25 keys
• Fix pointer address range error

Carp 1.0

Release of both the Carp Indexer 1.0 and the Carp Client 1.0

Warning: this version has a known issue with the docker image. Use the next version or master to include the fix
