## 2.0.5328

**breaking changes**

* all unboxed `zeus` boxes will need to be re-unboxed to support the new `zeus_boxes` architecture

#### [docs](https://docs.liquidapps.io/en/stable/)

* add CoVax chain section for becoming BP or DSP
* add example chains section of LiquidX chains
* add [EOS Block Producer Benchmarks](https://www.alohaeos.com/tools/benchmarks#networkId=21\&timeframeId=2) | courtesy of [Aloha EOS](https://www.alohaeos.com/)
* use eos 2.0.5
* update documentation to support `zeus_boxes` refactor
* add `chain-threads=8` `eos-vm-oc-compile-threads=2` to nodeos example `config.ini` in docs
* add [LiquidStorage section](https://app.gitbook.com/s/-MTfSc9O76OFJpqcb3QC/release-notes/developers/storage-getting-started)
* update [LiquidAccounts section](https://app.gitbook.com/s/-MTfSc9O76OFJpqcb3QC/release-notes/developers/vaccounts-getting-started)
* update [LiquidVRAM section](https://app.gitbook.com/s/-MTfSc9O76OFJpqcb3QC/release-notes/developers/vram-getting-started)

#### [@liquidapps/zeus-cmd](https://www.npmjs.com/package/@liquidapps/zeus-cmd)

* use 8887 instead of 8889 for state history port to match DSP docs
* skip `01-dapp-client.js` if built
* add price feed example, price feed uses LiquidHarmony's oracles and LiquidScheduler's cron to fetch a price periodically and only use CPU when the price has changed from the last recorded price by more or less than 1%
* add `'--eos-vm-oc-compile-threads=4'` and `--chain-threads=4` to local nodeos
* update `zeus` to modularize logic into `zeus_boxes` directory making `zeus` more like `npm`, to create or unbox a new box start with `zeus box create [name]` then if you wish to unbox and existing box `zeus unbox <BOX>`
* zeus now offers versioning of boxes
  * zeus now offers optional `zeus unbox <BOX>@[VERSION]`
  * can add and remove boxes with `zeus box add <BOX> [VERSION] [URI]` `zeus box remove <BOX> [VERSION]`
  * to update an existing box, run `zeus unbox <BOX>@[VERSION]`, if no version specified, latest used, will unbox everything again with new version
  * to only add new boxes, unbox after update with `--no-update`
* fixes
  * if Mac, detect and skip `--eos-vm-oc-enable` flags as they are not supported

* added warning to ensure `trace-history = true` set in nodeos `config.ini`
* add how many blocks behind the head block in demux heartbeat
* add `DATABASE_TIMEOUT` to sample toml, adjust time before database connection times out
* add `DEMUX_PROCESS_BLOCK_CHECKPOINT` to sample toml, amount of blocks to pass before updating database with last processed block
* add `disabledServices` to ecosystem file to prevent pre-alpha services from being setup
* add `DEMUX_MAX_MEMORY_MB` option to ecosystem file to set maximum amount of memory that can be used by demux
* add `dsp_account_permissions` option for each sidechain
* fixes
  * handle `TypeError: Cannot read property 'this_block' of undefined` in demux

#### [LiquidAccount Service](https://docs.liquidapps.io/en/v2.0/services/vaccounts-service.html)

* add cross chain support for LiquidAccounts using LiquidX

#### [LiquidVRAM Service](https://docs.liquidapps.io/en/stable/services/ipfs-service.html)

* add cross chain reading of vRAM table data

#### [LiquidStorage Service](https://docs.liquidapps.io/en/stable/services/storage-service.html)

* add dapp-client examples for `get_uri.ts`, `unpin_public_file.ts`, `upload_archive_to_liquidstorage.ts`, `upload_file_to_liquidstorage.ts`, `upload_public_file_from_vaccount.ts`
* add sidechain storage unit test
* add `zeus storage upload <ACCOUNT_NAME> package.json <ACCOUNT_PRIVATE_KEY>` and `zeus storage unpin <ACCOUNT_NAME> <IPFS_URI_RETURNED_ABOVE> <ACCOUNT_PRIVATE_KEY>` zeus commands

#### [LiquidHarmony Service](https://docs.liquidapps.io/en/stable/developers/harmony-getting-started.html)

* add check to ensure each DSP only returns one oracle response
* add hook to assert on oracle fetch before geturi is fired
* add `Oracle minimum threshold check` unit test
* reduce oracle retries to 10 from 100
* add `shouldAbort` `eosio::check` handler for aborting oracle service request
* add `echo` oracle, which uses the same structure as `http` or `https` however the uri is replaced with a desired return value. This return value must be a base64 encoded string.&#x20;
  * `echo`: Mimics a GET request that returns text
  * `echo+json`: Mimics a GET request that returns JSON
  * `echo+post`: Mimics a POST request that returns text
  * `echo+post+json`: Mimics a POST request that returns JSON&#x20;

#### [LiquidScheduler Service](https://docs.liquidapps.io/en/stable/developers/cron-getting-started.html)

* run exponential backoff forever, was 10 retries max
* add `shouldAbort` `eosio::check` handler for rescheduling cron without CPU
