[Packages](https://docs.liquidapps.io/en/v2.0/dsps/packages.html) * it is now possible for the community to actively tune the DAPP Token Inflation rate * this inflation tuning is facilitated by DSP's creating new packages that have a configurable desired inflation rate. any changes to the DAPP Token's inflation rate is in effect for all providers * all existing packages retain the default annual inflation rate of 2.71% * a new package may select any rate between 0.0 and 5.0% * DAPP Token holders participate in the tuning mechanism by staking to packages that have an inflation rate they support * the final inflation rate is calculated as a weighted average of DAPP staked to specific inflation rates * a new table `packagext` has been added to store a packages selected inflation rate and quota cost for actions, which is indexed by `package_id`, `service`, and `provider` * the DAPP token inflation rate is recalculated with every `stake` and `refund` action * package inflation rates may not be changed after they are registered **breaking changes** * to use new dfuse push\_transaction, must compile consumer contract with new version of dappservices contract * if DSP package is not enabled in package table, signaled with boolean "1", then service will throw error on DSP, DSP package may be enabled with the `enablepkg` command: #### [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) * add `get_table_packagext` and `get_table_packagext_by_package_service_provider` to dapp-client section * add `http-max-response-time-ms = 500` to config.ini settings to avoid `deadline 2020-07-20T18:07:39.110 exceeded by 10us` error * add supported primary key types for `dapp::advanced_multi_index` * add example of instantiating `dapp::advanced_multi_index` * support new Kylin account creation query #### [@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 ` * zeus now offers versioning of boxes * zeus now offers optional `zeus unbox @[VERSION]` * can add and remove boxes with `zeus box add [VERSION] [URI]` `zeus box remove [VERSION]` * to update an existing box, run `zeus unbox @[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` * add `zeus start-localenv --phase 01-dapp-client` --phase option to target start a specific phase of the localenv * fixes * if Mac, detect and skip `--eos-vm-oc-enable` flags as they are not supported * fix endpoint link for `replay-contract.js` file * document ability to use dfuse for cleanup script * add typescript compile step for dfuse * add `zeus box create` section to zeus getting started section * update LiquidStorage upload file example with new params * add `eth_keys_per_consumer = [{ETH_PRIVATE_KEY_CONSUMER1:PRIVATE_KEY_HERE}, {ETH_PRIVATE_KEY_CONSUMER2:PRIVATE_KEY_HERE}]` to toml * prevent non-broadcast action from being broadcast * add sidechain section to replay contract #### [@liquidapps/zeus-cmd](https://www.npmjs.com/package/@liquidapps/zeus-cmd) * add `testfetch` price feed action / unit test for only using LiquidHarmony oracles for price feed fetch * add unit test for 0s unstake time dappservices * copy contracts and test folder to root so that `zeus_boxes` directory can be git ignored * add `enablepkg` command to dappservices unit tests * fixes * add `parseFloat` to `test rewards` `dappservices` unit test #### [@liquidapps/dsp](https://www.npmjs.com/package/@liquidapps/dsp) * add option to use dfuse web socket and dfuse push\_transaction guarantee in place of demux state history node on main DSP instance and supported side chains * this enables a DSP to not use a SHiP node and to instead read on chain events from dfuse and to push transactions using dfuse's push\_guarantee making transactions more reliable, a free API key is suitable enough to support low levels of traffic * to use the dfuse backend, under the new dfuse section of the toml file, set `enable` to true and provide an api key * to use the dfuse push guarantee, set the `push_enable` to true and provide a dfuse api key * to use both, enable both * add dfuse section `network` to toml, select supported dfuse network: testnet (eosio testnet), kylin, worbli, wax * add `debug` to dfuse section to enable dfuse debug logs * if dsp `head_block` set to 0, dsp will pull head block from `get_info` RPC call automatically for demux * throw error if package not enabled for DSP services * enable cleanup script support for sidechain * add `authorization` option under dfuse to use the EOS Nation community edition: | * add `replay-contract-hyperion.js` | thank you to Christoph Michel * add `max_request_retries` option to config.toml, specifies how many times to retry a blocking DSP actions such as an IPFS warmup or oracle request * add `liquidstorage_upload_limit` to config.toml, allows specification of Liquidstorage upload size limit * add to DSP eos-wrapper.js * fixes * add better error handling to CONFIRMING USAGE * fix async/await procesFn issue * fix replay contract script to enable DSPs to replay contract vRAM/IPFS data to populate a new IPFS instance * fix `0xANON` payer empty object issue #### [@liquidapps/dapp-client](https://www.npmjs.com/package/@liquidapps/dapp-client) * patch new secondary index RPC API support * updated Dapp Client to support cross chain Liquid Accounts * add dfuse as option for dapp client, able to pass API key, push guarantee, and network * add push\_transaction push guarantee function to lib #### dappservices contract * added required service pending console output to assertion message as dfuse does not return pending console output * added always false assert service pending console output to assertion message as dfuse does not return pending console output ### DSP Services: #### [LiquidAccount Service](https://docs.liquidapps.io/en/v2.0/services/vaccounts-service.html) * add cross chain support for LiquidAccounts using LiquidX * add time to live option for zeus vaccounts push-action command #### [LiquidVRAM Service](https://docs.liquidapps.io/en/stable/services/ipfs-service.html) #### [LiquidStorage

passed, updated unit test * add optional `rawLeaves` IPFS client option for backend API, example, and `client-library` #### [LiquidHarmony Service](https://docs.liquidapps.io/en/stable/developers/harmony-getting-started.html) #### [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 #### [@liquidapps/dapp-client](https://www.npmjs.com/package/@liquidapps/dapp-client) * patch new secondary index RPC API support * updated Dapp Client to support cross chain Liquid Accounts * add
