# Changelog ## [1.4.1] Upgrade dependencies. ## [1.4.0] ### Added - Add support for pending Factoid transactions to `FactomEventEmitter`. ## [1.3.0] ### Fixed - Fix an incorrect behavior of `FactomEventEmitter` that would immediately emit an event when the first listener was attached. This can be a breaking change if you are relying on this initial event to be emitted. - Fix TypeScript declaration file. ## [1.2.7] ### Added - Pass the paying EC public address as the second argument to the signing function when using signature delegation. ## [1.2.6] ### Added - `ApiError` now has a `data` field populated with the JSON-RPC error `data` field. ## [1.2.4] ### Added - Basic support of cookies. This allows session affinity for Factom Open Node (currently uses a Cloudflare load balancer). ## [1.2.3] ### Added - Added `retry` field to the `requestConfig` parameter of `FactomCli.factomdApi`, `FactomCli.walletdApi`, `FactomdCli.call` and `WalletdCli.call`. Allows to override the instance level retry strategy for a single API call. ## [1.2.0] ### Added - Added `timeout` option to `ConnectionOptions`. Allows to set a timeout for all API requests made by `FactomCli`, `FactomdCli` and `WalletdCli`. - Added a 3rd optional `requestConfig` parameter to `FactomCli.factomdApi`, `FactomCli.walletdApi`, `FactomdCli.call` and `WalletdCli.call`. Currenly only allows to specify a request timeout. ## [1.1.1] ### Fixed - Fix `FactomEventEmitter` typescript definition. ## [1.1.0] ### Added - New `FactomEventEmitter` that can emit various blockchain events (see doc for details). - New methods `composeChainCommitDelegateSig`, `composeChainDelegateSig`, `composeEntryCommitDelegateSig` and `composeEntryDelegateSig` for delegating signing of chain and entry commits to an external function (usage for hardware wallet). - `FactomCli#add*` and `FactomCli#commit*` methods now support delegating signing of the commit messages by passing a `sign` function in the options. ### Deprecated - `chunkSize` option for the `FactomCli#add*` methods has been deprecated and replaced by `concurrency`. - Depracated `signature` third argument of functions `composeChainCommit`, `composeChain`, `composeEntryCommit` and `composeEntryCommit`. Use the new `*DelegateSig` methods instead. ## [1.0.2] ### Removed - Revert the unnecessary chanage in 1.0.1 for `rewindChainWhile` (the entry already contains a blockContext). ## [1.0.1] ### Added - BlockContext populated for transactions in a `FactoidBlock` object (except `directoryBlockKeyMR` that is not available). - `rewindChainWhile(chainId, predicate, fn)`: the `predicate` and `fn` functions now receive the entry block header as a second argument. ## [1.0.0] ### Added - JSDoc of all public classes and methods. - New util functions `generateRandomFctAddress` and `generateRandomEcAddress`. - Method `toObject()` added to `Entry` and `Chain` classes. Returns a JavaScript object than can be serialized. - TypeScript definition file (RewardChain contribution). ### Fixed - Catch repeated commit exceptions properly. - Rejection of negative transaction fees. - Handling of CORS with credentials. - Handle case `Error.captureStackTrace` is undefined (Firefox). - Fix bug preventing to instanciate `FactomdCli` without params. ### Changed - More explicit ack errors. - `getTransaction` throws an `Error` if no transaction is found instead of returning `undefined`. To be consistent with `getEntry` behavior. - Redirect factomd `current-minute` API call to v2 path (intead of debug path). - Increased performance of `getEntryWithBlockContext`: fixed cost of 3 factomd API calls instead of rewinding the entry blocks of the chain. - `keyToPrivateFctAddress` renamed `seedToPrivateFctAddress`. - `keyToPrivateEcAddress` renamed `seedToPrivateEcAddress`. - `add` throws an Error when trying to create a chain that already exists. - All the `add*` functions validate by default that the paying EC address holds enough funds to pay for the commits. Can be bypassed by setting the option `skipFundValidation` to `true`. - Added a check before sending a transaction that all EC ouputs have a factoshi amount above the minimum amount required to get at least 1 EC. It can be bypassed using the `force` option of `sendTransaction` method. - Renamed `isValidFctPublicAddress`, `isValidFctPrivateAddress`, `isValidEcPrivateAddress` and `isValidEcPublicAddress` to respectively `isValidPublicFctAddress`, `isValidPrivateFctAddress`, `isValidPrivateEcAddress` and `isValidPublicEcAddress`. ### Removed - Remove `FactomCli` methods `getNodeProperties` and `getWalletProperties`. Unnecessary wrappers. - Do not expose internal constants anymore. ## [0.3.6] 2018-10-03 ### Fixed - Use Babel plugin `@babel/transform-modules-commonjs` to fix integration in the browser (broke after upgrade to Babel 7). ## [0.3.5] 2018-09-26 ### Fixed - Parsing of the descriptor index in an Admin block coinbase cancel entry. ## [0.3.4] 2018-09-13 ### Added - New FacomCli method `rewindChainWhile` that allows to iterate on a chain entry by entry. - Expose `composeChainLedger` and `composeEntryLedger` functions. - Allow manual signature of entry and chain commits (hardware wallet integration): `composeChainCommit` and `composeEntryCommit` can now take an EC public address as the 2nd argument and the commit signature as the 3rd argument. ## [0.3.3] 2018-09-10 ### Added - Options to override default API paths (`/v2` and `/debug`). ## [0.3.2] 2018-09-05 ### Changed - Renamed `addressToRcd` to `addressToRcdHash`. (breaking change) - Fixed README. ## [0.3.1] 2018-08-29 ### Changed - Upgrade to Babel 7 for the bundling process. ## [0.3] 2018-08-27 ### Added - Create a second webpack bundle `factom-struct` containing only factom.js data structures, excluding all online calls related components (FactomCli...). Util for client side applications (browser). - Check that transaction amounts are JS safe integers. - `Chain` constructor now accepts another Chain to create a deep copy of it. - FactomCli exposes `getPrivateAddress(address)` ### Changed - `Entry.Builder(entry)` now makes a deep copy of entry. - `entryBlockContext` method of the Entry builder renamed `blockContext`. - Replaced dependency on `bn.js` by `long`. - Replaced dependency on `elliptic` by `tweetnacl`. Tweetnacl is lighter and formally audited. ### Fixed - Fixed blunt error when calling `getFirstEntry` and `getEntryWithBlockContext` for a chain that is not yet included in a Directory Block. ## [0.2.6] 2018-07-26 ### Added - New universal `add(obj, ecAddress)` function that can take as a first argument an Entry, a Chain, or an iterable containing any of those classes (can be mixed). Meant to replace the use of `addEntry`, `addChain`, `addEntries` and `addChains` (kept for backward compatibility). - New `commit` and `reveal` functions that can take as a first argument an Entry or a Chain. Meant to replace the use of `commitEntry`/`commitChain` and `revealEntry`/`revealChain` respectively. ### Changed - When used with list of Entries or Chains `add` chunks the list to bound the number of concurrent promises started (default to 200). Can be controlled with an attribute `chunkSize` of the `options` argument of this method. ## [0.2.5] 2018-07-15 ### Changed - `addressToKey` doesn't accept public Factoid addresses anymore. Created explicit `addressToRcd` function to handle public Factoid addresses. (breaking change) ## [0.2.4] 2018-07-12 ### Added - Add support for RPC user/password basic authentication - Add option 'rejectUnauthorized' to allow connection to https nodes with self-signed certificates ### Fixed - Fix M1 EntryCredit blocks parsing https://github.com/PaulBernier/factomjs/issues/1 ## [0.2.3] 2018-06-26 ### Changed - Parse Admin Block entries ## [0.2.2] 2018-06-01 ### Fixed - Fix the `dist/factom.js` file. Now using webpack to build. ## [0.2] 2018-05-24 - More robust API calls: replaced factomdjs and factom-walletdjs by custom implementation with retry strategy. Possitibilty to customize retry strategy. - Usage of `factomdApi` and `walletdApi` now mimics the raw API interfaces. - Introduced the concept of 'BlockContext' for Entries and Transactions. - Added methods for manipulating addresses and cryptographic keys. Lead to removal of dependency on factomjs-util - Removal of dependencies lead to a much slimmer build! - Fixed browserify build, now generates a minified version of the distribution file. - Significantly increase code coverage (+ added code coverage tool). - Various optimizations and bug fixes
