+
+
+### Bug Fixes
+
+* capacity null when calculate bytes ([97ee2a1](https://github.com/nervosnetwork/neuron/commit/97ee2a1))
+* update tx and its outputs in different sqls ([b8fe366](https://github.com/nervosnetwork/neuron/commit/b8fe366))
+* **neuron:** use deposit timestamp to calculate phase2 dao cell apc ([abdab3f](https://github.com/nervosnetwork/neuron/commit/abdab3f))
+* **neuron-ui:** cache the genesis block timestamp in the nervos dao component instead of in global ([5274edd](https://github.com/nervosnetwork/neuron/commit/5274edd))
+* **neuron-ui:** fix the missing field in error message. ([a7dc73b](https://github.com/nervosnetwork/neuron/commit/a7dc73b))
+* **neuron-ui:** fix the missing of password request dialog ([19d07bd](https://github.com/nervosnetwork/neuron/commit/19d07bd))
+* **neuron-ui:** fix the missing word in i18n ([952ae72](https://github.com/nervosnetwork/neuron/commit/952ae72))
+* **neuron-ui:** hide the countdown if the current epoch number is greater than the target epoch number. ([2cded1c](https://github.com/nervosnetwork/neuron/commit/2cded1c))
+* add typeHash when generate dao tx ([ce5e264](https://github.com/nervosnetwork/neuron/commit/ce5e264))

+* next address order ([fffd2f0](https://github.com/nervosnetwork/neuron/commit/fffd2f0))
+
+
+### Features
+
+* Always load genesis hash and chain info when ([761a4a8](https://github.com/nervosnetwork/neuron/commit/761a4a8))
+* ChainInfo delegates Networks Service to get current chain ([0673343](https://github.com/nervosnetwork/neuron/commit/0673343))
+* If genesis hash doesn't match do not proceed to sync ([bd8e4e4](https://github.com/nervosnetwork/neuron/commit/bd8e4e4))
+* Remove ChainInfo moving its feature into NetworksService ([81f1eff](https://github.com/nervosnetwork/neuron/commit/81f1eff))

+* **neuron-ui:** hide the general settings and redirect to wallets setting ([b3e3d0e](https://github.com/nervosnetwork/neuron/commit/b3e3d0e))
+* **neuron-ui:** limit the times of guide bubble to 3 ([9b85589](https://github.com/nervosnetwork/neuron/commit/9b85589))
+* **neuron-ui:** update chain types on launch ([2cb5047](https://github.com/nervosnetwork/neuron/commit/2cb5047))
+* **neuron-ui:** update the hint of withdraw dialog ([0bec01e](https://github.com/nervosnetwork/neuron/commit/0bec01e))
+* **neuron-ui:** update the warning in withdraw dialog. ([e819439](https://github.com/nervosnetwork/neuron/commit/e819439))
+* add depositTimestamp ([108d5b1](https://github.com/nervosnetwork/neuron/commit/108d5b1))

+* If chain info couldn't be fetched set as ckb_dev ([17c1715](https://github.com/nervosnetwork/neuron/commit/17c1715))
+* Let addresses regeneration happen before sync task starts ([a52a531](https://github.com/nervosnetwork/neuron/commit/a52a531))
+* Prefer network's chain and genesis hash when syncing ([9b5b52c](https://github.com/nervosnetwork/neuron/commit/9b5b52c))
+* Preset mainnet network configuration ([1979e8a](https://github.com/nervosnetwork/neuron/commit/1979e8a))
+* Set current wallet to null if it's undefined ([6c7117f](https://github.com/nervosnetwork/neuron/commit/6c7117f))
+* Update all networks' chain and genesis hash when NetworkService ([a3ccf2d](https://github.com/nervosnetwork/neuron/commit/a3ccf2d))
+* **neuron-ui:** use calculateGlobalAPC to update Nervos DAO APC ([e96ca61](https://github.com/nervosnetwork/neuron/commit/e96ca61))
+* verify address according to chain type ([2026921](https://github.com/nervosnetwork/neuron/commit/2026921))
