+# 0.17.0-alpha.3
+- [#602] Improve error logging for InitializerError and RustWeldingError
+
 # 0.17.0-alpha.2
 - [#579] Fix database lock
 - [#592] Fix various tests and deleted some that are not useful anymore
 - [#581] getTransparentBalanceForAccount error not handled

 # 0.17.0-alpha.1
-## Changes to Demo APP
-The demo application now uses the SDKSynchronizer to create addresses and
-shield funds. 
-`DerivationToolViewController` was removed. See `DerivationTool` unit tests
-for sample code.
-`GetAddressViewController` now derives transparent and sapling addresses 
-from Unified Address
-`SendViewController` uses Unified Spending Key and type-safe `Memo`
-
-## Changes To SDK 
-### `CompactBlockProcessor` 
-`public func getUnifiedAddress(accountIndex: Int) -> UnifiedAddress?`
-`public func getSaplingAddress(accountIndex: Int) -> SaplingAddress?` derived from UA
-`public func getTransparentAddress(accountIndex: Int) -> TransparentAddress?`
-is derived from UA
-`public func getTransparentBalance(accountIndex: Int) throws -> WalletBalance` now 
-fetches from account exclusively
-`func refreshUTXOs(tAddress: TransparentAddress, startHeight: BlockHeight) async throws -> RefreshedUTXOs`
-uses `TransparentAddress`
-
-### Initializer
-Migration of DataDB and CacheDB are delegated to `librustzcash`
-
-removed `public func getAddress(index account: Int = 0) -> String`
-
-
-### Wallet Types
-`UnifiedSpendingKey` to represent Unified Spending Keys. This is a binary
-encoded not meant to be stored or backed up. This only serves the purpuse
-of letting clients use the least priviledge keys at all times for every 
-operation.
-
-### Synchronizer
-`sendToAddress` and `shieldFunds` now take a `UnifiedSpendingKey` instead
-of the respective spending and transparent private keys.
-`refreshUTXOs` uses `TransparentAddress`
-
-### KeyDeriving protocol 
-Addresses should be obtained from the `Synchronizer` by using the `get_address` functions
-Transparent and Sapling receivers should be obtained by extracting the receivers of a UA
-````Swift
-public extension UnifiedAddress {
-    /// Extracts the sapling receiver from this UA if available
-    /// - Returns: an `Optional<SaplingAddress>`
-    func saplingReceiver() -> SaplingAddress? {
-        try? DerivationTool.saplingReceiver(from: self)
-    }
-
-    /// Extracts the transparent receiver from this UA if available
-    /// - Returns: an `Optional<TransparentAddress>`
-    func transparentReceiver() -> TransparentAddress? {
-        try? DerivationTool.transparentReceiver(from: self)
-    }
-````
-
-**Removed**
-`func deriveUnifiedFullViewingKeys(seed: [UInt8], numberOfAccounts: Int) throws -> [UnifiedFullViewingKey]`
-`func deriveViewingKey(spendingKey: SaplingExtendedSpendingKey) throws -> SaplingExtendedFullViewingKey`
-`func deriveSpendingKeys(seed: [UInt8], numberOfAccounts: Int) throws -> [SaplingExtendedSpendingKey]`
-`func deriveUnifiedAddress(from ufvk: UnifiedFullViewingKey) throws -> UnifiedAddress`

-`func deriveTransparentAddressFromAccountPrivateKey(_ xprv: TransparentAccountPrivKey, index: Int) throws -> TransparentAddress`
-
-**Added**
-`static func saplingReceiver(from unifiedAddress: UnifiedAddress) throws -> SaplingAddress?`
-`static func transparentReceiver(from unifiedAddress: UnifiedAddress) throws -> TransparentAddress?`
-`static func receiverTypecodesFromUnifiedAddress(_ address: UnifiedAddress) throws -> [UnifiedAddress.ReceiverTypecodes]`
-`func deriveUnifiedSpendingKey(seed: [UInt8], accountIndex: Int) throws -> UnifiedSpendingKey`
