 +## v0.5.2
 +
 +### Notable Changes
 +
 +Remove async-await from new Vault functionality in favor of Promise chaining
 +(see [v0.4.0](#v040) for details).
 +
 +
 +
 +## v0.5.1
 +
 +### Notable Changes
 +
 +Fix type definitions for unit denomination `convert()` function overloads.
 +
 +
 +
 +## v0.5.0
 +
 +### Notable Changes
 +
 +#### Sign arbitrary data with Wallet
 +
 +The ability to "log in with Nano" is gaining traction, and while the `sign()`
 +function from `Tools` allows signing arbitrary string data using a private key,
 +there was no way to sign with a `libnemo` wallet which does not expose private
 +keys. Now, the `sign()` instance method of the `Wallet` class has been updated
 +to accept one or more strings of data, hash them to a 32-byte value using
 +BLAKE2b, sign with a given account index, and return the signature. Note that
 +the data is first hashed only to maintain compatibility with other Nano tools; a
 +future update could enable signing full-length messages without hashing them.
 +Also note that the Nano app for Ledger wallets still have a bug which prevents
 +them from signing nonces.
 +
 +#### Implement missing password update method
 +
 +The `Vault` class for wallet secrets supports an `update` action to re-encrypt
 +them using a new password if the wallet is unlocked. However, the `Wallet` class
 +itself did not have a method to make this request to its vault. This has now
 +been implemented.
 +
 +### Other Changes
 +
 +The `convert()` tool now supports denomination output as a float in addition to
 +string and bigint.
 +
 +Some functions extracted to separate files to improve organization.
 +
 +Type definitions updated.
 +
 +Tests added or updated to accomodate new features.
 +
 +
 +
 +## v0.4.1
 +
 +### Notable Changes
 +
 +Redefine Vault worker class members as instance properties instead of static
 +properties and initialize the worker with `new` instead of an `init()` method
 +which allows it to privatize its properties again.
 +
 +
 +
 +## v0.4.0
 +
 +### Notable Changes
 +
 +#### Vault abandons async-await
 +
 +Bundlers try to optimize code based on features supported by the target browser
 +environment as well as work around shortcomings or bugs. Sometimes this results
 +in mangling code that would otherwise be acceptable. Private class fields and
 +async-await are two such features that bundlers are eager to refactor. This is
 +particularly problematic for the Vault worker in `libnemo` due to how it loads
 +as a stringified data blog. To avoid this situation, async-await statements have
 +been replaced by traditional promise chaining in Vault-related classes, and
 +private members that were being hoisted outside the class scope (and thus being
 +lost when loading the worker) are now initialized in a static method so that
 +they keep their place in the class as designed.
 +
 +#### BLAKE2b outputs bytes only
 +
 +This change is intended purely to simplify the structure of the BLAKE2b hashing
 +implementation. The `digest()` method no longer accepts any parameters and will
 +always output bytes; hex string is no longer an output option, and the bytes
 +should be converted if necessary.
 +
 +### Other Changes
 +
 +Fixed some erroneous JSdoc comment documentation.
 +
 +
 +
+ ## v0.3.2
+ 
+ ### Notable Changes
+ 
+ Fix type comparison to undefined when restoring Wallets from database.
+ 
+ 
+ 
  ## v0.3.1
