 +## v0.8.0
 +
 +### Notable Changes
 +
 +#### Configure wallet timeout
 +
 +Previously, the default timeout period before a wallet autolocked itself was set
 +to two minutes. Now, a new method `wallet.config()` accepts a configuration
 +object consisting of currently one property `timeout` indicating the timeout
 +period in seconds between 10 and 600 (10 minutes). If left unconfigured, the
 +default is still two minutes.
 +
 +#### Check for lock status
 +
 +A new property `wallet.isLocked` indicates if the wallet's Vault is in a locked
 +state.
 +
 +### Other Changes
 +
 +Vault timer includes a simple interval ticker to keep the worker from sleeping.
 +
 +Developer build now includes sourcemaps for easier debugging.
 +
 +Some new tests have been added and some existing ones fixed.
 +
 +
 +
 +## v0.7.0
 +
 +### Notable Changes
 +
 +#### Wallet accounts use Map
 +
 +Since `libnemo` allows any arbitrary account index within the valid index range
 +to be derived from a wallet, iterating arrays can be catastrophically slow. A
 +custom class with a custom iterator implementation was used previously, but to
 +take advantage of engine performance optimizations geared towards built-ins, it
 +now uses the Map class instead.
 +
 +### Other Changes
 +
 +Accounts implement toJSON() method to stringify all relevant properties.
 +
 +Tests are type checked, and the custom assert implementation in tests uses type
 +guards to inform subsequent code.
 +
 +README and package description updated.
 +
 +
 +
 +## v0.6.0
 +
 +### Notable Changes
 +
 +#### Minification support
 +
 +Due to how the `Vault` worker was constructed, the build system could not take
 +advantage of all minification features without breaking how variable names and
 +class names are resolved in the worker itself. This version refactors how the
 +worker code is constructed in such a way that enables the build system to apply
 +name mangling and minification while bundling. This also enables other
 +frameworks like Angular to bundle `libnemo` without further breakage.
 +
+ ## v0.5.4
+ 
+ ### Notable Changes
+ 
+ Fix restored wallets with undefined type.
