Changelog

This is the manual for older MicroStream versions (Version < 5.0).

The new documentation (Version >= 5.0) is located at:

https://docs.microstream.one/

2.1

Features

• Android support MicroStream is now Java-wise fully compatible with Android.

• Replaced all usages of java.util.File with java.nio.file.Path to allow using custom file implementations.

• Improved skipping functionality of Storers (see EmbeddedStorageManager#createStorer and Storer#skip).

• The class Lazy is now an interface to allow custom implementations. See Migration guide below.

Bugfixes

• Fixed a few minor bugs in the skipping functionality of Storers.

• Fixed a bug where files remained locked after the storage was shut down.

• Fixed a bug where files remained locked after an exception in storage initialization.

• Enums defining an abstract method are now handled correctly.

• By default, all threads created by MicroStream now start with the prefix "MicroStream-". This can be customized by the new interface StorageThreadNameProvider.

• Fixed a NullPointerException in import.

• Fixed a bug that caused enums with a certain field layout to be loaded inconsistently.

• java.util.Locale is now persisted and created using Locale's #toLanguageTag and #forLanguageTag.

Migration Guide

In the directory of an existing storage, in the TypeDictionary file (default name "PersistenceTypeDictionary.ptd"), all occurances of "one.microstream.persistence.lazy.Lazy" must be replaced with "one.microstream.persistence.lazy.Lazy$Default".
