====== Version 1.3.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-1.3.0.jar|heartdroid-1.3.0.jar]]

**What's new**
  * **Important**: Improved calculaion of uncertainty over time-parametrized operators
  * **Important**: Fixed issue with incorrectly evaluation of time-based operators for states not ending on 0 (e.g. [-5min to -2min])
  * Refactoring of UncertaintyEvaluator interface (now, classes that implement it have to implement also time parametrized operators)
  * Fixed cold start problem in evaluation of temporal operators (the certainty decreases, as the missing values are nulls)

====== Version 1.2.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-1.2.0.jar|heartdroid-1.2.0.jar]]

**What's new**
  * **Important**: The ambiguous values are retained in the memory until the reasoning process is over. This allows to capure current state during the reasoning process.
  * **Important**: The time-based operators search for the historical values based on state timestamp, not value timestamp
  * Fixed issues with callbacks not working on Android
  * Fixed issues with time-based operators not including current state in evaluation

====== Version 1.1.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-1.1.0.jar|heartdroid-1.1.0.jar]]

**What's new**

  * **Important**: The way the inference mechanism selects the rules to fire changed. In case of uncertainty evaluation, in case of //fire all//, all rules that satisfies the satisfiability threshold are added and executed in conflict set.
  * Missing //fire last// conflict set resolution mechanism added
  * Added lacking mathematical operators (sin(), cos(), pow(), factorial(), etc.)
  * Fixed issues with Java 8 API on Android

====== Version 1.0.1 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-1.0.1.jar|heartdroid-1.0.1.jar]]

**What's new**

  * Fixed major bug, that caused incorrect evaluation of ambiguous values assignment during inference process
  * Fixed major bug, that prevented from using cllbacks when using HeaRTDroid as a JAR library
  * Interfaces for Actions and Callbacks were changed to better support this mechanisms purposes
  * Builders of HMR+ elements were added that allows to create Attributes, Types, etc. by providing HMR+ code in constructors

====== Version 1.0.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-1.0.0.jar|heartdroid-1.0.0.jar]]

**What's new**
  * HMR parser extended to use time-based operators and certainty factors for rules
  * HML parser removed
  * Model mutability added, which allows for dynamic changes in the model
  * DataDriven and GoalDriven inference modes added
  * Several bugfixes
====== Version 0.9.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-0.9.0.jar|heartdroid-0.9.0.jar]]

**What's new**
  * HMR parser added
  * Added WorkingMemory class that represents shared memory for all models.
  * States moved out from the model to WorkingMemory
  * Several bugfixes


====== Version 0.8.0 ======
Download link: [[https://bitbucket.org/sbobek/heartdroid/downloads/heartdroid-0.8.0.jar|heartdroid-0.8.0.jar]]

**What's new**
  * Only one inference mode: fix order.
  * Uncertainty handling mechanism based on Certainty factors added.
  * HML parser based on SAX parser
  * Callbacks and actions based on the reflection mechanism
  * Full ALSV(FD) logic implementation
