11.3.0

Maintenance release. This release only includes dependency updates and tweaks to allow the simulator to run and build under Java 16.

• The legacy swing effects serialization has been updated to be able to work with Java 16

11.2.0

• Re-introduced terminators, that were mistakenly eliminated with release 11.0.0.
• Drop-in replacement for 11.1.0
• Scafi can now clone nodes #802
• Fixed a concurrency bug in GPSTraceLoader #803
• Provide means to inform the simulator about the addition/removal of reactions in existing nodes #804
• TimeDistributions can now be cloned with Node-specific data: #79

11.1.0

• Fixed a critical bug with batch execution
• Improved error reporting

11.0.0

• Loading system renewed and written in Kotlin

• CircularArc deployment

• Protelis' ExecutionContext can be accessed from external modules
• Protelis' NetworkManager now supports modelling packet drop based on distance

9.3.0

* Improved documentation and website
* Effects for drawing layers by @paagamelo
* Fixed zigzag movement #124
* Fixed specificpositions #125
* Refactored getDestination to interpolatePositions

9.2.1

**NON-RETROCOMPATIBLE CHANGES**

* None

**POTENTIALLY NON-RETROCOMPATIBLE CHANGES**

* Code creating SAPERE LSAs via `SAPEREIncarnation.createMolecule(String)` and catching exceptions for failures may now stop working as intended,
as `null` and empty strings now cause the method to return `null` without even attempting a parse operation.
Code relying on exceptions as a form of flow control was bad anyway.

**DEPRECATIONS**

* None

**FIXED BUGS**

* Non-parsable LSAs are not sent to the SAPERE parser causing exception to be thrown.
Rather, the `SAPEREIncarnation` returns `null`.

**IMPROVEMENTS**

* None

**DOCUMENTATION**

* None

**BUILD SYSTEM AND CONTINUOUS INTEGRATION**

* None

**OTHER MINOR CHANGES**

* None

9.2.0

NON-RETROCOMPATIBLE CHANGES

• Scafi now explicitly requires a send action to be able to share information among neighbors, as Protelis does.

POTENTIALLY NON-RETROCOMPATIBLE CHANGES

• Upgraded Protelis to 13.1.0

DEPRECATIONS

• None

FIXED BUGS

• None

IMPROVEMENTS

• Scafi now supports executing end-of-round messages with arbitrary distributions, and it is feature-parity with Protelis under this point of view, thanks to @metaphori
• Smartcam is now independent of Protelis
• Upgraded Protelis to 13.1.0

DOCUMENTATION

• Add documentation for cognitive agents
• Upgraded to Orchid 0.17.6

BUILD SYSTEM AND CONTINUOUS INTEGRATION

• Use Travis wait function when deploying on Central
