Lingua Franca Nightly

Merge pull request #2620 from lf-lang/imported-preambles

Import top-level preamble of all imported files. Previously, a reactor defined within a file that does the import would not see the top-level imports.

Lingua Franca 0.12.0

v0.12.0 (2026-04-16)

Highlights

This release offers a number of usability and infrastructure improvements. On the infrastructure side, the most significant is a refactoring of the network interface to make it less reliant on implementation via TCP sockets. A layer of abstraction has been introduced to support future development of other communication mechanisms, including encrypted communication. It also adds target properties trace-plugin and cmake-args for the C and Python targets in order to support alternative plugins for tracing such as the Xronos Dashboard. See instructions.

On the usability side, it is now possible to override parameter values of the main or federated reactor if they are primitive data types and do not control the width of multiports or banks.
This release also add utility functions for loading parameter values from a file. This is particularly useful for customizing the parameters of bank members.
For federated execution, a new --tmux option gives a convenient way to start a federation using the tmux terminal multiplexer. This separates the stdin and stdout from each of the federation components into separate windows. Another small enhancement is that the logging API now produces colored text on terminals that support colored text.
This release also adds a Python API to for user-defined tracepoints similar to those in the C target.
Finally, the diagrams now show annotations showing maxwait and absent_after attributes for federates and connections between federates. See the blog about maxwait, and the @side attributes for ports now support all four points of the compass, "north", "east", "south", and "west".

Lingua Franca 0.11.0

v0.11.0 (2025-12-05)

Highlights

This release of Lingua Franca features changes to federated execution with the C and Python targets, emphasizing the decentralized coordinator. The obscure terminology of STA and STAA has been replaced by maxwait and absent_after. These are now specified as attributes on instantiations and connections, making it possible for libraries of reactors to be agnostic about whether the reactors are instantiated as federates or within a federate. In addition, the code docs for the code generator have been greatly improved and deployed at https://lf-lang.org/lingua-franca.

This release also makes a number of improvements to the reactor-c runtime, including the ability to set and change deadlines at runtime, support for after delays with fixed-size array types, better support for variable-size arrays in Windows, and a number of bug fixes.

This release also brings syntax and semantics of federated execution into compliance with the new (still preliminary) reactor-uc runtime system and code generator that is particularly tuned for embedded platforms.

🚀 New Features

• Add DeadlineUpdateDecrease.lf & DeadlineUpdateIncrease.lf as an example of the new API function updating the deadline. #2531 (@Jakio815)

Lingua Franca 0.10.0

v0.10.0 (2025-07-21)

Highlights

This release of Lingua Franca offers significant improvements to federated execution with the reactor-c and python targets, including now generating an RTI implementation with each federation, a number of improvements to the decentralized coordinator, an optimization for the centralized coordinator (DNET, downstream next-event tag), and support for sending statically allocated datatypes (strings and arrays) across federations. This release also supports specifying a particular version of Python for the python target, provides support for more recent versions of Python, and fills in missing API functions for the python target.

This release also makes a number of improvements to the reactor-c runtime, including greatly improved documentation, a new update policy for actions with colliding tags, making API macros available in methods, making reactor names available at runtime, federated improvements (described above), and a number of bug fixes. Note that there is a new (still preliminary) reactor-uc runtime system and code generator that is particularly tuned for embedded platforms.
