Changelog for package behaviortree_cpp

3.8.7 (2024-06-26)

Backport of some build-related flatbuffers changes (#825) * From flatbuffers upstream: Fix compiler error Original author of change: avaliente-bc Backport/update from upstream flatbuffers repository. Change taken from https://github.com/google/flatbuffers/pull/7227 * From flatbuffers upstream: Fix include of string_view with C++17 abseil Original author of change: ocpalo Backport/update from upstream flatbuffers repository. Changes taken from https://github.com/google/flatbuffers/pull/7897.
Add in call to ament_export_targets. (#826) That way downstream ament packages can use this package as a CMake target.
Fixed #810 - halting of subsequent nodes in ReactiveSequence/Fallback (#817) * ReactiveSequence and ReactiveFallback will behave more similarly to 3.8 * Reactive Sequence/Fallback defaulting to allow multiple async nodes --------- Co-authored-by: Davide Faconti <davide.faconti@gmail.com> Co-authored-by: Matej Vargovcik <vargovcik@robotechvision.com>
Merge pull request #769 from bi0ha2ard/fewer_boost_dependencies depend only on libboost-coroutine(-dev) for v3.8
fix(dependency): depend only on libboost-coroutine(-dev) At least on Ubuntu, boost-all-dev depends on openmpi, which depends on a fortran compiler and gcc. This is very heavy for Docker containers where only exec dependencies are really needed.
