cereal v1.3.0 Release Notes

Release Date: 2019-10-25 // over 3 years ago

  • 🚀 This is a feature and bug fix release for cereal.

    🚀 This release contains a few new features, numerous quality of life improvements, and bug fixes. Many of these come from community contributions.

    📚 With this release, the develop branch is being removed in favor of a single default branch. This means that tagged releases should be used in favor of trusting the master branch as being stable. The development branch for documentation, gh-pages-develop, is also being removed. This change comes with two small side benefits: pull requests will always be against the correct branch, and it will be easy to see development activity at a glance.

    🆕 New features include:

    • Deferred serialization for smart pointers (#185)
    • 🎉 Initial support for C++17 standard library variant and optional (thanks to @arximboldi, #448)
    • 👌 Support for std::atomic (thanks to @bluescarni, #277)

    🛠 Fixes and enhancements include:

    • ✅ Vastly improved continuous integration testing (#568, #569)
    • 🛠 Fixed several issues related to compilation on newer compilers (#579, #587, #515)
    • 🛠 Fixed warnings with -Wconversion and -Wdocumentation (thanks to @WSoptics, #423)
    • 🐎 Performance improvements for polymorphic serialization (#354)

    🛠 Minor fixes and enhancements include:

    • Fixed a bug related to CEREAL_REGISTER_DYNAMIC_INIT with shared libraries (thanks to @M2tM, #523)
    • Avoid unnecessary undefined behavior with StaticObject (thanks to @erichkeane, #470)
    • 🆕 New version.hpp file describes cereal version (#444)
    • Ability to disable size=dynamic attribute in the XML archive (thanks to @hoensr, #401)

    Other Notes

    • The static checking for minimal serialization has been relaxed as there were many legitimate cases it was interfering with (thanks to @h-2, #565)
    • 🚚 The vs2013 directory has been removed in favor of generating solutions with CMake (#574)

    👀 This is not an exhaustive list of changes or individual contributions. See the closed issues for more information.
