For Botan 2, the tier-1 supported platforms are
- Linux x86-64, GCC 4.8 or higher
- Linux x86-64, Clang 3.5 or higher
- Linux aarch64, GCC 4.8+
- Linux ppc64le, GCC 4.8+
- Windows x86-64, Visual C++ 2015 and 2017
These platforms are all tested by continuous integration, and the developers have access to hardware in order to test patches. Problems affecting these platforms are considered release blockers.
For Botan 2, the tier-2 supported platforms are
- Linux x86-32, GCC 4.8+
- Linux arm32, GCC 4.8+
- Windows x86-64, MinGW GCC
- Apple OS X x86-64, XCode Clang
- iOS arm32/arm64, XCode Clang
- Android arm32, NDK Clang
- FreeBSD x86-64, Clang 3.8+
- IncludeOS x86-32, Clang 3.8+
- Windows x86-64, Visual C++ 2013
Some (but not all) of the tier-2 platforms are tested by CI. Things should mostly work, and if problems are encountered, the Botan devs will probably be able to help. But they are not as well tested as tier-1.
Of course many other modern OSes such as OpenBSD, NetBSD, AIX, Solaris or QNX are also probably fine (Botan has been tested on all of them successfully in the past), but none of the core developers run these OSes and may not be able to help so much in debugging problems. Patches to improve the build for these platforms are welcome, as are any reports of successful use.
In theory any working C++11 compiler is fine but in practice, we only test with GCC, Clang, and Visual C++. There is support in the build system for several commercial C++ compilers (Intel, PGI, Sun Studio, Ekopath, etc) all of which worked with older (C++98) versions of both the code and the compilers, but it is not known if the latest versions of these compilers can compile the library properly.
Branch Support Status¶
Following table provides the support status for Botan branches as of August 2018. Any branch not listed here (including 1.11) is no longer supported. Dates in the future are approximate.
|Branch||First Release||End of Active Development||End of Life|
|2.x||2017-01-06||2020?||2022 or later|
“Active development” refers to adding new features and optimizations. At the conclusion of the active development phase, only bugfixes are applied.
Custom Development or Support¶
Jack Lloyd, the primary developer, is available for projects including custom development, extended support, developer training, and reviewing code or protocol specifications for security flaws. Email him for more information.
