[QuantLib-announce] QuantLib 1.39 released

[Luigi B. <lui...@gm...>]

QuantLib 1.39 is available for download at <
https://www.quantlib.org/download.shtml>; precompiled binaries are also
available from PyPI and NuGet for Python and C# respectively.

The list of changes for this release is at <
https://www.quantlib.org/reference/history.html>.

Note that a few recent versions of the Visual C++ 2022 compiler (from
17.14.2 to 17.14.8) had a known bug that, unfortunately, affected QuantLib
heavily and made it basically unusable. A fix was released in version
17.14.9; if you’re compiling QuantLib on Windows, make sure you're using at
least that version (or, if you can't upgrade, use the Visual C++ 2019
toolset; you can do that from VC++ 2022, as well).  Due to this, Python
wheels for Windows are not yet available; they will be shortly, when GitHub
action runners upgrade to the latest VC++ version.

If you have any problems with this release, please report them here on the
QuantLib mailing list (<qua...@li...>) or open a
GitHub issue at <https://github.com/lballabio/quantlib/issues>.
