The source code and Windows installer for LyX-2.1.0beta1 are now
available at
ftp://ftp.lyx.org/pub/lyx/devel/lyx-2.1/lyx-2.1.0beta1/
I will announce the release in a few days, with the following notes:
NOTE 1 (for Autotools users):
"make check/distcheck" still fails for this beta release. This means
that there will be difficulties to install on platforms that require
these tests to pass before installing.
NOTE 2 (for Linux/CMake users):
If some of the dependencies of the test suite are not satisfied, CMake
might not be able to generate the project files. To fix this problem,
remove the following line from "CMakeLists.txt":
add_subdirectory(development/autotests "${TOP_BINARY_DIR}/autotests")
