1. Source code
The sources of the current LyX release (version 2.0.2) can be found here (also in tar.xz format). If you don't know what source code is, see the article in Wikipedia. The tarballs are gpg-signed.
2. LyX installers (binary versions)
Binary versions of LyX for installing in different operating systems can be found below. The binaries are also gpg-signed.
2.1 Windows binaries (XP/Vista/7)
The Windows installer can be downloaded here:
LyX-2.0.2-1-Installer.exe.
Installer version that include also MiKTeX as well as a binary for CygWin can be downloaded here:
ftp://ftp.lyx.org/pub/lyx/bin/2.0.2.

These installers will setup a complete LyX environment. For more information about Windows binaries, see our wiki page.
2.2 Mac OS X binaries
LyX for Mac OS X is available here: LyX-2.0.2+qt4-cocoa.dmg. Before you install LyX you need to install a TeX system such as MacTeX. There is a separate binary for Tiger (OSX 10.4): LyX-2.0.2-1+qt4-tiger.dmg.
In case the links above do not work, try this mirror.
See the LyX/Mac wiki page for further installation tips.
2.3 Linux binaries
Major Linux distributions take care of LyX binaries themselves and you will find LyX in their repositories. Some people are kind enough to prepare deb/rpm packages for latest versions. These packages are not officially supported by the LyX Team though, and if you experience problems, please try the official source distribution. For more details look in our wiki.
The versions of LyX on a variety of Linux distributions (as shipped with the vanilla distribution) can be seen on the snippet below. Note, however, that most distributions provide newer versions than the listed ones via upgrade services.
2.4 OS/2 binaries
LyX has unofficial ports to OS/2, binaries are here.
3. Additional Software
If you're not using one of the installers or packages, you may need to install some additional software.
4. Version numbers
There are certain rules how the LyX version numbers are assigned. Read the following page for detailed information.

7. Checksums & signing
We provide gpg-signed tarballs and binaries. Our GPG key ID is C7FB382D (LyX Release Manager). The signatures are found next to the tarballs and binaries.
To verify a tarball with GnuPG, do this:
gpg --recv-keys C7FB382D
to receive the key (only needed once), and
gpg --verify lyx-2.0.2.tar.gz.sig
or
gpg --verify lyx-2.0.2.tar.bz2.sig
to check the signature. Watch out for the "Good signature..." string. A similar procedure applies to the binaries.
8. Development versions
Please do not use these for any serious work! They are only provided for testing and development purposes.
