eX Live 2015 has been released. TeX Live is a comprehensive TeX and LaTeX system running on Windows, Mac OS X, Linux and other Unix operating systems. For Mac OS X, a special version MacTeX 2015 is available.

Some of the changes:

• The fixes, which were previously available by explicitly loading the fixltx2e package, are now enabled by default. You still can revert to the old behavior: the new latex release package enables you to switch on backwards compatibility to a chosen release date.
• A small but useful improvement is a new float storage allocation mechanism. By default, LaTeX could handle 18 floats at a time, a higher number would cause an error. Now, you can say \extrafloats{600} to allow 600 more.
• Under the hood, it improved the support for Unicode engines.
• The release uses a new build system.
• pdfTeX now supports EXIF metadata in JPEG files.
• The shell script fmtutil has been reimplemented in Perl. Now it works with multiple formats at once, and it’s better customizable.
