NOTE: Pre-built binaries for this release are no longer available. Please use binaries from the latest release.

Changes in v1.1.15:

This release uses new link-time optimization (LTO) available starting with the LDC 1.5 compiler release. This improves the performance of most of the tools, typically by about 10% over the previous release, and significantly more in some cases. Benchmarks can be found in this slide deck from the Silicon Valley D Meetup, Dec 14, 2017.

Previous releases used Thin LTO on OS X builds. LTO was not used on Linux builds. In the OS X case, LTO was used on the tsv utilities code, but not the code from the D libraries, phobos and druntime.

The LDC 1.5 release supports LTO on both Linux and OS X out of the box, and includes support for building phobos and druntime with LTO.

This release of the tsv utilities adds support for the new LTO capabilities to the makefiles. It is not enabled by default, but can be turned on with make arguments. The prebuilt binaries have been built with LTO turned on. For more information, see Building With LTO.
