We've just published OpenTofu v1.13.0!

We intentionally shortened the development period for v1.13.0 so that we're now more closely aligned with the Go release cycle, which means that we maximize the length of time this series can remain under security support: this series will be supported until August 2027.

However, that means that this is a relatively light release in terms of new features. The following are some highlights from the new release:

• Official releases for Windows running on ARM64 CPUs
• convert and assume... functions for reducing unknowns during planning
• Some early, experimental work towards built-in linting
• An experimental first pass of a planned new feature called "Symbol Libraries"

There are also some important changes to existing behavior that may be relevant to you:

• base64gzip function now produces slightly different results
• WinRM is no longer supported for provisioners
• Phasing out official builds for 32-bit CPU architectures
• OpenTofu on macOS now requires macOS 13 Ventura or later
