Two recent pkgsrc changes that won’t directly affect how your packages are installed, but are still worth knowing about:

• Thomas Klausner made some adjustments to license handling for pkgsrc.  It’s possible to prevent packages with or without certain licenses from installing, even as a dependency.  His post contains details of the by-default accepted licenses.
• Joerg Sonnenberger has removed most instances of NO_CHECKSUM.  This will help people with poor network connections, and (I would imagine) will be better for security, too.
