Release Notes: Guile error messages now display the file name and the line number of the source template file.
Release Notes: When an option is configured out (via ifdef or ifndef attributes), it can now still show up in usage text as "disabled". AutoOpts now supports a new option attribute: aliases. This option will be listed in the usage text, but will be handled exactly as if the aliased-to option were specified. AutoGen tracing output now allows you to prefix a file name with shell-style append redirection to indicate that the output appends to the file (i.e. >>file).
Release Notes: A new function time-string->number will convert various time duration strings (a la ISO-8601) into a count of seconds. There are various obscure cleanups.
Release Notes: Minor tweaks. Mostly the vehicle for AutoOpts.
Release Notes: The --usage option is now supported. Suppression of configuration file parsing with environment variables now works correctly. Cleanups were made for Windows and Debian packaging.
Release Notes: Some configuration issues were fixed.
