[asdf-announce] ASDF 2.018 released

[Faré]

Dear CL users,

I released ASDF 2.017.27 as 2.018.

Please test and upon success update your implementations and distributions.

Since 2.017, we have the following improvements:

 Bugs:
  * Solved a bug due to ASDF reusing components even when the ASDF definition
   has changed wildly, leading to bad behavior in incremental compilation
   and sometimes total failure of compilation of a new version.
   (Thanks to Xach for reporting and RPGoldman for fixing.)
  * Fix an issue with ASDF doing the wrong thing in case of a clock skew,
   thanks to Andreas Fuchs.
  * Simplification of the internals of perform-with-restarts and
   traverse's do-dep, that should fix some corner cases and make it
   easier to extend or further fix. There scarily doesn't remain
   any unedited code from Dan Barlow's original ASDF, though
   much of the interface design is preserved.
  * Upgrade code slightly simplified, with a particular fix for CLISP;
   it is now tested on all supported implementations, not just SBCL.
  * Improvements to tests and documentation.

 Portability:
  * Many implementation specific improvements for ECL:
   merge with the ECL upstream version, support for the bytecode compiler.
  * Because it is required at least on ABCL, made the Unix vs Windows detection
   a runtime rather than compile-time distinction
   No more asdf-unix or asdf-windows feature, but
   (asdf::os-unix-p) and (asdf::os-windows-p) functions (not exported for now).
   Also recognize darwin as Unix ECL.
  * Also small improvements for SCL.

 Features:
  * Bind *default-pathname-defaults* around load-sysdef,
   to increase chances of successful pathname parsing in defsystem.
  * Fixed run-shell-command on allegro/unix and clisp,
   documented the function, noted how it mightn't do what you think on Windows,
   marked it as obsolete, promoted as an official replacement my new
       xcvb-driver:run-program/process-output-stream
  * New :around-compile hook so you can control the syntax, optimization,
   and warning level, rename packages and balance compile-time side-effects,
   etc., around the compilation of files in your own modules.
  * Now exporting function subpathname, to portably make subpathnames.

Happy Lisping!
