Orchard 0.8

Changes

• Remove dynapath dependency
  • With it, defns related with mutable classloader are now deprecated and are no-ops
  • -Dorchard.use-dynapath=false has no effect now either.
• Accomodate enrich-classpath
  • Now, if you intend to use Orchard for its Java functionality, it is expected that you use enrich-classpath also.
  • If not present, Java-related features won't work (but at least won't throw a compile-time error).

Bugs Fixed

• #135: Fix problematic double var lookup in orchard.xref/fn-refs.
