-0.1.6
+0.2.0
 #First line must be a semantic version number
 #all other lines are ignored.
+#0.2.0 - codethread init_script now propagates package prefer via %packageprefer% scriptmap entry
+#0.2.0 - code interp (punk/0 repltype) now uses punk::lib::interp_sync_package_paths -libunknown 1 instead of manual epoch-only copy, propagating tm list, auto_path, package prefer, and libunknown to the code interp
 #0.1.6 - repl::init routes default console construction through punk::console::default_console (also gains the probe-byte store unification)
 #0.1.5 - repl::init comment updated: ambiguous capability settles at first console use via punk::console::settle_can_respond (no behaviour change)
 #0.1.4 - repl::init constructs the process-default console object (opunk::console instance: default) and settles can_respond 1 for interactive stdin (negative settle deliberately not done at init - see comment)
