We are announcing a bugfix ECL release that addresses a few issues that has slipped through testing of the recent one.

Addressed issues:

bugfix: MAKE-PACKAGE destructively modified defining form's cons cells of the package local nicknames, breaking package literals in bytecmp (#839)

I used an intentionally naïve numerical s...
