Release 1.12.86

[1.12.86] - 2026-04-01

Enhancements

• #10: Allow : and ; as load path
  separator on Linux and MacOS. On Windows ; is supported only due to the
  Windows' convention for absolute paths C:\users\foo.

• #11: Support Hybrid Encryption for
  remote REPL communication to achieve TLS/SSH grade security.

  • Level 0: Client authentication through principal/password, no encryption, no signing
  • Level 1: Client authentication from Level 0 with symmetric AES-256 GCM message
    encryption through symmetric session keys generated by Diffie-Hellman key exchange
  • Level 2: Hybrid encryption by signing the Diffie-Hellman key exchange with RSA
    asymmetric keys, thus preventing Man-in-the-Middle attacks. Messages are
    AES-256 GCM encrypted through symmetric session keys generated by Diffie-Hellman
    key exchange

  Note: Hybrid encryption can also be achieved by tunneling a Level 0 type remote
  REPL communication through an accordingly configured SSH tunnel.

Bugs

• Fixed a nasty Github CI unit test problem on the Ubuntu platform. Github CI
  Ubuntu silently changed to a Dash Shell when using the /bin/sh link, causing
  some test scripts with Bourne Shell syntax to fail. Switched to /bin/bash in
  the affected unit tests.
