Hi,

Unbound 1.13.0rc4 pre-release is available:
https://nlnetlabs.nl/downloads/unbound/unbound-1.13.0rc4.tar.gz
sha256 b7cfb0fe0f138970271d9e037913350a0ca03a66ead6e6f77cc0ca02f7245aa3
pgp https://nlnetlabs.nl/downloads/unbound/unbound-1.13.0rc4.tar.gz.asc

This RC4 fixes a bug that was reported on the RC3 candidate, an
assertion failure for upstream TLS and a double callback.

Bug Fixes
- Fix assertion failure on double callback when iterator loses
  interest in query at head of line that then has the tcp stream
  not kept for reuse.

Best regards, Wouter
