"Prosody 0.10.2 ==============

See upstream's blog post at
https://blog.prosody.im/prosody-0-10-2-security-release/ for a full
overview of the release changes.

Prosody 0.10.2 fixes a cross-host authentication vulnerability,
CVE-2018-10847. The issue affects Prosody instances that have multiple
virtual hosts (including anonymous authenticated hosts). All versions
of Prosody before 0.9.14 and 0.10.2 are affected. A full security
advisory is available at https://prosody.im/security/advisory_20180531

Security

--------

  - mod_c2s: Do not allow the stream ‘to’ to
    change across stream restarts (fixes #1147)

Minor changes

-------------

  - mod_websocket: Store the request object on the session
    for use by other modules (fixes #1153)

  - mod_c2s: Avoid concatenating potential nil value (fixes
    #753)

  - core.certmanager: Allow all non-whitespace in service
    name (fixes #1019)

  - mod_disco: Skip code specific to disco on user accounts
    (avoids invoking usermanager, fixes #1150)

  - mod_bosh: Store the normalized hostname on session
    (fixes #1151)

  - MUC: Fix error logged when no persistent rooms present
    (fixes #1154)

Dowstream

  - Changed log rotation from weekly/52 to local system
    defaults
