Upgrading:

  lei users need to "lei daemon-kill" after installation to load
  new code.  Normal daemons (read-only, and public-inbox-watch)
  will also need restarts, of course, but there's no
  backwards-incompatible data format changes so rolling back to
  older versions is harmless.

Major bugfixes:

  * lei no longer freezes from inotify/EVFILT_VNODE handling,
    user interrupts (Ctrl-C), nor excessive errors/warnings

  * IMAP server fairness improved to avoid excessive blob prefetch

New features:

  * POP3 server support added, use either public-inbox-pop3d or
    the new public-inbox-netd superserver

  * public-inbox-netd superserver supporting any combination of HTTP,
    IMAP, POP3, and NNTP services; simplifying management and allowing
    more sharing of memory used for various data structures.

  * public-inbox-httpd and -netd support per-listener .psgi files

  * SIGHUP reloads TLS certs and keys in addition to config and .psgi files

  * "lei reindex" command for lei users to update personal index
    in ~/.local/share/lei/store for search improvements below:

Search improvements:

  These will require --reindex with public-inbox-index and/or
  public-inbox-extindex for public inboxes.

  * patchid: prefix search support added to WWW and lei for
    "git patch-id --stable" support

  * text inside base-85 binary patches are no longer indexed
    to avoid false positives

  * for lei users, "lei reindex" now exists and is required
    to take advantage of aforementioned indexing changes

Performance improvements:

  * IMAP server startup is faster with many mailboxes when using
    "public-inbox-extindex --all"

  * NNTP group listings are also faster with many inboxes when
    using "public-inbox-extindex --all"

  * various small opcode and memory usage reductions
