news/flnews: Update to 1.2.0

1.2.0  2023-06-08  Release
--------------------------

Important notes:
- The experimental option USE_CUSTOM_FONTSIZE has been removed
  Since FLTK 1.4 there is a resize feature via keyboard (Ctrl-+/-).
- Doxygen 1.9.4 is now required to build the documentation.

Bug fixes:
- GUI: Callback for "Mark all groups read" fixed to not block any
  further operation if confirmation was "No" (reported by Marcel Logen).
- GUI: Callback for "Next unread group" fixed to not always select the
  first group with unread articles (reported by Dennis Preiser).
- CONF: Update of configuration data fixed (formerly truncated if
  filesystem was full). Return values of flush operations are now
  checked before rename() is executed.
- GUI: Group list is now updated to previous group after group selection
  error (reported by Michael Uplawski).
- GUI: No longer show busy mouse cursor after group selection if article
  tree/list has no drawing area (reported by Michael Uplawski).
- ENC: Memory leak fixed in MIME Content-Disposition decoder.
- TLS: Memory leaks fixed.
- TLS: OpenSSL 3 version number is now printed correctly on terminal.
- GUI: Soft hyphens are now handled consistently with all FLTK backends
  (formerly X11 rendered all SHY characters visible, as defined by
  ISO 8859-1, while Pango and Cocoa rendered SHY characters invisible).
- FILTER: Documentation of scorefile syntax fixed (type "extended" is no
  longer supported).
- CORE: Doxygen documentation of function core_get_msgid() fixed.

New features and improvements:
- GUI: French translation added for NLS support (provided by yamo').
  NLS documentation updated for hexadecimal-escape-sequence (not
  allowed in translated strings).
- GUI: Option to skip to next group while searching for next unread
  article added (can be enabled with a nonzero value for the new
  "unread_in_next_group" entry in configfile) (proposed by Thomas
  Barghahn).
- GUI: No longer uses Fl_Pack widget because behaviour has changed in
  recent FLTK 1.4.0 snapshots (reported by Dennis Preiser).
- CONF: Support for custom colors in displayed article added
  (based on patch from Martin Schnitkemper).
- INET: Support for user defined TCP connection timeout (suggested by
  yamo'). Option CFG_TCP_CONNECT_TIMEOUT in CONFIG added.
- GUI: With FLTK 1.4 (or FLTK 1.3.3 ABI) the horizontal scrollbar of the
  article tree or list respectively is moved to a sensible position.
- CORE: Header field "Newsgroups" can now be extracted from overview, if
  present. Scoring rules of type "group" are applied to all groups of an
  Xpost in this case.
- NNTP: Support for LIST OVERVIEW.FMT command (RFC 3977) added.
- NNTP: Experimental support for MAXARTNUM extension added.
  Intended to be compliant with the RFC draft provided by Julien Élie
  in Message-ID <tnqm14$35bas$1@news.trigofacile.com>.
- ENC: Zero-width space (ZWSP) is now used too as line breaking hint for
  the format "flowed" decoder.
- GUI: URI delegation: Separate error message for invalid encoding.
- EXT: External URI handler returns a flag to indicate invalid encoding.
- EXT: Examples for postprocessor added in subdirectory "postproc"
  (suggested by yamo').
- EXT: Example for external editor added in subdirectory "editor".
- CONF: Documentation of configfile entry "cancelkey" modified (added
  note that "fqdn" entry must also be set to create Cancel-Lock/Key
  header fields).
- FILTER: Documentation of scorefile modified (added notes that scoring
  rules can be shared).
- Build system: The mkconfig script now checks for POSIX.1c-1995
  Thread-Safe Functions (TSF) option too. Usage is forced by default via
  CFG_FORCE_TSF option in CONFIG.
- Build system: The C++ object files are moved to the beginning of the
  list. This can reduce build time with make utilities that support
  parallel build.
- Build system: BSD install utility now deletes existing target files
  before copying new ones. This solves problems with macOS on machines
  with Apple Silicon and signed binaries (patch from Dennis Preiser).
- Unicode database updated to version 15.0.0
