Luatex 1.15.0 announcement.

[luigi scarso]

[-- Attachment #1.1: Type: text/plain, Size: 506 bytes --]

==============================================================
LuaTeX 1.15.0 2021-12-31
==============================================================

New primitive \matheqdirmode.
By default the short skip detection is not adapted to r2l typesetting and
that
hasn't been the case since the start of the project. Changing it could break
hacks that users came up with but when you set \matheqdirmode to a positive
value direction will be taken into account.

Several bug fixes (see ChangeLog).

[NTG-context] Luatex 1.17.0 announcement.

[luigi scarso via ntg-context]

[-- Attachment #1.1: Type: text/plain, Size: 1023 bytes --]

(Sorry for the delay, I wanted to be sure that building phase was over)

==============================================================
LuaTeX 1.17.0 2023-04-29
==============================================================

- A breaking backward compatibility change: by default the socket
  library is not enabled .
  The new option --socket enable the socket library as
  before, as also --shell-escape (without --shell-restricted);
  --nosocket, --no-socket , --safer disabled the library, and
  they have the priority in case of conflicting options.
  The mime library is always available; socket.sleep
  and socket.gettime are duplicated as os.socketsleep
  and os.socketgettime, both always available.
  The new os.kpsepopen replace io.popopen in kpse mode
  (i.e. when kpse_init is not zero) as it was before
  but the permission now cannot be changed anymore with
  kpse.check_permission .
  The function os.kpsepopen follows the same restrictions
  as io.popen .
  Thanks to Max Chernoff for debugging.
