  • On OpenBSD: restrict system operations by using pledge() if it's available.
  • Window scrolling capabilities!

Changed

  • /msg: fail if recipient is ChanServ or NickServ. (Use of the commands /chanserv and /nickserv should be considered instead.)
  • Interpreter: handle string truncation when copying an identifier or argument
  • Look of the output produced by /list
  • Only call unget_wch(MY_KEY_RESIZE) after sleeping for a requested interval. This possibly prevents the program from crashing or the terminal from being hung up due to a "resize attack".

    • 471-474
    • 481 (ERR_NOPRIVILEGES)
    • 742 (MODE cannot be set due to channel having an active MLOCK restriction policy). ATM not documented in the RFC.

Changed

  • The default theme. Color codes that consisted of only one digit were changed to use two digits in some cases. For example: ^C3 changed to ^C03, ^C5 changed to ^C05, etc. Why? Consider a function call like printtext(..., "%sone or more digits", Theme(primary_color)). If the primary color, in this case, consists of only one digit and is directly followed by one or more digits the result is: one digit is lost and a random color will be displayed.

Fixed

  • As a fallback, instead of printing out "Printtext Internal Error", continue to convert characters even if some are lost due to an invalid multibyte sequence.
  • Interpretation of color codes in the printtext module. For example: ^C123 didn't display '3' before as it should.
