Version 1.8.1

This release introduces the following enhancements to support the HP-75:

• Added HP-75 text file import and export to the file management functions of the drive tab.
• Show HP-75 text files optional with or without line numbers from the context menu of the drive tab directory list
• Show keywords of HP-75 lex files from the context menu of the drive tab directory list

** Note:** This version of pyILPER now requires at least version 1.7.9 of the LIFUTILS.

Version 1.8.0

This release provides the following changes and extensions:

• Added the HP-2225B ThinkJet printer
• Added complete virtual terminal support for the HP-75 with a dedicated character set and keyboard layout and a HP-75 version of the PILTERM program which is provided on a new version of the PILIMAGE.DAT LIF image file.
• Next port key supported for the HP-71 keyboard emulation.
• Added local controls to the terminal tab to scroll up and down one page. This required minor changes to the HP-71 keyboard layout (see below).
• Various documentation amendments
• The most recent version of the PILTERM program is now 2.3
• The minimum required version for Python is now 3.5 instead of 3.4. Features of Python 3.5 and above make the code for calling external applications more clearly and easy to maintain.

Incompatibilities to previous pyILPER versions:

• Due to the introduction of the HP-75 character set the configuration of character sets in existing pyILPER installations must be adjusted if the Roman-8 character set was used.
• For the HP-71 terminal emulation the keystrokes for far left, far right, far up and far down are now shift left, shift right, shift up and shift down.
