Version 1.16

• Show prio of processes with threads with different prio as !be/4
• Show threads under their process
• Add a gap between pseudo-graph and command to visually group threads of the same process
• Aggregate all thread data in their process
• Edit pid/user filters from interactive mode
• Scrolling for the main view by UP/DOWN/PGUP/PGDN
• Let 0 show all columns

Version 1.15

- fix read return value converted to unsugned (and possible OOB in the rare case that happens
- fix keypress ignored during screen refresh
- fix Ctrl-L to really redraw screen

Version 1.14

• fix off-by-one errors in size calculation to avoid truncated strings
• unify snprintf usage according to glibc semantics
• keep both variants of cmdline in memory for immediate display change (hotkey c)
• rewrite get_vm_counters with simpler io
• nuke the remnants of -s/--iohistory options
• be more strict to unrecognized arguments

Version 1.12

- fix SIGSEGV in humanize_val on large values
- convert the pseudo-graph to a normal column
- remove option -s (replaced by -8 with inverse logic)
- add sort by the pseudo-graph column
- make sort by the pseudo-graph the default
- implement hiding columns by options and shortcuts 1...9
- revise column widths
- rewrite curses event loop to make data collection separate from refresh
- fix sorting (proper double value comparison)

Version 1.11 - make graphs scale with screen size

- better detection of locale/terminal
- add graph and UTF/ASCII toggles to help
- increase history to 60 datapoints
- make graphs scale as screen size changes
- always keep track of history data (graph display toggle no longer affects the data collected)
- use the history data as 'only' filter in interactive mode

Version 1.10 - improve UTF detection for text pseudo graphs

Version 1.10 - improve UTF detection for text pseudo graphs
- add pseudo graphs for total IO activity
- add detection of UTF support, fallback to ASCII
- add shortcut to toggle UTF/ASCII
- improve build checks for printf-like ncurses API

Version 1.9 - show IO history data as text pseudo-graph

v1.9

Update README.md

Version 1.8 - miscellaneous cosmetic fixes

• license header per file w/SPDX tag
• reduce local variable scope where possible
• add checks for passing NULL to %s (silence warnings)
• use the canonical GPLv2 license file
• spelling

Version 1.7 - implement unicode support

This release implements full unicode support for strings coming from outside (command line and user name); they are processed to remove non-printing chars, cell length is determined by each character's width on a terminal and then trimmed/padded to the appropriate cell.
