	PICOTRON VERSION HISTORY
--------------------------------------------------------------------------------------------

	0.1.0g

		Added: pause menu for fullscreen programs (ENTER -> continue, toggle sound, reset cartridge, exit)
		Added: file extension associations. To specify a default app: default_app vgfx /apps/tools/veditor.p64
		Added: shortcuts: ctrl-home, ctrl-end in code/text editor;  ctrl-a (home) and ctrl-d (delete) in terminal
		Changed: .sfx format and resource loader now stores 256k by default (space for 398 SFX; is backwards compatible)
		Changed: Open File and New File (via app menu) always open in the program that requested it (ref: VisiTrack, VGFX)
		Changed: Can not rename a file over an existing filename in filenav
		Fixed: sometimes boot into an invalid workspace and need to switch back and forth to mend
		Fixed: web player: audio, key(), touch controls (but only P8 buttons for now)

		Fixed: stray globals in terminal: k, res, cproj_draw, cproj_update
		Fixed: node output missing in instrument designer
		Fixed: crash when blit()ing from outside of source bitmap // was happan when using magnifying glass at bottom right
		Fixed: magnifying glass drawing black as transparent
		Fixed: btn(), btnp() when no _update() callback exists only works via ctrl-r and not when run directly from desktop / terminal
		Fixed: several types of crackles / discontinuities in audio mixer, mostly relating to echo nodes
		Fixed: SFXs 64 and above are not initialised to "empty" (instead, zeroed data that shows up as C0's)
		Fixed: some ctrl- combinations produce a textinput event. e.g. ctrl-1 // explicitly blocked in events.lua
		Fixed: (Mac) icon is slightly too big
		Fixed: (Mac) Option key not mapped to "alt"
		Fixed: cursor in terminal doesn't wrap with command string
		Fixed: Locked mouse speed is different along X & Y (partial fix)

	0.1.0f

		Added: reboot
		Added: logged disk writes for backups / versioning ("anywhen" in settings)
		Added: load cart.p64@2024-04-06_14:00:00 to load a cart from the past (or just @14:00 for short if same day -- local time)

		Added: stat(87) for timezone delta in seconds (add to local time to get UTC)
		Added: drag and drop host files into picotron (copied to /ram/drop -- not mounted) -> generates a "drop_items" message
		Added: drop a png into gfx editor to load it (colour fits to current display palette)
		Added: filenav: open files or folder on host via app menu ("View in Host OS")
		Added: can fetch .p64 host files directly as binary strings // same semantics as fetching "https://...foo.p64"		
		Added: PICO-8 style string indexing;  ?("abcde")[4] --> "d"    ?("abcde")[02] --> nil
		Added: btnp() repeat rates (follows PICO-8: initial repeat delay: @5f5c, subsequent delays at @5f5d specified at 30fps)

		Fixed: trailing slash for folders on tab complete in filenav, terminal
		Fixed: delete key + AltGr not working in terminal

		Fixed: tracker knobs hard to use when close to edge of the screen (now using mouselock and finer sensitivity)
		Fixed: using keyboard controls while a game controller is plugged in causes ghost button presses
		Fixed: ceil(1.0) returns 2 ._.

		Fixed: redundant cartridge file flushing (writes that happen within 300ms are now batched)
		Fixed: search for an empty spot on desktop to create dropped files
		Fixed: key() / keyp() returns false when received keyup and keydown messages in same frame (should be true for 1 frame)

		Changed: gui elements must explicitly :set_keyboard_focus(true) on click to consume textinput events
		Changed: screenshots and untitled cart filenames are given an integer suffix to reduce collisions 
		Changed: when saving a file with no extension, wrangler automatically adds the default filename extension
		Changed: track (sfx) length can be specified pico-8 style by increasing loop0 (memory layout doesn't change)
		Fixed: load #bbs_id twice over the same local file -> fails to unmount the first cartridge
		Fixed: audio lock causing random crashes on Mac (tentative ~ not sure if that was the cause or the only cause)

		Fixed: flashing when windowed cartridge runs at < 60fps with a custom display palette (e.g. inst editor)
		Fixed: flashing when video mode 3 or 4 running at < 60fps
		Fixed: filenav selects .loc files (drive.loc) as target to save over instead of opening it like a folder
