2017-10-19 (thetaepsilon)
Directional flowables are now implemented.
All devices for which it is relevant (valve, flow sensor etc.) have been converted so that they only flow on their connecting sides, so pressure propogation now works as expected for these devices when pressure logic is enabled.
Classic mode continues to be preserved by default as before.



2017-10-14 (thetaepsilon, VanessaE)
Node breakers have been updated to not have a tool by default, and determine if the node that they are trying to break can be dug with the tool in it's inventory slot.
The crafting recipe for the node breakers has been updated, using a new gear crafting item that requires iron instead of mese, which should be a more accessible cost in most cases.
Existing node breakers in worlds will get their mese pick back if their slot is empty via LBM - the mese pick will show up in the inventory slot so you can reclaim your hard-earned mese crystals.
Gear item texture and updated node breaker textures provided by VanessaE.



2017-10-08 (thetaepsilon)
A lot more of the new flow logic work.
There are two sub-modes of this now,  non-finite and finite mode.
Non-finite mode most closely resembles "classic mode", whereas finite mode is more intended for use with mods such as dynamic_liquids which enable water sources to move themselves.
Everything that was functional in classic mode more or less works correctly now.
Still TODO:
+ Flow directionality - things like flow sensors and airtight panels will flow in directions that don't make sense from their visuals.
Possible feature requests:
+ Making tanks and gratings do something useful.



2017-09-27 (thetaepsilon)
Start of new flow logic re-implementation.
This mode is current *very* incomplete, and requires a per-world setting to enable.
Adds a pressure value stored in all pipe node metadata, and a mechanism to balance it out with nearby nodes on ABM trigger.
Currently, this inhibits the old behaviour when enabled, and (again WHEN ENABLED) breaks pretty much everything but normal pipes, spigots and pumps.
For this reason it is far from being intended as the default for some time to come yet.
What *does* work:
+ Pumps will try to take in water (and removes it!) as long as internal pressure does not exceed a threshold.
	- a TODO is to make this pressure threshold configurable.
+ Pipes will balance this pressure between themselves, and will slowly average out over time.
+ Spigots will try to make the node beneath them a water source if the pressure is great enough and the existing node is flowing water or air.
	- This is admittedly of fairly limited use with default water mechanics; those looking for more realistic mechanics might want to look at the dynamic_liquid mod, though that mod comes with it's own caveats (most notably drastic changes to previous worlds...).
What *does not* work:
+ Flow sensors, valves. Valves in particular currently do not function as a barrier to water's path under the experimental logic.
	- TODO: internal code to allow this to be overriden.



*seems this hasn't been updated in a while*

2013-01-13: Tubes can transport items now! Namely, I added Novatux/Nore's item 
transport mod as a default part of this mod, to make tubes do something useful!
Thanks to Nore and RealBadAngel for the code contributions!

2013-01-05: made storage tanks connect from top/bottom, made storage tank and 
pipe textures use the ^ combine operator so they can show the actual liquid 
going through the pipes/tanks.

2013-01-04 (a bit later): Made pipes able to carry water! It was just a minor 
logic error resulting from moving the water flowing code into it's own file 
when I originally imported it.  Many thanks to Mauvebic for writing it!

2013-01-04: First stage of integrating Mauvebic's water flowing code.  This is 
experimental and doesn't move water yet - but at least it doesn't break 
anything :-)

2013-01-01: Various minor tweaks to textures, facedir settings, some other 
stuff.  Changed crafting recipes to account for revamped pumps, valves, etc.  
Now requires the moreores mod and most recent git (for mese crystal fragments) 
to craft a pump.  Added a "sealed" entry/exit panel (really just a horizontal 
pipe with a metal panel overlayed into the middle).  Also, tweaked pipes to 
always drop the empty ones.  Revamped pumps so that now they should sit in/on 
liquid and be connected only from the top, relegated grates to decorational- 
only, added outlet spigot.  Got rid of a few obsolete textures.  Got rid of 
that whole _x and _z naming thing - now all directional devices (pumps, valves, 
spigots, tanks) use facedir.  Valves, spigots no longer auto-rotate to find 
nearby pipes.

2012-09-17: Added test object for pneumatic tube autorouting code, made tubes 
connect to it and any object that bears groups={tubedevice=1} (connects to any 
side)

2012-09-05: All recipes doubled except for junglegrass -> plastic sheet (since 
that is derived from home decor)

2012-09-02: Fixed plastic sheeting recipe.  Added crafting recipes for various 
objects, with options: If homedecor is installed, use the plastic sheeting 
therein.  If not, we define it manually.  If the Technic mod is installed, 
don't define any recipes at all.  Also removed the extra "loaded!" messages and 
tweaked the default pipe alias to point to something that is actually visible 
:-)

2012-09-01:  flattened wielded pipe segment.

2012-08-24: Added square-ish pneumatic tubes with their own autoplace code 
(does not connect to steel pipes or pipe-oriented devices), then revised their 
textures shortly after.  Fixed a recursion bug that sometimes caused a stack 
overflow.  Old pipes were overriding the pipeworks:pipe defintion that belongs 
with the new pipes.

2012-08-22: Added outlet grate, made it participate in autoplace algorithm.  
Extended storage tank to show fill level in 10% steps (0% to 100%).  Added 
"expansion tank" that appears if the user stacks tanks upwards.  (Downwards is 
not checked).

2012-08-21: Made storage tank participate in autoplace algorithm.  Tuned API a 
little to allow for more flexible placement.  Re-organized code a bit to allow 
for some upcoming rules changes.  Made storage tanks' upper/lower fittins and 
intake grate participate in autoplace algorithm.

2012-08-20: Added temporary nodes for storage tank and intake grating, but 
without autoplace.

2012-08-19: Pumps and valves now fully participate in the 
auto-rotate/auto-place algorithm.

2012-08-18: Total rewrite again.  All pipes are now nice and round-looking, and 
they auto-connect!  Also added temporary nodes for pump and valve (each with an 
on/off setting - punch to change).  No crafting recipes yet and the pipes still 
don't do anything useful yet.  Soon.

2012-08-06:  Moved this changelog off the forum post and into a separate file.

2012-08-05 (multiple updates): Rewrote pipeworks to use loops and tables to 
create the nodes. Requires far less code now. Added -X, +X, -Y, +Y, -Z, +Z 
capped stubs and a short centered horizontal segment. Changed node definitions 
so that the aforementioned "short centered" segment is given on dig/drop.  
Renamed it to just "pipeworks:pipe" (and pipe_loaded). Added empty/loaded 
indicator images to the capped ends, removed some redundant comments. Made the 
empty/loaded indication at the capped end more prominent.

2012-07-21: Added screenshot showing pipes as they look now that nodebox 
texture rotation is fixed.

2012-07-18: Changed the mod name and all internals to 'pipeworks' instead of 
'pipes'... after a couple of mistakes :-)

2012-07-12: moved project to github.

2012-06-23: Initial release, followed by reworking the textures a bit.
