• Fixed: Client crash when placing server racks at y-level 0/255.
• Fixed: Hover upgrades being installable in devices where they made no sense.

Patch 1.5.9

• Added: Charger can now be used to charge battery upgrades, as well as other energy items (e.g. RF or EU powered items).
• Added: The experience upgrade can now consume enchanted items and XP bottles for experience.
• Added: Integration with IngameWikiMod (made most pages from OC's manual available in it).

• Added: Support for BluePower's bundled redstone.
• Added: Support for more GregTech machines in recipe definitions.
• Added: Waypoint block, can be queried using navigation upgrades.
• Changed: Reworked logic for rendering upgrades on robots. Makes it easier for addons to render their upgrades, and makes it work in MC 1.8 again.
• Fixed: Drones losing their name when changing their EEPROM.
• Fixed: Potential client-side log spam in disassembler GUI when disassembleAllTheThings was enabled.
• Fixed: Robot animations continuing when game was paused.
• Fixed: Robot rendering potentially leaving OpenGL state in a way that leads to certain blocks to not be rendered.
• Fixed [MC1.8]: A few potential NPEs.

Patch 1.5.8

• Added: Emitting particle effects from robots when they try to move but fail. Added small timeout to avoid particle spam, so using detect instead of just trying to move may be more efficient, now.
• Added: Peaceful-friendly recipe file (thanks dgelessus).
• Added: Russian translation for manual (thanks a lot cyber01).
• Changed: Allow redrawing holograms a tad faster, added method for setting raw data for fast full data swaps.
• Fixed: A few issues with drones moving through portals, in particular they won't power down after moving through one, anymore.
• Fixed: Absolute paths in manual (noticeable in the links from the German index to the English one not working).
• Fixed: OpenOS being listed twice in creative tab/NEI.
• Fixed: Potential memory leak involving drones.
• Fixed: Race condition in computers that could lead to them stopping randomly.
• Fixed: Reduced memory use of timeout enforcing logic in __gc callbacks.
• Fixed: Standard I/O streams being closable in OpenOS (thanks mpmxyz).
• Fixed: When using LuaJ fallback, computers were not starting when loaded again, when unloaded while running.
• Fixed [MC1.8]: Colored text on screens influencing color of other rendered stuff.
• Fixed [MC1.8]: Piston upgrade.

Patch 1.5.7 - Document All The Things

• Added: Allow specifying level of redstone signal emitted by prints.
• Added: Tab completion in Lua interpreter.
• Added: Prints can now emit light.
• Added: Allow using dyes as ink input for printers, much less efficient than using cartridges.
• Added: Ingame documentation via book. Contains documentation on pretty much everything in the mod.
• Added: A wrench. Mostly for MC1.8. But it should be compatible with most other mods, too.
• Changed: Using manual in recipe for Lua BIOS and OpenOS now.
• Changed: Made speed of gpu.setPaletteColor depend on GPU tier and made it a lot faster.
• Fixed: Potential crash when trying to render a char that could not be generated.
• Fixed: Chamelium blocks being registered breaking mipmaps.

Patch 1.5.6

• Added: Chamelium is now edible. But don't.
• Added: More AE2 integration (thanks DrummerMC).
• Changed: Floppies and hard drives can no longer be wiped by shift right-clicking them. To wipe loot floppies, craft them on their own (i.e. put them in a crafting grid).
• Changed: Improved recipe handling. Recipes can now be disabled by assigning false to them. Missing recipes will generate a warning.
• Fixed: 3D Print info in WAILA.
• Fixed: Converter for Forestry now not only applied for bees in Analyze/Bee House/... but also for bees in inventories.
• Fixed: Disassembler ignoring recipe output sizes (leading to fun effects like iron nuggets being disassemblable into iron ingots).
• Fixed: Potential crashes in AE2 integration even when used with newer AE2 versions. Hopefully.
• Fixed: Prints now properly register themselves for FMP slots, making them work as covers for Project Red cables, for example.
• Fixed: Redstone I/O block properly wakes computers now.
• Fixed: Wireless messages potentially triggering chunk loads.

Patch 1.5.5

• Added: 3D prints can be recycled by putting them into 3D printers as material.
• Added: Sign upgrade will add sign text to tablet_use signal.
• Added: Filtering to AE2 item listing callbacks getItemsInNetwork and getCraftables. Filters are tables with the same (basic) keys as converted item stacks, the values being the (exact) filter values.
• Added: Drivers for newer RF energy API interfaces, should make them work with mods only implementing the newer ones.
• Added: Lore entry is now added to item stack information.
• Fixed: Potential memory leak with Microcontrollers (thanks a ton to marcin212).
• Fixed: cat.lua not closing file handles (thanks mpmxyz).
• Fixed: Mod integration for power providing mods being disabled when power usage was disabled.
• Fixed: Potential persistence issues with userdata.
• Fixed: Improved persistence behavior of TCP sockets.
• [MC1.7.10] Fixed: UV mapping for 3D prints.
• [MC1.7.10] Fixed: hopefully fixes crashes with AE2 version rv2-beta-20 and newer.

Edit: Build 11 is a hotfix for a crash in the power distributor tile entity renderer.
