000089 Added More informations in error messages of unexpected errors.
000087 Changed The vi ZB.rtc.timedate.set.vi  has been synchronised with the seconds information of the rtc. This behaviour semms no longer needed. The vi had a execution time of up to 1s. Care must be taken‚ because the time information wont be adjusted and the old information will be read out until the next second.
000086 Changed The vi ZB.rtc.timedate.set.vi passes the weekday information to the mid layer. Not all kinds of RTCs store the weekday information. This change only takes affect for external rtcs that accept variable weekday information.
000080 Added New version Information Tool
(Can be started from Kick starter)
00007F Added Version Numbers harmonised:
Generation.Release.Zwischenversion-LabVIEW Version
Bsp: 3.1.5-86

000068 Added Function ZB.lcd.close.vi added.
The LCD on the ZMC needs a specified shut down sequence. Otherwise a white screen can occure at when restarted without a complete power cycle.
000067 Added ZB.timer.getdutycyle.vi wrong function call in compiled mode
000064 Added The update speed of the display has been increased (doubled)

000057 Fixed The touch driver for ad7877 got improvements to prevent from hanging target in some application set ups.
000056 Fixed Removing a event from a DIN did not remove the edge sensitive behaviour.
When a event is set on a DIN‚ the DI cannot be polled. With this fix‚ the DIN can be polled again when the event is removed.
000055 Fixed ZB.touch.removeall.vi wrote to wrong memory area. Causing unexpecetd behavior.
000054 Changed Timers controlled by ZB.timer.*.vi s are new halted on emulator halt.
000053 Added Support for Displsys driven via 16 bit ppi. this can reduce target costs for custom targets.
000052 Changed Driver level errors from ZB.lcd.showbmp.vi were generated for component "files" rather than "lcd"
00004D Added Some targets can be putted in Mass Storage device mode. In this mode‚ they can be connected to the PC to get direct access to the storage media. This mode can be reached from FDM mode only.
A new example (Storage) enables the ZMC to be connected to a PC via USB as Mass Storage Device to browse the files on the SD Card.
00004C Added New simple graphic primitive Vis
ZB.lcd.draw.line.vi and
00004B Fixed ZB.lcd.showbmp.vi. Bitmaps were displayed distordet depending on the width of the bitmap.
000049 Fixed When enabling TCP/IP Support the following Linker error may occure:
[Error li1030]  Can not open input file 'lv_lwip_z_catagna.dlb'.
Beta Catagna can be patched with Zbrain BSP patch catagna LWIP to enable TCP/IP functionnality.
000048 Added New component TWI (2-wire interface).
These VIs allow a Z-hardware to interface to external components via an Inter IC bus as specified by the Philips I2C Bus Specification‚ version 2.1‚ dated January 2000.
000042 Changed ADC drivers share code for buffer handling. Changings in the behaviour are not expected.
000040 Added New exernal component AD799X. (AD7991 AD 7995 and AD 7999)
ADC with 4 channels and 8‚ 10 or 12 bit resolution on the TWI interface.
00003D Added The new vi ZRefMnC.hibernate.vi sets the processor in hibernate mode.
This is the most power saving mode. The processor stops working. One of 6 interrupt sources can wake up the processor by executing a reset.
00003C Added ZRefMnC.power.v_module.vi is new able to set the SMSC Ethernet chip in power saving mode.

Issues that are not listed here have no obvious afect on the behaviour of a embedded application or are only relevant on targets other than ZMC.
