A plain-text, printer-friendly version of these pages can be found at Caveats.txt

1. Support for long, float, and double primitive types (Long, Float, and Double classes as well)
2. There is currently no support for trigonometric and most other methods in the java.lang.Math class.
3. Multi dimensional arrays implemented
4. checkcast and instanceof work in all cases
5. System.exit(int) implemented
6. New Java I/O Support Memory mapped I/O using any chipselect and address offset. I2C using port pins P5.0 and P5.1 (C0TX and C0RX, pins 8 and 9 on 68 pin SIMM) I2C using any two memory mapped latches. Access to the available port pins on the processor (P3.0 - P3.5 and P5.0 - P5.3) BE CAREFUL WITH THESE, YOU CAN RESET THE SMC CHIP AND CAUSE MAJOR DEATH AND DESTRUCTION WITH THESE PINS! KNOW WHAT YOU ARE DOING BEFORE HACKING.
7. DNS and DHCP support
8. The FTP Server now accepts mixed case commands for FTP clients that need this.
9. com.dalsemi.nethack.EthernetAccess class has been deprecated. Look at the com.dalsemi.tininet.TININet class for the same functionality. Any deprecated classes will be removed before the final release.
10. Java URL class support (http:, ftp:, mailto:, file:)
11. TMEX iButton communication layer added to API
12. Minor Java Virtual Machine speedups
13. Minor memory management speedups
14. Updated tini.jar
15. Updated JavaKit
16. i2ctest - Simple example on how to use the I2C interface with port pins or memory mapped latches. Talks to DS1621 temperature sensor at address 0x90.
17. 19200 bps version of JavaKit now available

1. FTP SERVER The FTP server now accepts case insensitive commands for FTP clients that need this.
2. FILE OWNERSHIP AND PERMISSIONS Files now have an owner name associated with them. If you execute the command 'ls -l' you will see a screen similiar to:

           -rwx--- root        673 09-13-99 16:40  index.html
           -rwx--- root        186 09-13-99 16:42  web.log
           -rwx--- root        531 09-13-99 16:39  EchoServer.tini
           -rwx--- root       4186 09-13-99 16:40  TINIWebServer.tini
           drwxr-x root          3 00-00-00 00:00  etc
   

   The permissions for etc, from left to right, indicate directory(d), owner-read(r), owner-write(w), owner-execute(x), world-read(r), NOT-world-write(-) and world-execute(x). Permissions are associated with each user account.
