Enclosed are the release notes for MacTCP 1.1.1. John Veizades... Apple Computer, Inc. Senior Engineer, MacTCP Team ----------------------------------------------------------------------- Release Notes for MacTCP v1.1.1 Copyright )1992, Apple Computer, Inc. All rights reserved. August 14, 1992 MacTCP v1.1.1 is an update release for MacTCP v1.1. It includes the following improvements: - The number of recognized host file entries is significantly increased. - When an AddrToStr procedure is called with a string of size 16 char and a full IP address (an IP address containing all 3 digit numbers such as 123.123.123.123), an extra byte is no longer overwritten. - When used over AppleTalk Remote Access, MacTCP handles AppleTalk transition events properly. - DNR does not leak memory. - ARP responses are returned for 802.3 ARP requests. - ICMP echo requests no longer crash 68000-based Macintosh computers. - TCP connections are maintained over slow speed or long delay connection paths. - UDP Multiport Read returns the correct values for the destination port and address. - CMU BootP compatibility is supported. - On links of a transitory nature such as SLIP and PPP, MacTCP initializes correctly by resending BootP requests on the open transition event from the LAP. - The UDP ASR routine in UDPMultiPortCreate is no longer overwritten. - Performance on Mac Plus computers running System 7.0.x is increased. - TCPSend works correctly on AppleTalk connections to sites that have disappeared and reappeared on the network. - The MacTCP control panel shows all available AppleTalk link icons. - Packets are no longer dropped when time to live equals 1. - Pre-AppleTalk Phase 2 Ethernet drivers are supported. IN ADDITION: - For server based addressing, when switching between data links in the MacTCP control panel, set the default gateway address to 0.0.0.0 to assure that the gateway address is subsequently obtained correctly. - In low memory situations, high traffic, high transmission rate connections can experience data loss problems. These problems can be avoided if applications give MacTCP enough memory to work correctly. Application developers should be sure to consider the following when making memory calculations: - Network MTU size affects the amount of memory needed to receive fragmented datagrams. Assume that fragmented packets may be received. - An application's packet usage may vary from typical expectations. For instance, although telnet applications are mostly used in character operations, some applications send full size datagrams to telnet consoles. Such usage may break connections if applications don't allocate enough memory for MacTCP. .
