513 It looks like this might be the last release before 1.0.
516 version 1.0pre4 Jan 17 2001
518 * Updated documentation; the documentation now reflects the
519 configuration as it is.
521 * Some internal changes to make tinc scale better for large
522 networks, such as using AVL trees instead of linked lists for the
525 * RSA keys can be stored in separate files if needed. See the
526 documentation for more information.
528 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
532 version 1.0pre3 Oct 31 2000
534 * The protocol has been redesigned, and although some details are
535 still under discussion, this is secure. Care has been taken to
536 resist most, if not all, attacks.
538 * Unfortunately this protocol is not compatible with earlier versions,
539 nor are earlier versions compatible with this version. Because the
540 older protocol has huge security flaws, we feel that not
541 implementing backwards compatibility is justified.
543 * Some data about the protocol:
545 * It uses public/private RSA keys for authentication (this is the
546 actual fix for the security hole).
548 * All cryptographic functions have been taken out of tinc, instead
549 it uses the OpenSSL library functions.
551 * Offers support for multiple subnets per tinc daemon.
553 * New is also the support for the universal tun/tap device. This
554 means better portability to FreeBSD and Solaris.
556 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
558 * tinc now uses the OpenSSL library for cryptographic operations.
559 More information on getting and installing OpenSSL is in the manual.
560 This also means that the GMP library is no longer required.
562 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
563 Carrasco provided us with a Spanish translation of the manual.
566 What still needs to be done before 1.0:
568 * Documentation. Especially since the protocol has changed, and a lot
569 of configuration directives have been added.
574 version 1.0pre2 May 31 2000
576 * This version has been internationalized; and a Dutch translation has
579 * Two configuration variables have been added:
580 * VpnMask - the IP network mask for the entire VPN, not just our
581 subnet (as given by MyVirtualIP). The Redhat and Debian packages
582 use this variable in their system startup scripts, but it is
584 * Hostnames - if set to `yes', look up the names of IP addresses
585 trying to connect to us. Default set to `no', to prevent lockups
588 * The system startup scripts for Debian and Redhat use
589 /etc/tinc/nets.boot to find out which networks need to be started
592 * Fixes to prevent denial of service attacks by sending random data
593 after connecting (and even when the connection has been established),
594 either random garbage or just nonsensical protocol fields.
596 * tinc will retry to connect upon startup, does not quit if it doesn't
599 * Hosts that are disconnected implicitly if we lose a connection get
600 deleted from the internal list, to prevent hogging eachother with
601 add and delete requests when the connection is restored.
604 What still needs to be done before 1.0:
607 * Failover ConnectTo lines, try another one if the first doesn't work.
