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