FreeBSD 5.0 Developer Preview 1 jest już dostępne. Ta wersja jest krokiem milowym i pierwszym tego typu oficjalnym wydaniem. Wszyscy proszeni są o wykonywanie bardzo szczegółowych testów, ponieważ chyba każdy chce, aby FreeBSD 5.0-RELEASE było najlepszą z dotychczasowych wersji.
FreeBSD 5.0 DP1 można pobrać z ftp://ftp.FreeBSD.org/pub/FreeBSD oraz z lokalnych serwerów mirrorujących.
Poniżej przedstawiamy listę najważniejszych zmian, oraz oficjalną notkę.

  From: Murray Stokely   To: announce@FreeBSD.org  Subject: FreeBSD 5.0 Developer Preview #1 Now Available    A Developer Preview release of FreeBSD 5.0-CURRENT is now available  for widespread testing.  This preview is a significant milestone  towards the eventual release of FreeBSD 5.0 in late 2002.  Some of the  many new features that are available in this snapshot are listed  below:        * SMP support has been largely reworked, incorporating code from        BSD/OS 5.0 (in progress).        * The random(4) device has been rewritten to use the Yarrow        algorithm.  It harvests entropy from a variety of interrupt        sources (hardware devices) to provide the entropy required by        strong cryptography.        * Support for 32-bit Cardbus devices has been added for mobile        computers (NEWCARD).        * Significant security enhancements have been made throughout the        system, including a reworked PAM implementation, ACLs, and fewer        privileged programs in the base system.        * An implementation of scheduler activations has been added to        the kernel to more efficiently handle multi-threaded        programs. (in progress).        * A device filesystem has been added to allow entries in the /dev        directory to be automatically attached.  Among other benefits,        devfs provides better support for attaching and detaching        peripheral devices.        * Support for the sparc64 architecture, including most modern        workstations and entry level servers from Sun Microsystems (and        possibly clones from Tatung, and others).        * FFS snapshots and background fsck(8).    ***************************** WARNING ********************************      This is a development snapshot, and may include serious software  bugs.  Do not install this on a machine where important data may be  put at risk.  In addition, a number of debugging options are turned on  by default, so the poor performance of this snapshot should not set  expectations for the final release of 5.0.    **********************************************************************      That said, we have done our best to provide a stable system for  developers and power-users to help test the new functionality in 5.0.  For a complete list of new features and known problems, please see the  release notes and errata list, available here:        http://www.FreeBSD.org/releases/5.0R/DP1/relnotes.html      http://www.FreeBSD.org/releases/5.0R/DP1/errata.html      Availability  ------------      5.0-DP1 is available for the i386, alpha, and sparc64 architectures  and can be installed directly over the net using the boot floppies or  copied to a local NFS/FTP server.      If you can't afford the CDs, are impatient, or just want to use it  for evangelism purposes, then by all means download the ISOs,  otherwise please continue to support the FreeBSD project by purchasing  media from one of our supporting vendors.  This Developer Preview  release is available on CD-ROM from the FreeBSD Mall.            http://www.FreeBSDMall.com/      FreeBSD is also available via anonymous FTP from mirror sites in the  following countries: Argentina, Australia, Brazil, Bulgaria, Canada,  China, Czech Republic, Denmark, Estonia, Finland, France, Germany,  Hong Kong, Hungary, Iceland, Ireland, Israel, Japan, Korea, Lithuania,  Latvia, the Netherlands, Poland, Portugal, Romania, Russia, Saudi  Arabia, South Africa, Slovak Republic, Slovenia, Spain, Sweden,  Taiwan, Thailand, the Ukraine, the United Kingdom, and the United  States.      Before trying the central FTP site, please check your regional mirror(s)  first by going to:       ftp://ftp..FreeBSD.org/pub/FreeBSD      Any additional mirror sites will be labeled ftp2, ftp3 and so on.      We can't promise that all the mirror sites will carry the larger ISO  images, but they will at least be available from:         ftp://ftp.FreeBSD.org/pub/FreeBSD/       ftp://ftp2.FreeBSD.org/pub/FreeBSD/       ftp://ftp5.FreeBSD.org/pub/FreeBSD/       ftp://ftp.au.freebsd.org/pub/FreeBSD/       ftp://ftp.uk.FreeBSD.org/pub/FreeBSD/       ftp://ftp.dk.FreeBSD.org/pub/FreeBSD/      See the FreeBSD Handbook for additional information about FreeBSD mirror  sites.      Acknowledgments  ---------------      Finally, we would like to thank the developers, users, and companies  that continue to make FreeBSD releases possible.      Many companies donated equipment, network access, or man-hours to  finance our ongoing release engineering activities, including Compaq,  Yahoo!, and The FreeBSD Mall.      I couldn't possibly list all of the people that have helped make 5.0  DP1 a reality, but the following people deserve to be singled  out. Will Andrews, Kris Kennaway, Steve Price, and the rest of the  Ports team did an incredible job fixing hundreds of third-party  packages. Robert Watson and Bruce A. Mah did an excellent job writing  up the errata file, helping to decide what changes should be made  specifically for this DP release, and much more. Jake Burkholder acted  not only as lead developer for the sparc64 port, but also as package  builder and release engineer! David O'Brien helped integrate XFree86  4.2 into this snapshot.      Please join me in thanking them for all the hard work that went into  polishing the FreeBSD -CURRENT development branch over the past  month. I would also like to thank the FreeBSD Committers  (committers@FreeBSD.org), without whom there would be nothing to  release, and the many thousands of FreeBSD users world-wide who  contributed bug fixes, features and suggestions.      Above all else, remember that this is a work in progress. Please  help us find bugs now, so that 5.0-RELEASE will be that much better.       Thanks!       - Murray
