Akoma kalytero software diathesimo... (kai oxi, den einai prwtapriliatiko asteio :-) ----- Forwarded message from Jim Gettys ----- We are very happy to announce the availability of a new stable build. It is composed of Build 368 and the Q2B85 firmware. Highlights of this stable build: 1) Working mesh network! UI to select the Mesh network! 2) Battery charging is working well at last! 3) An greatly improved web browser 4) Gnash (free Flash player; still somewhat unstable) pre-installed; Flash 9 also works, but not packaged or installed. 5) touch pad driver fix for jumping cursor: the touch pad should be much more usable, and the tablet usable on B2 systems. 6) boot time has substantially improved due to a scheduler fix. 7) battery indicator in Sugar 8) availability of Helix Media Player 9) instructions for customizing your own image 10)30% system performance improvement when any network device is in use. Please update your systems to new firmware and new Sugar environments. The firmware fixes include fixes for both battery charging to fix a battery overcharge problem, so it is particularly important to update both the firmware and the Sugar environment. Both of the firmware and the NAND image will be updated by using the procedure found here: http://wiki.laptop.org/go/Autoreinstallation_image Additionally, you can find the first content from the OLPC Library. http://dev.laptop.org/pub/content/ has links to online content http://wiki.laptop.org/go/Library has related information. http://wiki.laptop.org/go/Library_Release_Notes has release notes. We'd like to thank the people who have reported bugs; each bug is gold to us, particularly hardware bugs. *Please* let us know in trac (found at http://dev.laptop.org/: you must enable cookies) of each and every hardware failure (or strange behavior) you have, even if it happens for "stupid" reasons. Each failure, no matter what the cause (good, bad, stupid, clever, even abuse), is of great help identifying and getting problems fixed, weak mechanical components strengthened, and bad electrical components identified. In general, we'll try to get you replacement machines too, so we can find the "root cause" of malfunctioning machines. Please let us know of software problems you see too; checking for duplicate entries in the trac system and adding your report if you see a clearly matching report will also be helpful. Including the version of your hardware, the firmware version and the build number in your reports (both hardware and software) will help us greatly in identifying problems. We know battery problems have been a great pain and concern to you, and are as relieved as you will be with their resolution. For those of you with dead batteries with B2 systems, most, but not all of the dead batteries can be recovered with the systems you now have with the new firmware. Recovering batteries in the field with BTest-1 systems is harder; thankfully there are far fewer BTest-1 systems deployed. Please follow the directions in http://wiki.laptop.org/go/Battery_Charging. Please read the release notes! http://wiki.laptop.org/go/OLPC_Software_Release_Notes; they have been extensively updated. o New activities: - Calculadora, A simple calculator activity (Mauro Torres et. al. of the Tuquito Linux project in Argentina) - Blockparty (aka Tetris) (Vadim Gerasimov, J5) - Slideshow (Erik Blankinship, Marco) - xbook as an activity o Major Improvements in Activities: - Web Browser (Firefox, Marco) This version lays out pages well on our high resolution screen for a vastly improved web experience. Unfortunately, we have not had time to integrate a table of media types to a media player. - TamTam major improvements http://wiki.laptop.org/go/TamTam_Release_Notes (TamTam Team) - Write (Abiword team) Toolbar bar buttons for open,save,justity,insert image. Much less flicker on context changes and startup. Speedups for scrolling. Fixes for bugs 404,822,824,823,771,826. Other fixes. - The News Reader now ships with new, more educational default feeds, including BBC World News headlines, Wikipedia Picture of the Day, and more. (Owen Williams) Temporarily removed activities: - Journal Preview, (Marco, Tomeu) - Chat (needs tender loving care) - Memosono (needs some work) "Extras" activities - Helix Media Activity http://wiki.laptop.org/go/Helix_Media_Activity This is able to handle a huge number of common audio/video datatypes, having codecs for almost anything you can think of. (Justin Gallardo, Greg Wright, Jeff Dutchman, Martin Schwartz) - Library activity http://wiki.laptop.org/go/Library_Release_Notes Includes simple formats to neatly display directories of books and other materials o Latest Sugar is included with lots and lots of bug fixes and improvements - sugar-shell taking up 100% cpu after a while (believed fixed based on testing marco/dan/johnp) - Sugar crashes at boot fixed, by fixing Avahi and Sugar, enabling discovery of other people and services on the mesh (Dan Williams, Trent LLoyd, Chris Blizzard, Andres Salomon) - initial screen works on qemu or without a camera (fixed in 298 by marco) - nice scrollbars (fixed in 296 marco) - focus issues in some activities (fixed in 296 marco/tomeu) - not able to log in in qemu build (johnp fixed) - sugar blocks on service startup (johnp fixed) - sugar displays the battery status (marco, dcbw) - UI tuning (marco, dcbw, eben...) - New sugar API (Dan, Marco) o Wireless - New Marvell firmware - working mesh! Many bugs fixed since build 303 (Marvell, Cozybit, Marcelo, Michailis, Dan Williams, cjb) - Note: there has so far been *no* significant tuning of the mesh yet - GUI for associating with the mesh! - Support for in-mesh multicast support - Link-loss detection and route tear-down with RERR messages. This improves route restoration time. - Mesh transmission rate is done a the highest available rate for each hop. The rate for each hop is determined when the route is discovered. - Deferred route discovery. Route discovery is now done by a lower priority task, which reduces the variance of transmission time. - WDS problem workaround. Wireless interface will accept WDS replies from WDS-enabled access points. This will only work with APs that have a different MAC OUI than the xo's. (ticket #901) - Fix to select the best MPP instead of the one with the highest sequence number (internal bug #91). - Fix for tickets #861, #914, #992. o Base system fixes - Much better wireless driver (Marcelo, Dan) - Packet corruption with the wireless under heavy loads. TCP flow control change for the mesh interface that fixes it. - Tickless operation. (Thomas Gleixner, Salomon) - New touch pad driver with fully working PT/GS mode switching. (Hull, Salomon) - New kernel; the old stable was 2.6.19, this has 2.6.21-rc5 (Linux community) - Analog input mode on audio input (Kumar, Salomon) o X Window System - touch pad driver fix for jumping cursor: the touch pad should be much more usable, and the tablet usable on B2 systems. - Support for BTest-2-2 touchpads - Disable autorepeat on most keys, bug #1201 (jg) - Better X Window System performance (X.org, Jordon Crouse, Adam Jackson, cjb) o Firmware and embedded controller firmware (Quanta, Bradley, Smith, Lilian) - Much improved battery charging code and data reporting (Quanta), Bug #611. - Battery overcharging fixes (Quanta), Bug #667 - Low battery charging fixes; most, but not all dead batteries can be recovered in the field with existing B2 systems, Bug #543 (Quanta (Lui), rsmith) See: http://wiki.laptop.org/go/Battery_Charging - Battery capacity reporting fixes (Quanta (Lin et. al.) Bug #596 On B2 systems, average NiMH lifetime in a test (backlight fully on, wireless associated, all functional units on including GPU, but processor idle) was approximately 2h40m, LiFePo batteries were approximately 3h 10m. This will improve as our power management improves - System performance increase of >30% when network devices (e.g. wireless) are running; this was due to cache snooping interference by network USB devices. - Update to Q2B85 - Fixed SD boot support - Fixed problem booting from ext3 with extended attributes - USB Kensington keyboard fix - LED for battery is solid red instead of blinking - Reset the wireless chip when the firmware boots to fix wireless not showing up on boot - Beginnings of support for wireless (not yet finished, Walter). - EC now idles in very low power mode when it has nothing to do: this means the EC no longer drains the battery quickly when the battery is left in the system, but there is no power from the power adapter; this was causing many batteries to go completely dead. (Quanta) Bug #533 o EToys activity (Bert, Diego, Ian, Scott, Takashi, Ted, Yoshiki) - removed first-time startup delay by reusing Sugar's DSA key (owner.key) rather than making our own - we can now launch etoys projects directly from the web activity by clicking on a project file link - the etoys camera plugin saw major improvements, we can read video at > 20 fps now - big cursor support added to Squeak VM - improved tutorial game (demon castle) - better tutorial authoring system (Event Theatre) - for developers: binary etoys content moved out of git, download shrinked from > 200 MB to less than 20 MB o Image customization procedure only be available in firmware versions Q2B84 or higher: see http://wiki.laptop.org/go/Customizing_NAND_images Some important bugs not (yet) fixed but well underway: o suspend/resume is next: we have working firmware for suspend/resume and the systems are resuming (already faster than commercial systems); much work remains here. Thank you all for your help and support. Please note that an increasingly large fraction of the software development is from the larger OLPC community rather than OLPC staff or those of the companies involved in its production. If we've overlooked anyone, our sincere apologies.
