There might be a mistake or two in this, but it's accurate to my knowledge.

[edit] Tony's picks as best of the bunch: 4.19, 4.32, and 5.1.3

Well, if you starts listing all alpha-builds you should list all from v4.05 to v4.27, and all from v4.50 to v4.67... there was actually also a couple "extra" builds thrown in around v4.60...

Also, before v4.70 you had v5.0, but due to not having removed all major-version-checks it was pulled and downgraded to v4.70.

Especially among the many alpha-builds there's some nasty bugs, like most of the v4.5x-series having an upload-bug...


As for "release-builds", CPDN in my recollection used v4.03 on release in August 2004 or maybe mis-remembers so v4.04 was used, when the other projects later upgraded had jumped to v4.05. In fairly short order v4.09 and v4.13 was released. Later, v4.19, v4.25, v4.43 and v4.45... well, actually v4.18 was "recommended" release for a couple hours before v4.19 was released instead... v4.20 was never released outside alpha, and AFAIK v4.35 was not released either, but still many tested (and complained) about v4.35...

Next release will be v5.2.x

v4.68 was built for CPDN-beta, and CPDN-beta also used some more v4.0x-builds before v4.03.


While upgrading to a higher version normally isn't a problem, except for v4.19 and earlier to later versions, must always uninstall before downgrading. But, users downgrading to v4.13 sometimes got a nasty surprise with their CPDN-results, and there is a slight possibility of other surprises on downgrading...


As for "best" in the family, this is as noted v4.19 and v4.32, while v5.1.5 is slightly better than v5.1.4 and this is slightly better than v5.1.3... and most likely v5.1.6 or v5.2.x whichever is built next, will be even better...

Due to some bugs it's possible to stumble-over if you're unlucky, would not run v4.19 or earlier on any computer attached to more than one project, and if multi-project would not use anything before v4.32...
Due to all the nice new features like the new cpu/download-scheduler, would recommend v4.43/v4.45 (depending on OS), and not still use any of the earlier builds.
v4.7x introduces some bugs of it's own, so isn't really any improvement over v4.45, only with v5.1.3 and later is there any improvements over v4.45.

I had updated my previous reply to ask about CPDN. I feel I should know what that's about...

Climate Prediction Dot Net, found here, it runs models of climate change predictions, each work unit can take up to several months to process, dependant on the speed of your computer.

Welcome to Boinc, it's great seeing so much enthusiasm from a new participant :-)

Ack! Edited for far too many syntax errors; it's far too late; going to bed!

Bye for now, Ken Phillips

Yep! I should do the same. As for CPDN, I guess I'll steer clear of that if I don't want to participate in the warming up of the atmosphere! You know, my AMD Duron overheating with the processing (;-> Thanks for the good word about the enthusiasm and all but when I see the previous answer from "mmciastro" and the BOINC comming-into-being, I'm no match! LOL

OK, Now that I officially have no life, here's a list of the progression of Boinc as I understand it. It started with a gui, but no manager. Then a Manager was brought into being. Later a "scheduler" was added to the gui and manager, and that brings us to the current versions (of course, I'm omitting the hundreds/thousands of small changes and different supported OSes). All listed are windows versions and in order of development:

GUI Versions
developmental: 4.05 > 4.09 > 4.13 > 4.14 > 4.15 > 4.16 > 4.17 > 4.18 > 4.19
official release 4.05, 4.09, 4.13, and 4.19
3rd party released 4.68 (TMR maybe, also might be linux)

GUI + Manager
developmental 4.55 > 4.56 > 4.57 > 4.58 > 4.59 > 4.60 > 4.62 > 4.63 > 4.64 > 4.65 > 4.66 > 4.67 > 4.20 > 4.21 > 4.22 > 4.23 > 4.24 > 4.25 > 4.26 > 4.27 > 4.30 > 4.32.
official release 4.20 > 4.25 > Maybe 4.32 or 4.30????

GUI, Manager, + new scheduler
developmental: 4.35 > 4.36 > 4.37 > 4.38 > 4.39 > 4.40 > 4.41 > 4.42 > 4.43 > 4.44 > 4.45 > 4.46 > 4.47 > 4.48 > 4.49 > 4.70 > 4.71 > 4.72 > 5.1.1 > 5.1.2 > 5.1.3 > 5.1.4
official release 4.35 > 4.43 > 4.45

BOINC question? Look here

I guess you're saying that de-installing a previous version of BOINC should not delete its "projects" directory / sub-directory structure nor should the installation of the newer version (when using Windows XP)...

bingo

OK; to sum it up then, I have upgraded the right way by de-installing BOINC 4.19 prior installing 4.45 and it was pointless for me to copy the WUs into new 4.45 directory for the new version to process the WUs downloaded by 4.19.

You must uninstall v4.19 or any earlier version before upgrading to v4.25 and later, but as long as you install the new version to the same directory the old version was using you will not lose anything.

Changing from c:\\old-dir1 to c:\\new-dir2 on the other hand can lead to problems, even if you've copied all files from c:\\old-dir1 to c:\\new-dir2.


Anyway, as long as you're not running CPDN, it's not really a problem some results got lost, at worst you'll loose a couple hours crunching, and possibly slow-down validation of wu.

OK, another one without a life (I guess I'm part of them)... I guess you're saying that de-installing a previous version of BOINC should not delete its "projects" directory / sub-directory structure nor should the installation of the newer version (when using Windows XP)... Oh! By the way, what is CPDN?

it's not on all forums we get such a quick response! 8-)

The other people in those forums must have a life.

LOL

Yeah! They're out of this world!!! (;->

As far as loosing work, it's understood nothing's lost since there are multiple submittals for each WUs; if one computer doesn't properly process one WU, another one will and the "imported" WUs will effectively not be processed by my current computer. Conclusion: I should delete the "imported" WUs since they only take up memory space.

Finally, the merging operation seems to have worked for me, thanks to you all, it's not on all forums we get such a quick response! 8-)

The whole Boinc software changed between 4.19 and 4.20. You can upgrade from 4.43 to 4.44 to 4.45 to 4.72 etc by installing right over the top of the old one and not lose work. When upgrading from 4.03-4.19, and any 4.5x and 4.6x versions to the newer 4.45/4.72/ and 5.x.x versions you have to "uninstall" boinc prior to installing the new one to avoid losing work.

the original poster has lost those units but shouldn't worry about it and just keep on crunching.

can I add anything else?

Ummm, wow!. ouch!

Is forcing a new host ID a feature of the 4.45 version?

Bummer!! (if it is)

Dave

I dont think so.

I usually just copy the new boinc client over the old one and let
it pick up where the old one stopped.

The linux install is quite different to Windows, though...

Ummm, wow!. ouch!

On previous BOINC upgrades I've done, already resident WUs
have not been lost. Usually, even the WU already in progress
picks up right where the last version quit working, quite
seamlessly. Isn't the ability to process a WU a function of
the application (Seti@Home) rather than BOINC?

Beyond that, I've never seen a BOINC upgrade change my host ID. I
have one host with a rather low ID, and I hope I don't lose that,
just for panache!

But, then, I've not upgraded to 4.4x (still at 4.19 BOINC - works
fine, lasts long time).

Is forcing a new host ID a feature of the 4.45 version?

Bummer!! (if it is)

Hello all!

I'm a new BOINC user for the SETI project. I had initially downloaded and installed version 4.19 of BOINC, I had started processing work units but decided on upgrading to BOINC version 4.45.

Before getting rid of BOINC 4.18, I had copied work unit files from its directory into the new equivalent version 4.45 directory. The problem is that BOINC does not seem to process these "imported" WUs; how could I resolve this? Thank you in advance for your help.

These WUs are lost, I'm afraid. They're assigned to the host ID of your previous
installation, which is now lost.

But there's no harm done, since each WU gets sent out 4 times to different hosts,
and it doesn't matter much if one result is not returned.

You can use the "merge hosts" function to join the two computers in your account
if you like.

Regards Hans
