Hi Ujjvala, You are right I am using 6.0.3 stable version. As from the download section that was the latest one. Now I downloaded server, client & addons from http://nightly.openerp.com/6.1-dev/ I just have few questions may be trivial ones: 1. Is http://nightly.openerp.com/6.1-dev/ the right location to download & use? 2. In the current & latest installation using latest dev build server is using the addons folder at the following location: /usr/local/lib/python2.7/dist-packages/openerp_server-6.1_dev-py2.7.egg/openerp/addons how do I connect the server to the downloaded trunk version of the addons (lp:~openerp/openobject-addons/trunk)? 3. Location https://code.launchpad.net/~openerp-dev/openobject-addons/trunk-bug-856501-ucoshows the revision history as: Recent Revisions 5238. By Ujjvala Collins (OpenERP) 4 hours ago [IMP] point_of_sale: Small improvements. 5237. By Ujjvala Collins (OpenERP) 4 hours ago [IMP] point_of_sale: Improved string. 5236. By Ujjvala Collins (OpenERP) 6 hours ago [FIX] point_of_sale: Fixed AttributeError on Make Payment wizard when no demo data loaded. While if I download the same by using Bazaar Explorer then same revisions for the addons are as below: 5238. By Launchpad Translations on behalf of openerp Launchpad automatic translations update. 5237. By Antony Lesuisse [IMP] audittrail cleanup and speedup - test for auditrail before anything else - dont allocate a different cursor 5236. By niv-openerp [fix] obvious bug, field used in a on_change but not declared in the view Antony Lesuisse and Point of sale downloaded by bazaar doesnt have the changes made by Ujjavla. 4. Suppose after 1 month I want use the latest dev version with latest revisions of client, server, web. Then what will be the procedure to upgrade the latest dev version over older dev version? Please help. Thanks Amit On Fri, Sep 30, 2011 at 4:04 AM, Ujjvala Collins (OpenERP)
