Upgrading Drupal

Is it there any difference upgrading from 4.5.1 to 4.6.

? Or is it better to take smaller steps and follow the presented migration path 4.5.1 > 4.5.2 > 4.5.? > 4.6 ?

thanks

How about this?

"The HTML code for the primary links. If this field is empty, Drupal will automatically generate a set of links based on which modules are enabled." ?

That message written under admin/themes/settings Primary link textarea. But now (in Drupal 4.5.2) set of links don't generated.

Before 4.5.0 I used menus and was very happy with the block level functionality it gave me as far as creating menus anywhere and in whatever way I liked. Now with 4.5.0, even though the menus module works, I figured I'd use the built-in drupal functionality with menu_on-the-fly. Things went pretty quickly and everything was working great till I tried to click on one of the group elements that was collapsed. (ie/ http://www.razing.net - look for Games, Avernus Cube, Karmic Retribution 2, etc). It defiantly refused to expand.

So I tried a few different things; the first of which was to create another quick drupal site since I was upgrading and I figured this to be a database issue. So I added in the module, created a new menu group, added two menu item that pointed to nowhere (the second being the child of the first), loaded up the block, and clicked on the parent. Low and behold it expanded. So I compared 'menu' from one database to the other, everything looked in order.

Then I decided to replicate the same exact process on my live site, on a hunch that it was working on the test site because of the invalid target. Sure enough. To double check myself I went back to the test site and added pointers to actual content, clicked on the parent node to see if it would expand, nada. It was staying collapsed and that was that.

So I dinked with menu_otf.css, menu_otf.module and despite having tried to remove all instances of 'collapsed' the block still stubbornly refuses to expand any group item that points to valid content.

Hello,

I am updating from 4.3.1 to 4.5.0 on easylum.net, and followed all the instructions. I click the link to update the script at http://www.easylum.net/update.php, and I get a blank page. I double checked conf.php. Everything looks right.

This doesn't make sense to me.

I had tried 4.5.2 before, following the instructions and adding the appropriate additions for 4.3.x and 4.4.x via SSH/MySQL. Something's definitely FUNKY, because I can't see anything but blank pages, even after clicking the link on update.php.

I'm getting a bug in codefilter when I upgraded to 4.5.2

Fatal error: Call to undefined function: drupal_set_html_head() in /home/fowmgrei/public_html/modules/codefilter/codefilter.module on line 21

I added my problem to the outstanding bug for codefilter:
http://drupal.org/node/10317

Isn't it strange that it wasn't a problem for me with 4.5 or 4.5.1?
