It was also possible - and I assume that's what you were doing - to view and edit the HTML source of a note, thanks to the HTML button. It has been removed in 5.0, so you can't access it anymore.
Images with external src values should still work.
(more details: I think I read somewhere that once we switched to zotero5 beta, there is no way to roll back to zotero4 (my understanding of the reason is that Db may be structured differently so once the DB have been ported to zotero5, zotero4 can't read it anymore.) But according to Gracile, it seems possible to use the different versions (on two different computers) to sync on the same account so my reasoning seems to not be correct -at all-)
Technically it is thus possible to roll back: if I update one of my computer to Zotero5 but not the other. Then if I want my computer with the updated version to switch back to zotero4 I can simply copy/paste the "zotero4 folder" from the other compyter and reinstalled zotero4. Is this reasoning correct?
There's been a steady trickle of bugs that Dan and co. have been fixing -- admirably quickly, but still.
E.g. Brenton's initial upgrade didn't work at all initially. Which is fine, that's what beta testing is for, but there is an expectation that beta testers are OK with experiencing issues like that (as Brenton was). But if you're writing a grant or a dissertation due in a month, you may not have that patience.
There are other issues (no BBT, no Scaffold unless you're running the git source in Firefox developer edition), so yes, assume that people posting here regularly have good reasons not to be on 5.0.
(back in the day, when I was still a whippersnapper, I finished my PhD thesis with Zotero 2.0.9 as a safety precaution, forgoing the switch to citeproc-js and CSL 1.0 made in Zotero 2.1, and even then Word 2003 still managed to corrupt my thesis .doc file)
BTW, I love your passionate defense of 5.0 Beta, it has brought me really really close to switching over!
@bwiernik Thanks. I take regular backups. My concern with one computer on 4.0.29.x and another on 5.0 Beta is if somehow the Beta ends up corrupting all three databases (incl the online), forcing me to roll-back to my pre-upgrade database. This is probably a very far fetched situation, but still.
Edit: works now, installed an update to 5.0-beta.136+469d689
1) Running `./zotero-bin` seems to start another Firefox instance, nothing happens. What's the correct way to run/upgrade Zotero5?
2) Running `./zotero`: this does start Zotero 5, offers to upgrade the database, and seems to work, but with these messages:
zotero:1882): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->ref_count > 0' failed
(zotero:1882): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed
I saw some forum threads regarding similar errors pointing to possible permissions problems with .cache, .zotero, .gnome2 etc., but I didn't find any such issues on my system. I'm running Zotero5 from ~/Programs/zotero/.
3) I had Zotero for Firefox 4.0.29 installed. I believe this thread mentions the addon should be upgraded automatically to Zotero Connector when updating to Standalone 5 beta? This didn't happen. I uninstalled the old addon and installed the connector from zotero.org/download/. But the connector extension seems to be the same as "Zotero for Firefox" (namely zotero-22.214.171.124.xpi)? Is there a different connector version to be used with Standalone 5.0? (I get this message when starting ZS5 beta: "This Zotero database requires Zotero 5.0-beta.136+469d689 or later. Current version: 126.96.36.199 Please upgrade to the latest version from zotero.org.", although the program subsequently does work.)
Otherwise, Zotero Standalone seems to work nicely. Am I doing something wrong, or should I file some issues? Thanks!
3.) The Firefox connector for the beta is listed here: https://forums.zotero.org/discussion/comment/267549/#Comment_267549
The auto-update would have happened if you started by installing that (and it may still do that). Note that this is obviously more clumsy given the beta nature and the continued availability of the 4.0 versions. This should be obvious once 5.0 is actually out.
Since I didn't see any version string in the https://www.zotero.org/download/connector/dl?browser=firefox url, I tried removing the "?browser=firefox" and the "dl" parts to see if those would work, and then I got just the regular 4.0 download page.
Is there a direct link to the correct download?
It doesn't work when opening the link in a new tab, or copy-pasting. But following the link in the same tab does work.
And thanks for your quick answers, much appreciated!
