Did it work with 2.60? Does it work if you sync with a local file? (Copy the database to a temporary directory and sync with the copy.) Do you have a trigger that does a save / backup? Disable it and test. cheers, Paul

You could ask on the KeePassium site. cheers, Paul

200M would take about 2.5 seconds to open on my machine so it's not too big, but it is overkill. The iterations are designed to slow down a brute force attack and you should always use them, but a strong password will more than compensate for fewer iterations because you have to perform the iterations for each password guess. Reduce the iterations (a 1 second delay is more than enough) and fix your problem without reducing security. cheers, Paul

I wouldn't call this a bug as a field reference that fails maybe worse than one that pulls data from an entry you deleted. Use the Reference Check plug-in to help manage the references. It adds a new item to the Find menu that shows all references. cheers, Paul

There is no way to know what will be changed, but it doesn't matter because all data is saved in the History so nothing is lost. To see what changed, select Find > Last Modified Entries. FWIW, I have never needed to find old data after a sync, only after an edit and once you fix that the sync will have the same data. cheers, Paul

You can export the database as CSV and then import it into Excel. Unfortunately this is only a subset of data so it may be missing important information. If you export as XML you can then convert it to CSV using the XML to CSV converter. Even better, give them a copy of the database and the password, then all data is in the original format. Use Shamir's Secret Sharing, using this implementation S4, to split the password into multiple segments and give them to family members. Copy the database to...

You didn't say the Tools option didn't work if you change the password, so I missed the subtle addition. A better name for the new button would be "Copy New Password" and it would be greyed out if you hadn't changed the password. cheers, Paul

It is unlikely an attacker would delete your database - why raise any suspicion when you want to steal someone's stuff? I suspect you have inadvertently moved the database or forgot where you stored it. KeePass can search for databases via the File > Open > Find Files options. cheers, Paul
