elogd 3.1.4

Our elog instance (elogd 3.1.4 built Jan 13 2021, 20:44:20 revision ce2a48e9) has been running for years without any problems.

We have a new user who consistently crashes the elog:

update elog downloads page

The elog downloads page is slightly out of date, https://elog.psi.ch/elog/download.html

1) the "git clone" instructions work (but there is no git tags corresponding to different releases, I suggest adding test: "elog developers 
recommend always using latest version from elog git repository").

2) "elog source code", recommends downloading tar file, but latest tar file is from February 2023, probably out of date. people who can compile elog 
from sources can do "git clone", is the "tar" method still relevant?

3) windows binaries, latest available is from 2018, before the famous security fixes, probably no longer safe for running on the open internet. I 
suggest we remove this section and say "sorry, windows binaries no longer available".

4) linux binaries, all links are dead, and we have requested removal of elog packages from red hat, debian and ubuntu. (and they have been removed).

K.O.

You were correct . This is 100% a browser issue , Thanks for your assistance.

Below are the MIME types hard-coded into elogd. As you can see there is neither .ods nor .eml. If you give me the MIME type, I can add that easily. I wonder however why both work differently for you. I believe this is a browser setting.

I gave it a shot with no luck

On my client (Kubuntu) an ".eml" is associated with mime type "message/rfc822" . Just adding this to the list seemed to have no effect so there must be more to it than that :}
