Actually there have been vulnerabilities discovered in hardware wallets and Electrum 3.3.8. It's called Fee overpayment attack on multi-input segwit transactions

That has been patched by Ledger in one of their software updates a few weeks back. Besides, that attack was not exclusive to Ledger and Electrum's version 3.3.8. Plenty of other brands were affected. Some patched it already, others waited and did it in future updates.

I assume you are talking about this:
https://support.ledger.com/hc/en-us/articles/360014191540-Massive-transaction-fees-in-BTC-and-BTC-based-apps

I replied to your post because you said "Unless a vulnerability is found with 3.3.8 I am not really in a hurry.", and I pointed out that vulnerability has indeed been found month earlier in electrum 3.3.8 (And other software as you mentioned, Ledger etc), so it's not safe to use 3.3.8.
And latest Electrum 4.0.3 has been released on 11 September and it restores compatibility for PSBT after this vulnerability previously discussed, it has it's own CVE now: http://cve.circl.lu/cve/CVE-2020-14199
So definitely it's recommended to stay with latest Electrum and latest Bitcoin Core at the moment.

Trezor firmware upgrade info: https://blog.trezor.io/details-of-firmware-updates-for-trezor-one-version-1-9-1-and-trezor-model-t-version-2-3-1-1eba8f60f2dd
Description of the attack on Optech Newsletter: https://bitcoinops.org/en/newsletters/2020/06/10/

I waited with Trezor firmware upgrade until Electrum 4.0.2 was released, now I have upgraded both, it works fine.

Releasing a lot of updates in short times will be detrimental to beginners, even though the mistake is made of them not checking the message.
Can anyone tell us, do recent updates deserve a new version?

Maybe because some of the updates are trivial for some android phone users.

The merged PR here that were 9days-old and earlier were the updates included in the latest version 4.0.2 (from v4.0.1):
https://github.com/spesmilo/electrum/pulls?q=is%3Apr+is%3Aclosed
The first 6 in the list, specially the "back button" issue, which I didn't experienced.

If they don't check the messages they may be very well still on 3.3.8.
...Also the beginners can and should set in-wallet notify for new version.

It's not in those screenshots, he needs to tap the wallet name above (upper-left) to display the 'wallet information'.

-snip-
Seems I can't backup, it say Backup directory not configured.

- How much minimum btc required to create channels?.

The minimum for Electrum is 0.002BTC plus fee.

For the backup, you need to enable it first in the 'Menu->Settings->Backups: No -> Yes'.
Or you haven't granted Electrum a "file management/storage permission" yet.

What you have created is a non-expiring "request"... it's like creating an invoice and sending it to a client...

If all you want is an "address" that someone can send funds to, then click that entry in the list, then click the "address" tab at the top-right of the "Receive" page:

NOTE: It is only pending, because has detected that no funds have been sent to that address yet, so the "request" has been filled Wink

So you will be able to receive the funds sent to that address.

Alternatively, you can use "View - Show Addresses" and then click on the "Addresses" tab and select an address from that list.

I am quite new to electrum and just downloaded their latest release. I am wondering what does the "pending" means after I requested an address that doesn't expire? also, is it ok to use the address while it is in pending will I be able to receive BTC from it? TIA!!!

On my local board, my friend sharing about a mobile phone aplication have a bug where lightning network enable button disappear in wallet information.

I'm using v4.0.2 arm-v8-64bit and there's an "Enable LN" button below the wallet information (third button)...
It's just grayed out since my watch-only wallet is P2SH-SegWit.

However, now it offers Lightning support. If you want to use lighting you would have to update.

There isn't any great difference between the two, so I agree, no need to hurry to update
