The most notable changes:

• bitcoind used to listen on 127.0.0.1:8334 by default. If you use Tor for incoming connections, you have to manually specify bind=127.0.0.1:8334=onion in config
• unix sockets can now be used to communicate with Tor or other proxy, and MQ traffic.
• New mempool policies has been implemented to patch some attack vectors for chains of unconfirmed transactions, especially in relation to lightning network channels and similar contracts.
• TRUC (Topologically Restricted Until Confirmation, BIP 431) can now be used with transaction version 3 (now considered standard) instead of RBF.
• Full RBF (Replace By Fee) is now enabled by default
• RHEL 8 and Ubuntu 18.04 are now unsupported due to minimum required glibc version bump.

Some nice changes here, three of note:

• private channels with LND is functioning again
• offers has gained BOLT12 support as well
• onion messages now supported by default

for those of you that run CLN, how do you like it?

Some highlights:

• Experimental support for inbound fees was added in #6703, with send support in #6934
• New config option sweeper.maxfeerate added in #7823
• You can use environment variables in lnd.conf now for rpcuser and rpcpass (#8310)

Where can I buy $500 gift cards for amazon.com with cryptocurrency?

When bitcoin topped $70,000 recently, I went to a few gift card outlet websites. But when I actually went to add a $500 gift card for amazon.com to my cart, they said it was "currently unavailable".

Did amazon.com stop selling gift cards to third parties? Or was this a temporary supply problem during the ATH?

Where can I signup for a bitcoin debit card without a phone?

There are a number of "bitcoin debit card" providers -- services that issue you a traditional visa/mastercard/etc debit card that allows you to pay for purchases in fiat, but where the balance of the card is automatically converted from your cryptocurrency balance stored on their custodial wallet.

Note that a "bitcoin debit card" is distinct from gift cards in that the balance lives in an account below the debit card, not on the card itself. This is important because otherwise you may end-up with tons of different cards with low balances. It's important for my business that I can pay invoices with a single card, and if that card expires then the balance can simply be spent on the card's replacement.

Unfortunately, I've been unable to find any providers that do not require a phone to be linked to the account.

For security reasons, I do not mix insecure devices like my phone with high-risk accounts like financial services. Therefore, it's important that I find financial services that don't require a phone number to be linked to the account (shudder at the thought of implementing 2FA over SMS) or an app.

Coinsbank requires a phone number. Wirex requires a phone number. Cryptopay requires an app (which grants access to the account to a phone). Unbanked (Ternio) is dead.

Good decision to reverse, but I still hope miners move away from F2Pool and ideally into self-hosting.

Take the back seat, #Lambo. #Ferrari accepts Bitcoin from US customers.

Looking for store indexes and core patches in particular, theres a lack of info on the available patches out there (other than ordisrespector).

So I'm curious with the whole Ledger seed backup controversy, are Ledger devices actually safe? Should I continue to use my Ledger? I don't have much so I'm not too concerned, but I'd like to still sleep peacefully at night regardless.
