I heard others are saying that the upgrade is optional

That's true.

What does this mean to those who are still using the old version? Will this affect them in terms of functionality or perhaps the likelihood of not being able to connect to the block chain or poor connection to related services. I am a newbie and doesn't know much about upgrades. Hopefully somebody can help. Thanks!

Bitcoin Core is designed to be backward compatible, so there shouldn't be problem with connecting to other Bitcoin nodes (unless your version of Bitcoin Core is extremely old) and existing feature also will keep working. But you'll miss various new feature, optimization and bug fixes.

Thank you very much for this information! It's hard to just do things without much knowledge these days. A lot of upgrades are happening all around the corner and for person who doesn't know much, it is a very good idea to really ask for help. Thank you for this wonderful information.

You could also read the release notes (e.g. at https://bitcoincore.org/en/releases/25.1/ or also at https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-25.1.md).

Look there what has changed or what issues might have been fixed and if it's of particular importance for yourself or not. Usually nothing really breaks and if it could it would be clearly highlighted.

I personally don't rush updates of my Bitcoin Core nodes. I'm mostly on v25.0 and just one testing node is already on the newest v25.1.

Your questions are turning more and more offtopic to this thread. I suggest you hop over to nullama's guide to solo mine Testnet bitcoins and see what you can get from his guide for your own purpose.

There might also be more guides on the mining Testnet coins topic in this forum. You probably should invest some time to use the forum's search or use https://ninjastic.space/ to search the forum. It's not rocket science to figure out some search keywords that give you helpful hits.

Thank you for your response. And of course, it's not rocket science. But if it was easy to find, I would've found it. There's a difference between finding some out of date information that put you in the kinda right direction vs. actually finding the answer to your problem. In reality, there are not that many people in the world who mine mainnet bitcoin. So finding people who mine testnet bitcoin is even smaller than a needle in a haystack. I understand the the discussion is getting off topic. Ending it here. Thanks again for your reponse.

Thanks guys. I was able to configure the bitcoin.conf to testnet and now the Bitcoin Core is running on testnet with the green logo. I did insert some rpc info like user/pw ports etc. I opened those ports. Does anyone have any info on how to set up a testnet pool to connect your miner to it? Thanks for your response. I also found another option to run a bitcoin full node via bitnodes. They have a one line command that you can run on your VPS or something. I just haven't figured out how to configure that one to testnet. I kept getting errors on it.

In the Setting Options on the wallet UI, I clicked on Open Configuration FIle, but nothing happens. Do I need to create another configuration file for it via CLI? Or do I add the rpc server info to the bitcoin.conf?

Why nothing opened after you clicked in the GUI is not obvious to me, but it depends on too many not provided details.

In the bitcoin.conf file you can have sections specific to Mainnet and Testnet, e.g.

Code:

# Options only for mainnet
[main]
...

# Options only for testnet
[test]
#dbcache=2000
#blocksonly=1
maxuploadtarget=0

# Indexes
txindex=1
blockfilterindex=1
coinstatsindex=1

# Network
#listen=1
listenonion=1
proxy=127.0.0.1:9050
bind=127.0.0.1
onlynet=onion

# Connections
#rpcuser=...
#rpcpassword=...
port=18333
rpcport=18332
rpcbind=127.0.0.1
rpcallowip=127.0.0.1

# Options only for Regtest
[regtest]

# Options only for Signet
[signet]

This way you can keep the configuration all in one file and location and the appropriate options are read with whatever net you fire up your bitcoind or GUI.

I would recommend to use the Bitcoin Core Config Generator by Jameson Lopp: https://jlopp.github.io/bitcoin-core-config-generator/
Github sources: https://github.com/jlopp/bitcoin-core-config-generator

Hey guys. I switched Bitcoin Core to running on testnet. I have a couple of questions on that. I want to start solo mining tBTC. Can I prune the data when running on testnet? Or do I need the full blockchain db?

Yes, it is like mainnet. You don't need to store the whole blockchain, all you need is the chainstate (ie. the UTXO database) so you can prune the chain. But you still need to download and verify all blocks to build the chainstate before you can discard the old ones in the process called pruning.

is there support for the latest version of kali linux now?

Bitcoin Core does not publish official releases for any particular linux distros. The published linux binaries should work on any linux distro so long as the CPU architecture is supported.

I'm curious though, what is the minimum supported glibc for these binaries (i.e. which one is it built against) and do you have any plans to change that?

I was always checking on bitcoin.org for the current release. Now I know to come here for current releases.

bitcoin.org is a simple mirror of the bitcoin core releases that sometimes updates with a delay. Topics like this on this forum are also announcements that can also be delayed.
The direct link to check for updates on bitcoin core project are bitcoincore.org website (the first link in OP) or the https://github.com/bitcoin/bitcoin repository that contains the source code.

A row stating whether or not it's wallet is a custodial or non-custodial wallet would have been more expository.

The wallet is a non-custodial, as it has always been. It's not as if this is going to change between releases - there's no reason to restate the existing features for every single release. This isn't a new product announcement - it's a new version announcement.

Compatibility

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.15+, and Windows 7 and newer. Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them. It is not recommended to use Bitcoin Core on
unsupported systems.

Notable changes

From the above the unsupported system can also be some Unix-like systems right? Or shouldn't a list of unsupported systems be given for clarity?

Updated RPCs

All JSON-RPC methods accept a new named
parameter called args that can
contain positional parameter values. This is a convenience to allow some
parameter values to be passed by name without having to name every value. The
python test framework and bitcoin-cli tool both take advantage of this, so
for example:
bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1
Can now be shortened to:
bitcoin-cli -named createwallet mywallet load_on_startup=1
The verifychain RPC will now return false if the checks didn't fail,
but couldn't be completed at the desired depth and level. This could be due
to missing data while pruning, due to an insufficient dbcache or due to
the node being shutdown before the call could finish. (#25574)
sendrawtransaction has a new, optional argument, maxburnamount with a default value of 0.
Any transaction containing an unspendable output with a value greater than maxburnamount will
not be submitted. At present, the outputs deemed unspendable are those with scripts that begin
with an OP_RETURN code (known as 'datacarriers'), scripts that exceed the maximum script size,
and scripts that contain invalid opcodes.
The testmempoolaccept RPC now returns 2 additional results within the "fees" result:
"effective-feerate" is the feerate including fees and sizes of transactions validated together if
package validation was used, and also includes any modified fees from prioritisetransaction. The
"effective-includes" result lists the wtxids of transactions whose modified fees and sizes were used
in the effective-feerate (#26646).
decodescript may now infer a Miniscript descriptor under P2WSH context if it is not lacking
information. (#27037)
finalizepsbt is now able to finalize a transaction with inputs spending Miniscript-compatible
P2WSH scripts. (#24149)

Changes to wallet related RPCs can be found in the Wallet section below.

Build System

Wallet

The minconf option, which allows a user to specify the minimum number
of confirmations a UTXO being spent has, and the maxconf option,
which allows specifying the maximum number of confirmations, have been
added to the following RPCs in #25375:
- fundrawtransaction
- send
- walletcreatefundedpsbt
- sendall
Added a new next_index field in the response in listdescriptors to
have the same format as importdescriptors (#26194)
RPC listunspent now has a new argument include_immature_coinbase
to include coinbase UTXOs that don't meet the minimum spendability
depth requirement (which before were silently skipped). (#25730)
Rescans for descriptor wallets are now significantly faster if compact
block filters (BIP158) are available. Since those are not constructed
by default, the configuration option "-blockfilterindex=1" has to be
provided to take advantage of the optimization. This improves the
performance of the RPC calls rescanblockchain, importdescriptors
and restorewallet. (#25957)
RPC unloadwallet now fails if a rescan is in progress. (#26618)
Wallet passphrases may now contain null characters.
Prior to this change, only characters up to the first
null character were recognized and accepted. (#27068)
Address Purposes strings are now restricted to the currently known values of "send",
"receive", and "refund". Wallets that have unrecognized purpose strings will have
loading warnings, and the listlabels RPC will raise an error if an unrecognized purpose
is requested. (#27217)
In the createwallet, loadwallet, unloadwallet, and restorewallet RPCs, the
"warning" string field is deprecated in favor of a "warnings" field that
returns a JSON array of strings to better handle multiple warning messages and
for consistency with other wallet RPCs. The "warning" field will be fully
removed from these RPCs in v26. It can be temporarily re-enabled during the
deprecation period by launching bitcoind with the configuration option
-deprecatedrpc=walletwarningfield. (#27279)
Descriptor wallets can now spend coins sent to P2WSH Miniscript descriptors. (#24149)

A row stating whether or not it's wallet is a custodial or non-custodial wallet would have been more expository.

New RPCs

The scanblocks RPC returns the relevant blockhashes from a set of descriptors by
scanning all blockfilters in the given range. It can be used in combination with
the getblockheader and rescanblockchain RPCs to achieve fast wallet rescans. Note
that this functionality can only be used if a compact block filter index
(-blockfilterindex=1) has been constructed by the node. (#23549)

I have assembled a watch-only wallet of more than 21000 combo(PubKey) descriptors and before v25.0 it took literally ages to rescan over the whole blockchain. Now with v25.0 I saw a significant speed-up. I wish I had this version quite some months ago. I ran a part of this wallet's rescan on a low energy consuming Raspberry Pi which isn't known for its computing power, so I was aware that it can take a while. But I didn't anticipate that with prior versions of Core it would take months for the rescan!

25.0 Release Notes

Bitcoin Core version 25.0 is now available from:

https://bitcoincore.org/bin/bitcoin-core-25.0/

This release includes new features, various bug fixes and performance
improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/bitcoin/bitcoin/issues

To receive security and update notifications, please subscribe to:

https://bitcoincore.org/en/list/announcements/join/

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes in some cases), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on macOS)
or bitcoind/bitcoin-qt (on Linux).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but it might take some time if the data directory needs to be migrated. Old
wallet versions of Bitcoin Core are generally supported.

Compatibility

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.15+, and Windows 7 and newer. Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them. It is not recommended to use Bitcoin Core on
unsupported systems.

Thank you for your helpful post. I hope it helps our local people to get the benefit of it. I want to convert your post to my local language. Also, I'll publish your remarkable helpful post on our local community board named Bengali. You can see the post by clicking the above link.

I think many linux users also use package managers which will handle this automatically.

Is that enough to hanle all binaries? Only by copying bitcoind? What about bicoin-cli and all other binaires?
I was expecting to see some instructions for installing from scratch. Like cloning repository, or at least downloading source code, installing dependencies, and minimal commands to compile, make and install binaries!
What I see in the docs (./docs/INSTALL.md) is mostly for Ubuntu specific distro.

I cannot find either any reference to any package related to bitcoin in my Debian package manager

Personally I just upgrade by coping the tarball extraction over /usr/local. It's always been a hassle-free experience. Although, I don't see Bitcoin Core in the Ubuntu repositories. (I am not sure about Debian or Arch though.)
