This release includes the following features and fixes:

• A new getinfo RPC has been added to retrieve basic information about the

  with the -chronik option just like the other platforms.
• Starting with this version, support for MacOS 10.15 Catalina has been
  removed. The release build requires MacOS 11.0 (Big Sur) or above.

https://download.bitcoinabc.org/0.30.4/

This release includes the following features and fixes:

• The address_type field of the getnewaddress RPC is deprecated and will be
  removed in the future. This field is actually confusing as it's not setting
  the returned address type and is only there for compatibility reason. The
  documentation has been updated to clarify this behavior.
• This release contains a fix for a bug that could cause a node to delay the
  download of the latest block under certain circumstances.

0.30.3

Bitcoin ABC 0.30.3 Release Notes

Bitcoin ABC version 0.30.3 is now available from:

https://download.bitcoinabc.org/0.30.3/

This release includes the following features and fixes:

• Several minor Chronik bugs have been fixed that could return wrong data for
  some SLP type 2 mint transactions, or store extraneous content to the
  database. It is advised to upgrade if you are affected by these issues on
  your current chronik instance. No reindex is required but the first start
  will upgrade the database automatically which will take about 15 minutes.

Iguana Debugger

This release adds the Iguana debugger, a simple tool that runs the scripts of
transactions and outputs a trace of each opcode with the current stack at each
step. It also has a CSV option to view the trace in a spreadsheet software.

You can run it like this:
iguana -tx=<txhex> -value=<value> -scriptpubkey=<scriptpubkey> -inputindex=0

Or run iguana -h to see all the options.

Deprecating ARM (32 bits)

Starting with this release, the Bitcoin ABC ARM (32 bits) version is deprecated.
It will no longer be delivered with the release binaries. Users that still want
to run Bitcoin ABC on this platform should build the binary from the sources.

Network upgrade

At the MTP time of 1731672000 (November 15, 2024 12:00:00 UTC), the following
changes will be activated:

• Bump automatic replay protection to the next upgrade, timestamp 1747310400
  (May 15, 2025 12:00:00 UTC).
• Real time targeting, also known as the Heartbeat feature, will be enforced on
  the eCash network. This makes it more difficult to mine blocks faster than
  the expected 10 minutes average, preventing large bumps in difficulty that
  can lead to inconsistent block intervals. Miners need to update their setup
  according to the instructions from the eCash website.
