This should be the final release candidate before v30.0 is tagged. Instead of producing a 4th rc, and delaying the release further, a number of (mostly IPC related) changes have been pushed to v30.1, they can be found here: github.com/bitcoin/bitcoi…

We've made some changes to bitcoincore.org, to make Security Advisories easier to find, and the content of pre-annoucements more clear. You can find the updates here: bitcoincore.org/en/security-ad…

v28.3rc2 has been tagged, with only a handful of additional changes since rc1. See here github.com/bitcoin/bitcoi… & github.com/bitcoin/bitcoi…. This will likely become v28.3 final.

We've released v29.2. If you're running a 29.x release, and not upgrading to 30.0 (waiting for a 30.1, BDB removal, API changes etc), you should consider upgrading to 29.2. A 28.3 release will also become available soon, likely later this week: github.com/bitcoin/bitcoi….

We’ve released v28.3. If you’re running a 28.x release of Core, consider updating. This release contains a number of bug fixes.

These advisories are now available. Since the pre-announcement, one of the advisories was upgraded from low, to medium severity, meaning today there are only 4 disclosures. You can find all the details here: bitcoincore.org/en/security-ad…

Nice write up by Brink grantee Sebastian 🟩🥕, comparing the performance of ECDSA signature validation in libsecp256k1 and OpenSSL. Nearly 10 years on, libsecp256k1 is ~8x faster than OpenSSL, and performance improvements continue to be made. The devs have been doing

Brink has been engaging more devs, to do more things. Security & maintenance work carries on.

The last 3+ years worth of work, and all future work, done by Gloria, instagibbs, Suhas Daftuar & Pieter, on Package Relay, Cluster Mempool and Ephemeral Anchors will prove to be invaluable for turning bitcoin into the internet money we all want it to be.

Cluster mempool will ship in Bitcoin Core v31

If you are Guix building Bitcoin Core, be advised that the SDK tarball we use as an input for the macOS build is changing. Its script is being modified, so that it can continue to be generated deterministically. You can find more details here: github.com/bitcoin/bitcoi…

If you’ve ever donated to Brink, you should scrutinise how we’re spending your funds. We’re working hard to maintain the Bitcoin codebase, and expanding our security and maintenance efforts. We’re raising to fund more fuzzing engineers and infra; now’s a great time to donate.
