The Bitcoin development team has unveiled a new update: Bitcoin Core version 29.3, officially released on February 10, 2026.
This update brings multiple bug fixes and enhancements in performance, alongside refreshed language translations to improve user experience globally.
Key modifications affect peer-to-peer networking, transaction validation processes, and wallet functionalities. Specifically, wallet improvements now detect spending of zero-value outputs and introduce tests for anchor outputs within wallets. Additionally, the release addresses a previously unidentified issue during legacy wallet migration by implementing further cleanup procedures. It also resolves a migration problem that prevented converting watch-only legacy wallets into spendable ones.

A critical bug was identified in versions 30.0 and 30.1 of the Bitcoin Core wallet software related to wallet migration under rare conditions. When migrating legacy Berkeley DB (BDB) wallets on the same node without proper backups, all associated wallet files could be deleted inadvertently—posing a risk of permanent fund loss.
To address this issue promptly, developers issued release candidate v30.2rc1 on January 8 as a minor patch following version 30.1 to fix the legacy wallet migration failure effectively.
Bitcoin Market Overview
At present writing time, Bitcoin’s price declined by approximately 2.92% over the past day to $66,873 amid widespread selling pressure across cryptocurrency markets early Wednesday morning.
The broader crypto sector mostly traded lower as investors awaited key economic data—the delayed January jobs report scheduled for release at 8:30 AM ET by the U.S Bureau of Labor Statistics—which influences market sentiment significantly.
Since peaking above $126,000 in October last year at an all-time high level for BTC futures contracts (likely referring to synthetic or derivative prices), Bitcoin has experienced sustained downward momentum with intensified selling throughout recent weeks.
The digital asset dipped below $70K on February fifth before briefly hovering just above $60K—a psychologically important support zone—before recovering back above $70K but struggling to gain upward traction beyond roughly between $66K and $72K range since then.
This places Bitcoin currently down nearly half (-46.94%) from its record peak value recorded several months ago.
