Bitmark wallet development reaches a Core 27 prerelease

Historical retrospective compiled on 24 October 2026. Month-end retrospective on the 2025 wallet identified by the project; also covers its listed 2024 predecessor.

Evidence: Project wallet listing and prerelease announcement.

Bitmark’s wallet page identifies version 0.9.7.6 with 2024 and version 27.1.0 with 2025, documenting a newer line of client work beyond the original 0.9.7 releases. The development repository describes the 27.1.0 release candidate as a merge with Bitcoin Core 27.x that preserves compatibility with previous releases without a fork. GitHub labels this build as a prerelease, a distinction that remains important even when a download page presents it prominently. This entry records the software announcement and its stated compatibility goal, rather than claiming universal deployment or an independently audited security improvement.
