5.5.1.13-testnet

Gridcoin releases

Gridcoin 5.5.1.13 - Testnet Release This is a testnet pre-release covering 11 merged pull requests since 5.5.1.11-testnet (27 October 2026). Most of it falls into four areas: the Debian 12 and 32-bit x86 failures found by the OBS package builds, now fixed and built in CI; the miner's ordering of block candidates, now exact on every platform; how the node handles peer messages; the GUI's theme switching and the staking tooltip. As with 5.5.1.5 through 5.5.1.11, no consensus rule change…

5.5.1.11-testnet

Gridcoin releases

Gridcoin 5.5.1.11 — Testnet Release This is a testnet pre-release covering 34 merged pull requests since 5.5.1.9-testnet (15 October 2026). It is a smaller release than 5.5.1.9. Most of it falls into four areas: the wallet's handling of its own unconfirmed sends; beacon advertisements that could get stuck; Windows data directories and wallet files with non-ASCII names; the build itself, which now compiles with no warnings on every CI platform and fails CI if one appears. Several more v15…

5.5.1.9-testnet

Gridcoin releases

Gridcoin 5.5.1.9 — Testnet Release This is a testnet pre-release covering 152 merged pull requests since 5.5.1.7-testnet (25 August 2026). Most of it is correctness work, and most of that is in the wallet: how the wallet is unlocked; what happens to your unconfirmed transactions across restarts, evictions and reorgs; what the staking balance counts. There is also a round of voting fixes, a reworked network time sampler, stability fixes for Windows and macOS, and several v15 consensus changes…

5.5.1.7-testnet

Gridcoin releases

Gridcoin 5.5.1.7 — Testnet Release This is a testnet pre-release covering 33 merged pull requests since 5.5.1.5-testnet (15 August 2026). It is a consolidation drop rather than a feature release: most of the work is security hardening, a large internal refactor that finally retires main.h, and packaging fixes that make multiprocess usable on macOS and Debian. As with 5.5.1.5, no consensus rule change activates in this build. Please run it, use it normally, and report anything that looks…

5.5.1.5-testnet

Gridcoin releases

Gridcoin 5.5.1.5 — Testnet Release This is a testnet pre-release covering 157 merged pull requests since 5.5.1.3-testnet (15 June 2026). It is the largest testnet drop in the 5.5.x line, and it is primarily a soak release: a great deal of new machinery is present and ready to be exercised, and no consensus rule changes activate in it. Please run it, use it normally, and report anything that looks wrong. No consensus change activates — and two features are dormant because of it BlockV15Height…
