Ollama v0.30.5 fixes gemma4 crash and streamlines Hermes Desktop

Critical crash fix for gemma4:12b on CUDA and Windows, plus Hermes launch improvements

Deep Dive

Ollama released v0.30.5 on June 4, addressing a critical floating-point exception crash in the gemma4:12b model on x86 systems with CUDA, Linux, and Windows. This fix resolves a common crash that prevented users from running the model reliably on local hardware. The update also enhances the Hermes Desktop experience: the `ollama launch hermes-desktop` command now skips rebuilding if a packaged desktop app is already installed, saving time during repeated launches. Additionally, `ollama launch hermes` now supports native Windows installations through a PowerShell installer, making it easier for Windows users to get started with Hermes without manual workarounds.

Beyond Hermes improvements, this release adds documentation for Cline CLI integration, expanding Ollama's ecosystem compatibility. The full changelog from v0.30.4 to v0.30.5 includes these three targeted fixes and enhancements. With over 173,000 stars on GitHub and 23 reactions on the release, the update is well-received by the community. For developers running local LLMs, this patch eliminates a key stability blocker for gemma4:12b and streamlines the deployment of Hermes Desktop across platforms.
