v1.4.0 — OpenCode V2 support and native memory controls

STM 1.4 adds OpenCode V2 support alongside V1, native memory controls, and more reliable memory updates and reset behavior.

Highlights

• OpenCode V2 support: background updates, clean/active summarization, explicit memory models, both delivery modes, child-memory snapshots and compaction integration.
• Native /stm menu on both versions: navigable results for memory, status and settings; confirmed reset and optional example configuration. Read actions bypass the chat model; Update uses the memory model.
• Dedicated memory tools: seven stm_memory_* tools, with the short_term_memory compatibility tool retained.
• Automatic configuration: supported global and local installations create minimal stm.json on first activation, preserving existing settings. No separate setup step is required.

Changes and fixes

• Session-message delivery is now the default. Periodic reminders do not rewrite the system prefix or request an assistant reply. System/context delivery remains optional in clean mode.
• Model selection follows OpenCode defaults. Blank memoryModel uses the fresh-session default in clean mode or the conversation model in active mode. Explicit overrides work in either mode; the hardcoded free-model default is removed.
• Logs returns the log-file path, keeping log contents out of dialogs and model responses.
• Reset starts a new memory period: persistent history boundaries and stale-update fencing prevent background generation from restoring pre-reset memory.
• More reliable updates: improved checkpoint/write-failure handling, preservation of concurrent memory edits, internal STM traffic filtering, temporary-session cleanup and actionable provider errors.
• Safer diagnostics: omit prompt/memory dumps, redact recognized credentials and apply compatible dependency security patches.

Upgrading

Restart OpenCode after upgrading and select the bare /stm command from native autocomplete. Use its menu rather than /stm show or /stm-cmd. Existing STM configuration is preserved.

See the README for V1/V2 installation instructions and the configuration guide for defaults and paths.
