   - Set the value to an empty string only when all LibreChat credentials are injected through other supported environment settings
   - Bundled Meilisearch still requires its separately configured master-key Secret
 
+- Added optional saved-chat workspace transitions after rc4
+  - `endpoints.agents.statefulCodeSessions.conversationMoves.enabled` opts in to moving a conversation's sealed workspace and recovering a missing workspace
+  - `conversationMoves.allowAttachDetach` separately opts in to attaching or leaving a workspace; omission keeps the move-only policy
+  - Upgrade every API replica and enable `CODE_ENVIRONMENT_DECISION_VERSION=1` before activating the transitions
+
+- Added optional attached-workspace request budgets
+  - `statefulCodeSessions.environments[].configSchema.limits.maxRequestTimeoutMs` caps total HTTP time for one call at up to `610000` ms
+  - The existing 30-second admission budget per attempt remains when this is unset, and `maxQueueWaitMs` remains an independent retry horizon
+  - Do not enable longer admission until the Code API honors per-request queue allowances and the shortest live ingress timeout has been measured
+  - `configSchema.limits.minCommandAdmissionMs` reserves `10000` ms by default before command execution (valid `1000`–`300000` ms); the total request budget must exceed this reserve plus 10000 ms of settlement/delivery grace
+  - Configured and advertised Bash command limits fit within the remaining HTTP budget; a 90000 ms request with an 80000 ms command ceiling and default reserve advertises at most a 70000 ms command
+
+- Added opt-in linked-worktree scheduling for attached Code environments
+  - `statefulCodeSessions.environments[].configSchema.workspaces.linkedWorktrees` defaults to off; enable only after upgrading LibreChat, deploying Code API linked-worktree support, and starting compatible workers with `--linked-worktree-lanes`
+  - File tools with a worktree path and Bash commands with a worktree `cwd` use that worker lane; commands that `cd` internally stay in the checkout lane
+
+- Added idle Agent recovery and graceful-shutdown controls
+  - `endpoints.agents.eventDriven.idlePolling.deliveryMaxIntervalMs` defaults to `15000` ms
+  - `queuedTurnMaxIntervalMs` and `maintenanceMaxIntervalMs` default to `120000` ms; `completionWaitMaxIntervalMs` defaults to `60000` ms
+  - Local readiness events can expedite delivery without waiting for an idle MongoDB recovery scan
+  - `endpoints.agents.backgroundTasks.shutdownInterruptGraceMs` defaults to `5000` ms (valid `0` through `60000`) before unfinished tools are recorded as interrupted during graceful shutdown
+
+- Added `interface.agentSelectorLimit` to cap the unsearched Agent selector at `10` entries by default (valid `1` through `100`); searching still reaches all Agents
+
+- Updated configuration validation and reload behavior
+  - Malformed explicitly configured `CREDS_KEY` or `CREDS_IV` values now fail startup; migrate data encrypted with an invalid-length key deliberately rather than rotating it blindly
+  - `rateLimits.conversationsImport`, `rateLimits.tts`, `rateLimits.stt`, and skill/Agent upload limits from `librechat.yaml` now apply to their route limiters without matching environment variables
+  - Invalid role, group, or user config override writes now return `400` without saving; previously stored overrides that would invalidate the merged config are dropped with a warning
+  - Reload failures keep the last good validated configuration active; startup validation still fails closed
+
+- Hardened MCP OAuth HTTP requests
+  - Server-side OAuth discovery, registration, token, and revocation calls reject redirects; configure the final URL when an identity provider redirects
+  - Private IP literals are refused unless permitted by the existing admin-trusted host or exact address-and-port policy
+
+- Added capability-negotiated workspace edit matching
+  - `statefulCodeSessions.environments[].configSchema.edits.tolerantMatching` allows whitespace-tolerant fallback by default when the worker advertises `tolerant_match`; set it to `false` to require exact matches
+  - Attached `edit_file` and protected edit previews only send new matching fields after negotiation; `replace_all` also requires the worker to advertise that feature
+  - Requires compatible Code API and worker builds implementing [Code Interpreter #271](https://github.com/LibreChat-AI/code-interpreter/pull/271); older deployments keep their current request format and matching behavior
+  - Edit conflicts use bounded, host-rendered facts rather than untrusted worker text; a rejected batch writes nothing
+
+- Added GPT point-release family fallback and GPT-6.1 Sol
+  - A GPT point release without its own entry inherits the recognized family's context/output limits, pricing, and reasoning settings; explicit per-release entries win
+  - GPT-6.1 Sol joins the OpenAI and Agents catalogs, not Assistants; its limits and prices currently inherit GPT-6 Sol rather than new provider-published figures
+  - Native OpenAI Responses routing can inherit the family policy; Azure deployment routing and custom-endpoint opt-in behavior stay unchanged
+
+- Hardened web-search credential pairing
+  - User-provided Firecrawl or SearXNG URLs cannot be combined with the server's API key, even when the destination passes SSRF checks
+  - Firecrawl ignores the optional user URL and uses its default endpoint; SearXNG cannot initialize with that mixed-ownership pair because its URL is required
+  - User-owned pairs, administrator-owned pairs, and keyless SearXNG remain supported; set both URL and key at the same ownership level
+
+- Added tenant-scoped YAML custom endpoints
+  - `endpoints.custom[].tenantId` optionally restricts an endpoint and its associated model specs to the authoritative request tenant; omission preserves deployment-wide availability
+  - Tenant IDs accept 1–128 letters, digits, hyphens, underscores, or periods; whitespace and the reserved `__SYSTEM__` sentinel are invalid
+  - Missing tenant context does not receive scoped endpoints; cache, override, runtime augmentation, and fallback paths keep the same boundary
+  - Filtering the last model spec restores normal model controls while preserving explicit interface settings
+  - Upgrade every API replica before configuring scoped endpoints; older replicas do not enforce the new YAML field
+
+- Bound per-user MCP API keys to their destinations
+  - UI-created/shared servers require each user to enter a key again when the URL path/query, proxy, transport, auth format/header, or configured OAuth client/destination changes
+  - Equivalent and cosmetic updates preserve existing keys; legacy keys remain usable at their unchanged boundary without a bulk migration
+  - Shared servers resolve only their currently declared credential variables, so old generated names cannot bypass re-entry
+  - Upgrade every API replica, including configuration writers, before relying on the new binding
+
 - Updated the config version to `1.3.17`
