Documents the transaction starting timestamp exposed to procedures. The value stays stable across USING PERIODIC COMMIT boundaries, making it usable as a per-query cache key. Pairs with memgraph/memgraph#4167.
…#1627) Add the two new columns to the schema table and example outputs, note that snapshot rows now populate them at the top level, and update the snapshot-progress callout to mention the brief window where start_time can read as null.
* docs(schema): document expanded output of schema type-properties procedures Update the Output, Usage, and Example sections of schema.node_type_properties and schema.rel_type_properties to describe the new sourceNodeLabels, targetNodeLabels, propertyObservations, and totalObservations columns and the (relType, sourceNodeLabels, targetNodeLabels) partitioning for the rel-properties procedure. Replace example result tables with output captured against the updated procedures. * docs(schema): fix Kept key value in schema.assert example The Kept row of the schema.assert example showed "id" for a unique constraint on a single property, but the procedure emits "[id]" (the stringified property list) for that action.
Add the cross_database reference page covering all procedures (bolt, neo4j, mysql, postgresql, sql_server, oracle_db, s3, arrow_flight, duckdb, servicenow), the Bolt type conversion rules (including the lossy 30-days-per-month Duration flattening), the same-parameters guard, and the migrate.* alias table. Reduce the migrate page to a redirect stub pointing at cross_database; the migrate.* names continue to work via Memgraph's callable-mapping aliases, but the canonical reference now lives at cross_database.
* feat: Intra-cluster TLS * docs: Document charts-side of the reload feature
* update ddebugging page * update direct download links * update debugging page
* feat: document elementId function * docs: trim elementId description to mirror id()
…n files (#1661) Rewrite the Session trace section to reflect memgraph#4149: --query-log-directory and per-session {uuid}.log files are removed; SET SESSION TRACE ON now emits tagged [session=<uuid>] events into the main log at INFO (visible when --log-level is INFO or lower). Remove the --query-log-directory configuration flag row.

* feat: document virtual graphs via derive() Document the derive() aggregation function for building in-query virtual (derived) graphs, covering the concept, options (virtualEdgeType, relationshipProperties, source/target node label and property overlays, undirectedEdgeTypes), per-key node inheritance, and usage examples in run-algorithms. Add derive() to the graph projection functions reference. * Remove version note from derive() functions reference entry
Document the new vector index DDL shapes (single, any '|', all '&', and wildcard) for both CREATE VECTOR INDEX and CREATE VECTOR EDGE INDEX, the edge '&' rejection, overlapping-index behavior, and how each mode renders in SHOW INDEX INFO. Update the SHOW VECTOR INDEX INFO label field description and refresh the walkthrough outputs for the new :Label display.
* feat: document fuzzy text search and the search config map Document the new optional config map for the text_search search and regex_search procedures (limit plus fuzzy_distance, fuzzy_prefix and fuzzy_transpositions), add a dedicated Fuzzy search section with examples, and note that limit moved from a positional argument into the config map. * docs: remove nonexistent limit param from text_search.aggregate text_search.aggregate / aggregate_edges take (index_name, search_query, aggregation_query); there is no limit argument.

It contains confirmed documentation inaccuracies/inconsistencies (notably incorrect CLI flag spellings and misleading vector-index semantics) that should be corrected before merging.
Pull request overview
Updates the documentation site for the Memgraph v3.11.0 release by adding the new release-notes section and propagating the associated product changes across reference, guides, and operational docs (metrics/storage info semantics, cross-database migration module rename, new conversion functions, TLS reload privilege, etc.).
Changes:
- Added Memgraph/Lab v3.11.0 release notes and updated direct download links.
- Refreshed multiple docs pages to reflect 3.11 breaking changes and new features (storage info scoping, logging, metrics, vector/text search enhancements, schema procedure outputs, HA TLS options, etc.).
- Introduced/updated internal skills guidance for release/changelog workflows (ordering rules, implementation tips).

| `--log_failed_queries`, and `--log_query_plan`, or override per session via | ||
| `SET SESSION SETTING` for those keys (optional EXPLAIN plan on slow queries). |
