Documentation

• scope D2e-M2 FTS5 sqlite-compat to unicode61-matching text (tokenizer gap)
• (roadmap) audit VDBE (B5c) coverage and note the param-less foundation
• (roadmap) B1b — graphite's join planner diverges from sqlite by design
• (roadmap) B4 sqlite_stat4 is blocked by the differential oracle
• README — FTS5 files are now byte-compatible with sqlite
• mark D2e-M1 (read sqlite FTS5) done in ROADMAP
• mark D3c (R-Tree on-disk node format) done in ROADMAP and README
• README notes the VDBE is now the default SELECT engine
• record VDBE pure scalar function support in ROADMAP
• record VDBE spike scalar-expression coverage in ROADMAP
• record snippet() auto-column + spaced-colon fix in ROADMAP

Fixed

• (fts5) fold Latin-1 diacritics in the tokenizer to match unicode61
• (parser) number anonymous ? parameters by parse position, not eval order
• (datetime) unixepoch(X, 'subsec') returns fractional seconds
• (alter) RENAME COLUMN propagates into multi-source trigger bodies
• (json) propagate JSON subtype through aggregates, multi-path extract, and ->
• (parser) allow OFFSET and END as bare column names
• (pragma) journal_mode reports "memory" for an in-memory database
• (create) reject CHECK/generated expressions referencing unknown columns
• (drop) DROP ... IF EXISTS still rejects a wrong-type object
• (alter) RENAME TABLE rewrites dependent trigger bodies
• (vdbe) harden opt-in routing (grouped bare columns, schema, collation, labels)
• (json) json_quote returns a JSON-subtyped argument unquoted
• (pragma) foreign_key_list lists foreign keys by id ascending
• (update) SET subqueries see the pre-update snapshot
• (json) json_set/json_insert create intermediate containers
• (parser) reject a numeric literal followed by an identifier character
• (rtree) reject a duplicate id, the rowid-alias column
• (vtab) reject an explicit duplicate rowid on a persistent vtab INSERT
• (fts5) accept whitespace around the col : token column filter
• (alter) RENAME COLUMN preserves CREATE text — A-rn4 complete
• (alter) DROP COLUMN preserves CREATE text like sqlite (A-rn4)
• (alter) ADD COLUMN appends verbatim text to the schema (A-rn4)
• (alter) RENAME TO preserves CREATE text like sqlite (A-rn4)
• (constraint) CHECK violation names the constraint, like sqlite
• (constraint) UNIQUE message names columns on WITHOUT ROWID too
• (constraint) UNIQUE violation names the offending columns

Performance

• (planner) seek by rowid for the rowid/rowid/oid keyword aliases
