==Whitespaces==
The notorious {{Code|CHOP}} option was removed to prevent conflicting behavior caused by earlier installations. It was replaced by a new {{Option|STRIPWS}} option, which defaults to {{Code|false}}. In addition, the new default of the [[Serialization|serialization parameter]] {{Code|indent}} is {{Code|no}}.
The [[Transaction_Management|transaction manager]] gathers the names of the databases that will be accessed by a query. If it is not possible to uniquely identify all databases that may be opened by the query, global locking will be applied, and all databases will be locked. Detection can fail if the names of databases depend on external input. It can also fail if a query is too complex to associate character strings with database operations.
# ''Compilation'' of logical, context-independent operations. External values are bound to the query, and deterministic code is rewritten, simplified and pre-evaluated.
