0.21.4

Patch Changes

• #5161 9e42cc2 Thanks @pauldambra! - Make oversized events cheaper to truncate. The depth reduction now starts at the first depth that removes anything, so shallow payloads such as rows of data no longer normalize and measure the whole event again for each depth that changes nothing.

0.21.3

Patch Changes

#5186 80b9e5f Thanks @lucasheriques! - Sanitize only the part of a long string that the captured event can keep, so a tool call returning megabytes of HTML or text no longer blocks the event loop while it is scanned. A 10 MB HTML response now costs about 5 ms to capture instead of 2.7 s. The captured event does not change.
