PyneCore v6.10.8 released — stricter library and request.security validation,…

October 8, 2026

Fixes

Library exports can no longer capture non-constant main() state. Imported libraries’ main() no longer creates drawings or fires alert()
request.security: missing bool results get a proper bool na default, replicas reuse the main script’s resolved inputs, and drawing constructors in request expressions are rejected
plot, plotshape, fill, bgcolor and other declarations outside the unconditional main() body now raise a source-located SyntaxError at transform time
timeframe.change() without an argument now uses the chart timeframe
Module constants are now folded inside functions with exact values and Pine types preserved
Live trading: a market-closed reject (session pause, maintenance) is no longer fatal; the order is re-evaluated when trading resumes
Live trading: rotated restart entries are adopted, reversal close settle timing is honored, and spot inventory quarantine waits for in-flight fills
CCXT: transient candle download errors are retried with backoff

Performance

Optional native color.new in the platform wheels
Cached timestamp components and strategy.close() call sites
Plot metadata cache shared across visualization readers, with the new collect_meta_changes(cursor) API
