ISArcEx v0.5 — Update 02 (LibOnly)

Bug fixes only. No API changes.

Fixed Issues:

• ISArcExReduceCalcAccuracy did not perform as expected in v0.5 due to an internal architectural change introduced in this version. This has been corrected and the function now behaves as intended again.

• ISArcExCallbackInterval silently ignored some values, causing progress updates to appear sluggish or unresponsive regardless of the configured interval. The valid input range has been restored.

• State inconsistency where accuracy reduction settings could behave unpredictably across multiple init calls in the same session.

Notes:

• Drop-in library replacement. No script-side changes required.
