Featured in Kotlin Weekly #535 (November 1, 2026): offline KMP reminder walkthrough.

Buy milk tomorrow at 7pm → Buy milk + tomorrow at 19:00.

Use it in commonMain with a reference instant, an explicit timezone and US/European date order. The runnable KMP consumer and Android Compose demo show how to review and edit the result before saving. No API keys or network calls.

• DateParser Kotlin: cross-platform parsing and CI - offline date parsing, explicit time semantics, Maven publishing and independent JVM/Android/iOS checks.
• Kotlin CSV: UTF-8 corruption at a buffer boundary - a minimal surrogate-pair regression, focused fix and test coverage.
• Telegram callback handling - API compatibility and dispatch regressions for game callbacks.

• awesome-kotlin #1204 - added DateParser Kotlin to the curated library catalogue (merged October 30, 2026; catalogue entry, not a code change).
• fast-compose #2 - preserved mixed named and positional argument order throughout the Kotlin/Compose interpreter (merged November 3, 2026; 19 focused regressions).
• nemo-editor #38 - preserved Kotlin identifiers that begin with keywords in the formatter (merged November 3, 2026).
• biweekly #136 - used a 24-hour clock for timezone observance boundaries (merged November 3, 2026).

Other engineering changes and their current review status are documented in the upstream contribution log. Open and draft PRs are not listed as accepted work.

A chat-shaped planner: tasks, notes, folders and a calendar in one place.
