- This week’s is not a huge update, but let that not convince you it’s unimportant. They can’t all be red-letter days (or updates), but each day we’re here is a good one. This update is a good one too.

Slack 4.52.155
27 August 2026
Bug fixes
- Nothing major to report this week. Nothing minor to report either, as it turns out. Work is still happening, mind you – it’s just more the sort that happens behind the curtain in between scenes at a play. We’re quietly setting the stage for what’s to come.

Bug fixes
- No big fixes to bring your attention to this week, but rest assured, there will be more in the future. Not that introducing bugs is our aim, of course.
