PEIL since February 2026
Month by month, what was added. Every row carries a date and points to where it is recorded; what we cannot point to is not listed.
The idea: a guide to Amsterdam's waterways that tells you what you pass, and later what is allowed and where the information comes from. Still named Vaarwater.

April and May appear only when the work journal can point to them; an empty month is not a gap but a verifiable rule
Why this page exists
Who it is for
For anyone who wants to know how long PEIL has existed and what was added when. It is the same list we keep to show since when the PEIL name has been in use.
How it is maintained
From the work journal, the software's change history and the list of completed components; one row per month, with a date and a pointer. Updated with every release.
