  - Support non-string values in markdown fields. `NULL` values are now displayed as empty strings, numeric values are displayed as strings, booleans as `true` or `false`, and arrays as lines of text. This avoids the need to cast values to strings in SQL queries.
  - Revert a change introduced in v0.15.0:
     - Re-add the systematic `CAST(? AS TEXT)` around variables, which helps the database know which type it is dealing with in advance. This fixes a regression in 0.15 where some SQLite websites were broken because of missing affinity information. In SQLite `SELECT '1' = 1` returns `false` but `SELECT CAST('1' AS TEXT) = 1` returns `true`.
+ - Fix a bug where [cookie](https://sql.ophir.dev/documentation.sql?component=cookie#component) removal set the cookie value to the empty string instead of removing the cookie completely.
 
 ## 0.15.0 (2023-10-29)
  - New function: [`sqlpage.path`](https://sql.ophir.dev/functions.sql?function=path#function) to get the path of the current page.
