+### Changed
+
+- The compliance suite is [toml-test](https://github.com/toml-lang/toml-test)
+  v2.2.0, run in TOML 1.0 mode. The new corpus holds 205 valid and 474 invalid
+  cases (v1.6.0 had 185 and 371), and it caught the two documents the parser
+  still accepted, fixed below.

 ### Fixed
 
+- A float with an exponent marker but no digits (`1e`, `0.0E`) is rejected;
+  the exponent requires at least one digit.
+- A date-time offset outside 00:00 through 23:59 is rejected; such offsets
+  were accepted and silently rolled over (`+00:60` decoded as `+01:00`).
 - Untagged embedded fields now decode symmetrically with encode: an embedded
   struct receives its keys inline (a nil embedded pointer struct is
   allocated), an embedded map catches the keys no field claims, and a name
