-Enhancement: Check now checks index when reading packs
+Enhancement: Check now has more checks for consistency of index and pack files
 
-Restic used to only verfiy the pack file content when calling `check --read-data`
+Restic used to only verify the pack file content when calling `check --read-data` or
 `check --read-data-subset` but did not check if the blobs within the pack are
 correctly contained in the index.
-This check is now added and may give an "Blob ID is not contained in index" error.
+This check is now added and may give an "Blob ID is not contained in index or position
+is incorrect" error.
+Also a new test is added which compares pack file sizes computed from the index and the
+pack header with the actual file size. This test is able to detect truncated pack files.
+
 If the index is not correct, it can be rebuilt by using the `rebuild-index` command.
 
+Having added these tests, `restic check` is now able to detect non-existing blobs which
+are wrongly referenced in the index. This situation could have lead to missing data.
