+# libzip API changes
+
+This file describes changes in the libzip API and how to adapt your
+code for them.
+
+You can define `ZIP_DISABLE_DEPRECATED` before including `<zip.h>` to hide
+prototypes for deprecated functions, to find out about functions that
+might be removed at some point.
+
+## Changed in libzip-1.0
+
+### new type `zip_error_t`
+
+Error information is stored in the newly public type `zip_error_t`. Use
+this to access information about an error, instead of the deprecated
+functions that operated on two ints.
+
+deprecated functions:
+- `zip_error_get_sys_type()`
+- `zip_error_get()`
+- `zip_error_to_str()`
+- `zip_file_error_get()`
+
+See their man pages for instructions on how to replace them.
+
+The most common affected use is `zip_open`. The new recommended usage
+is:
+
+```c
+int err;
+if ((za = zip_open(archive, flags, &err)) == NULL) {
+	zip_error_t error;
+	zip_error_init_with_code(&error, err);
+	fprintf(stderr, "can't open zip archive '%s': %s\n", archive, zip_error_strerror(&error));
+	zip_error_fini(&error);
+}
+```
+
+### more typedefs
+
+The following typedefs have been added for better readability:
+
+```c
+typedef struct zip zip_t;
+typedef struct zip_file zip_file_t;
+typedef struct zip_source zip_source_t;
+typedef struct zip_stat zip_stat_t;
+```
+
+This means you can use "`zip_t`" instead of "`struct zip`", etc.
+
+
+### torrentzip support removed
+
+torrentzip depends on a particular zlib version which is by now quite
+old.
+
+## Changed in libzip-0.11
+
+### new type `zip_flags_t`
+
+The functions which have flags now use the `zip_flags_t` type for this.
+All old flags fit; you need only to adapt code if you were saving flags in a
+local variable. Use `zip_flags_t` for such a variable.
+This affects:
+- `zip_fopen()`
+- `zip_fopen_encrypted()`
+- `zip_fopen_index()`
+- `zip_fopen_index_encrypted()`
+- `zip_get_archive_comment()`
+- `zip_get_archive_flag()`
+- `zip_get_num_entries()`
+- `zip_get_name()`
+- `zip_name_locate()`
+- `zip_set_archive_flag()`
+- `zip_source_zip()`
+- `zip_stat()`
+- `zip_stat_index()`
+
+#### `ZIP_FL_*`, `ZIP_AFL_*`, `ZIP_STAT_*` are now unsigned constants
+
+To match the new `zip_flags_t` type.
+
+#### `zip_add()`, `zip_add_dir()`
+
+These functions were replaced with `zip_file_add()` and `zip_dir_add()`, respectively,
+to add a flags argument.
+
+#### `zip_rename()`, `zip_replace()`
+
+These functions were replaced with `zip_file_rename()` and `zip_file_replace()`,
+respectively, to add a flags argument.
+
+#### `zip_get_file_comment()`
+
+This function was replaced with `zip_file_get_comment()`; one argument was promoted from
+`int` to `zip_uint32_t`, the other is now a `zip_flags_t`.
+
+#### `zip_set_file_comment()`
+
+This function was replaced with `zip_file_set_comment()`; an argument was promoted from
+`int` to `zip_uint16_t`, and a `zip_flags_t` argument was added.
+
+### integer type size changes
+
+Some argument and return values were not the right size or sign.
+
+#### `zip_name_locate()`
+
+The return value was `int`, which can be too small. The function now returns `zip_int64_t`.
+
+
+#### `zip_get_num_entries()`
+
+The return type is now signed, to allow signaling errors.
+
+#### `zip_set_archive_comment()`
+
+The last argument changed from `int` to `zip_uint16_t`.
+
+### extra field handling rewritten
+
+The `zip_get_file_extra()` and `zip_set_file_extra()` functions were removed.
+They only worked on the whole extra field set.
+
+Instead, you can now set, get, count, and delete each extra field separately,
+using the functions:
+- `zip_file_extra_field_delete()`
+- `zip_file_extra_field_delete_by_id()`
+- `zip_file_extra_field_get()`
+- `zip_file_extra_field_get_by_id()`
+- `zip_file_extra_fields_count()`
+- `zip_file_extra_fields_count_by_id()`
+- `zip_file_extra_field_set()`
+
+Please read the corresponding man pages for details.
+
+### new functions
+
+#### `zip_discard()`
+
+The new `zip_discard()` function closes an archive without committing the
+scheduled changes.
+
+#### `zip_set_file_compression()`
+
+The new `zip_set_file_compression()` function allows setting compression
+levels for files.
+
+### argument changes
+
+#### file names
+
+File names arguments are now allowed to be `NULL` to have an empty file name.
+This mostly affects `zip_file_add()`, `zip_dir_add()`, and `zip_file_rename()`.
+
+For `zip_get_name()`, `zip_file_get_comment()`, and `zip_get_archive_comment()`, if
+the file name or comment is empty, a string of length 0 is returned.
+`NULL` is returned for errors only.
+
+Previously, `NULL` was returned for empty/unset file names and comments and
+errors, leaving no way to differentiate between the two.
