This time I'm going to start by simply reporting everything that is new and changed in these headers, so that others can see the changes more easily. Only public symbols. I'll throw in my own observations along the way.
HEADERS REVIEWED mod_authz_svn.h - no change mod_dav_svn.h - no significant change svn_auth.h svn_base64.h - no change svn_cache_config.h - new header svn_checksum.h svn_client.h - not detailed here; main points in separate email svn_cmdline.h - no change svn_compat.h - no change svn_config.h svn_ctype.h - no change svn_dav.h svn_delta.h svn_diff.h svn_dirent_uri.h svn_dso.h - no change svn_error.h svn_error_codes.h svn_fs.h svn_hash.h NEW AND CHANGED SYMBOLS svn_auth.h svn_auth_open() - gets a 'const' on its 'providers' array input. svn_cache_config.h # Why is the cache config header separate from the cache header? svn_cache_config_t svn_get_cache_config() svn_set_cache_config() # Rename these two to svn_cache_config_*(). svn_checksum.h svn_checksum_kind_t - gets an enum tag name to match typedef. svn_checksum_to_cstring() - new behaviour for null input. svn_checksum_serialize() svn_checksum_deserialize() svn_checksum_mismatch_err() # Make this private, as it's not general-purpose enough? svn_config.h SVN_CONFIG_OPTION_DIFF_EXTENSIONS "diff-extensions" SVN_CONFIG_OPTION_FORCE_USERNAME_CASE "force-username-case" # These two need @since. svn_config_create() svn_config_read2() svn_dav.h SVN_SKEL_MIME_TYPE "application/vnd.svn-skel" # Need @since.
