Old method	Changes to note
Add	Renamed to Zip. No longer takes any parameters. Use the SkipIf* properties to reproduce the Add method's parameters. For example: Before:  Add(xecAll) After: Zip Before: Add(xecFreshen) After: SkipIfNotExisting = True           Zip Before: Add(xecUpdate) After: SkipIfExisting = True           Zip
Delete	Renamed to RemoveFiles.
Extract	Renamed to Unzip. Use the SkipIf* properties to reproduce the Extract method's parameters. See the description for the Add method above for an example.
Fix	This method no longer exists. The new library will unzip everything it can from a corrupted zip file – there's no need to fix and unzip in two separate operations. However, the Convert method will allow you to repair a corrupted zip file if you still need this functionality.
GetFileInfo	This method no longer exists. You get information on a file by using the ListZipContents method and specifying the filename in the FilesToProcess property. The ListingFile event provides you with the info.
List	Renamed to ListZipContents.
MakeSelfExtracting	This method no longer exists. The Convert method allows you to (among other things) perform the same conversion operation. Example: Before: ZipFileName = "this.zip"               SelfExtracting = True               SfxBinary = "xcdsfx32.bin"               MakeSelfExtracting After: ZipFileName = "this.zip"           SfxBinaryModule = "xcdSfx32.bin"           Convert("that.exe")
MemCompress MemOriginalSize MemUncompress StringCompress StringUncompress	The Xceed Compression control object now handles in-memory compression and decompression. Refer to that object for equivalent methods.
SfxResetDefaultStrings	Now divided into three methods called SfxResetButtons, SfxResetMessages and SfxResetStrings.
Test	Renamed to TestZipFile. You can now pass a parameter so you can control whether to test the zip structure only, or the zip structure and the integrity of the compressed data.
UpdateZipDate	This method no longer exists.
