The list includes reasons why these changes have been implemented, and suggestions for how you might adapt your code if you find that previously working code has been adversely affected by these recent changes. | |

| 5 | + | The list of new features that do not break existing code can be found [[FPC New Features 3.2.2|here]]. | |

| 16 | + | ||
| 17 | + | ##### TBufferedFileStream.Seek(0,soBeginning) | |
| 18 | + | ||
| 19 | + | - **Old behaviour**: TBufferedFileStream.Seek(0,soBeginning) returned -1. | |
| 20 | + | - **New behaviour**: Now TBufferedFileStream.Seek(0,soBeginning) returns 0. | |
| 21 | + | - **Reason:** Delphi-compatibility | |
| 22 | + | - **svn**: 48282 | |
| 23 | + | ||
| 24 | + | ##### Fix matching of Boyer-Moore algorithm for periodicity | |
| 25 | + | ||
| 26 | + | - **Old behaviour**: Pattern "abcab" and the text "abcabcabcabcabcabcab" indicates matches at positions 1, 7, and 13. | |
| 27 | + | - **New behaviour**: Now the pattern "abcab" and the text "abcabcabcabcabcabcab" indicates matches at positions 1, 4, 7, 10 and 13. | |
| 28 | + | - **svn**: 48752 | |
| 29 | + | ||
| 30 | + | ##### SeekEof | |
| 31 | + | ||
| 32 | + | - **Old behaviour**: If *SeekEof* did not find the end of the file, it tried to restore the input to its original state/position. | |
| 33 | + | - **New behaviour**: Data consumed by *SeekEof* while looking for the end of the file (such as spaces) will remain consumed. | |
| 34 | + | - **Reason:** improved TP/BP/Delphi compatibility | |
| 35 | + | - **svn**: 46946 | |
| 36 | + | ||
| 37 | + | ### Unit changes | |
| 38 | + | ||
| 39 | + | ## Darwin/iOS | |
| 40 | + | ||
| 41 | + | ### The Darwin targets corresponding to iOS have been renamed to iOS | |
| 42 | + | ||
| 43 | + | - **Old behaviour:** The Darwin/ARM and Darwin/AArch64 (ARM64) targets generated code for iOS running on those architectures. | |
| 44 | + | - **New behaviour:** The Darwin/AArch64 (ARM64) target generates code for macOS running on AArch64. To generate code for iOS, use the new iOS target (-Tios) | |
| 45 | + | - **Reason for change:** The switch of the macOS platform to AArch64 | |
| 46 | + | - **svn**: 45762 | |
