Unit changes

FPCanvas Strikethough property spelling fixed to StrikeThrough

• Old behaviour: Fonts had a Striketrough property which is a typo.
• New behaviour: The property has been changed to Strikethrough.
• Reason: Spelling fix.
• Remedy: Please rename property calls in your code. FPC 2.6.2 contains both versions so there is a window for adaptation.

shlobj symbols removed from unit Windows

• Old behaviour: When unit windows was split between the windows and shlobj units, not all shlobj symbols were removed from Windows.
• New behaviour:
  • Now: the symbols are marked deprecated in the windows unit.
  • Next major version: shlobj symbols will be removed from the windows unit. Code relying on that will fail to compile if it doesn't import shlobj.
• Reason: shlobj and windows versions were not compatible and lead to errors.
• Remedy: put shlobj in your uses, if not there already.
