Paint.NET（ペイントドットネット）

Version 4.2.13 （2020/08/05）

• New: Added 2-bit per pixel support when saving as PNG
• New: Added 1-bit per pixel support when saving as PNG, BMP, and TIFF
• Fixed low-bit-depth saving quality (8-bit, etc.), as it would sometimes produce very bad results (e.g. only using 64 colors instead of 256)
• Fixed: Resizing an image at very large sizes (e.g. 32K pixels to 64K pixels) would fail due to an arithmetic overflow
• Fixed: Sometimes recently saved images would not have an updated thumbnail in File Explorer unless/until its window was manually refreshed
• Fixed: Sometimes saving an image to a network share would not work
• Updated bundled DDSFileTypePlus plugin to version 1.10.4.0, which fixes an issue when loading and saving images using the sRGB color space. This issue was reported here: https://forums.getpaint.net/topic/116572-dds-file-format-bc1-bc7-srgb-export-incorrectly . Thanks @null54!

Version 4.2.12 （2020/05/30）

• Fixed an error that was preventing some old PDN images from loading (reported here: https://forums.getpaint.net/topic/116501-error-opening-older-pdn-files/)
• Fixed a crash in the new selection outline renderer (due to misaligned Push/PopAxisAlignedClip calls)
• Changed saving to use the ReplaceFile Win32 API, which improves its compatibility
• Fixed an EndOfStreamException error that prevented some JPEGs from opening (thanks @null54 for the fix!)

Version 4.2.11 （2020/05/21）

• Fixed: "Open Containing Folder" now selects the item in the Explorer window
• Fixed: Saving with the HEIC file type is no longer limited to a max Quality value of 90. This limitation was in place because of a crash due to heap corruption, which no longer happens.
• Fixed a bug where the selection would disappear forever if the canvas was scrolled away from it
• Fixed errors when trying to save into certain cloud-sync'd folders, e.g. OneDrive for Business. This was done by disabling the use of NTFS Transactions.
