Updated the CHANGELOG so it's easier when 4.0 is actually released
2016-08-27 02:46:17 +08:00
## [4.0.0 - In progress](https://github.com/rs/SDWebImage/tree/4.x)
#### Infrastructure:
- support for **watchOS** and **OS X** platforms #1595
- the `SDWebImage xcodeproj` contains the following targets:
- `SDWebImage iOS static` (iOS static lib)
- `SDWebImage watchOS static` (watchOS static lib)
- `SDWebImage OSX` (OSX dynamic framework)
- `SDWebImage iOS` (iOS dynamic framework)
- `SDWebImage tvOS` (tvOS dynamic framework)
- `SDWebImage watchOS` (watchOS dynamic framework)
- the `SDWebImage Demo xcodeproj` contains the following targets:
- `SDWebImage OSX Demo`
- `SDWebImage iOS Demo`
- `SDWebImage TV Demo`
- `SDWebImage Watch Demo`
- bumped `libwep` version to `0.5.0`
#### Backwards incompatible changes
- removed all deprecated methods (that we carried around for backwards compatibility in previous versions) #774
- Renamed `SDWebImageManager` `downloadImageWithURL:options:progress:completed:` to `loadImageWithURL:options:progress:completed:` as it makes more sense, since we check the cache first and download only if needed a32a177
- Deleted targets: `SDWebImage+MKAnnotation`, `SDWebImage+WebP`, `SDWebImageFramework`:
- `SDWebImage `target that build as a static library (all subspecs included) -> `libSDWebImage.a`
- `SDWebImageiOS` and `SDWebImagetvOS` targets that build as dynamic frameworks
- Renamed the dynamic frameworks targets from `WebImage` to `SDWebImage`. Renamed the `WebImage.h` to `SDWebImage.h` to match the framework naming
- Renamed the schemes for consistency. Updated the Tests Podfile + project.
- For #883 Fix multiple requests for same image and then canceling one, several breaking changes were needed:
- `SDWebImageDownloader` method `- downloadImageWithURL:options:progress:completed:` now returns a `SDWebImageDownloadToken *` instead of `id <SDWebImageOperation>` (give the ability to cancel downloads using the returned token)
- `SDWebImageDownloaderOperation` initializer `- initWithRequest:options:progress:completed:cancelled` split into `- initWithRequest:options` and `addHandlersForProgress:completed:`. Note: there is no more cancel block
- Modern Objective-C syntax done in 64382b9 includes:
- initializers now return `instancetype` instead of `id`
- explicit designated initializers (i.e. for `SDImageCache`)
- For #1575 GIF support using FLAnimatedImage, several changes were needed:
- replaced type `SDWebImageQueryCompletedBlock` with `SDCacheQueryCompletedBlock` and added an `NSData *` param
- because of the change above, the `done` param of `SDImageCache` `queryDiskCacheForKey:done:` is now a `SDCacheQueryCompletedBlock` and those blocks must now include an `NSData *` param
- replaced type `SDWebImageCompletionWithFinishedBlock` with `SDInternalCompletionBlock` and added an `NSData *` param
- because of the change above, the `completed` param of `SDWebImageManager` `loadImageWithURL:options:progress:completed:` is now `SDInternalCompletionBlock` and those blocks must now include an `NSData *` param
- for consistency with the previous change, also renamed `SDWebImageCompletionBlock` to `SDExternalCompletionBlock`
- `UIImage` will no longer respond to `sd_animatedGIFNamed:` or `sd_animatedImageByScalingAndCroppingToSize:`
- Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581
- breaks compatibility at least for Swift users of the framework
- **watchOS** and **OS X** support #1595 required
- renamed `SDWebImage` iOS static lib target to `SDWebImage iOS static` for clarity
#### Features:
- Switched our GIF support to a better implementation: [FLAnimatedImage by Flipboard](https://github.com/Flipboard/FLAnimatedImage) #1575
- requires iOS 8+ (it's the only way due to FLAnimatedImage requirements)
- the implementation relies on a `WebCache` category on top of `FLAnimatedImageView`
- details in the [README](README.md#animated-images-gif-support)
- Converted any remaining code to Modern Objective-C syntax - 64382b9
- Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581
- via #1595 Clarified and simplified the usage of `TARGET_OS_*` macros. Added `SD_MAC`, `SD_UIKIT`, `SD_IOS`, `SD_TV`, `SD_WATCH`. The biggest issue here was `TARGET_OS_MAC` was 1 for all platforms and we couldn't rely on it.
- Replaces #1398 Allow to customise cache and image downloader instances used with `SDWebImageManager` - added a new initializer (`initWithCache:downloader:`) 9112170
#### Fixes:
- Fix multiple requests for same image and then canceling one #883 + 8a78586
- Fixed #1444 and the master build thanks to [@kenmaz](https://github.com/kenmaz/SDWebImage/commit/5034c334be50765dfe4e97c48bcb74ef64175188)
Bumped version to 3.8.2
2016-09-06 01:11:18 +08:00
## [3.8.2 Patch release for 3.8.0 on Sep 5th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.8.2)
#### Fixes:
- Fixed #1608 #1623 #1644 Crash in `[NSURLCache cachedResponseForRequest:]` - the fix is actually avoiding to access `NSURLCache` which appears to generate a race condition. We only call it if necesarry (`SDWebImageRefreshCached` is used and the image cannot be cached by the system when it's too big or behind authentication)
Updated the CHANGELOG so it's easier when 4.0 is actually released
2016-08-27 02:46:17 +08:00

## [3.8.1 Patch release for 3.8.0 on Jun 7th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.8.1)
#### Fixes:
- SDWebImage 3.8.0 get wrong image #1589 - the issue was caused by the changes in 3.8.0 (Removed the URL query params from the filename (key) fb0cdb6d 1bf62d4 #1584 - fixes #1433 #1553 #1583 #1585) - Reverted.
- Note: The solution for those issues (i.e. #1433 #1553) is to set the `SDWebImageManager` `cacheKeyFilter` block and do their own calculations there.

Reverted all the changes for "Removed the URL query params from the filename (key)" fb0cdb6d 1bf62d4 #1584 - fixes #1433 #1553 #1583 #1585 This is a deal breaker for people. The solution for those issues (i.e. very long urls) is to set the SDWebImageManager cacheKeyFilter block and do their own calculations there.

- Fixed race condition that causes cancellation of one download operation to stop a run loop that is now used for another download operation. Race is introduced through `performSelector:onThread:withObject:waitUntilDone:` - [#698](https://github.com/rs/SDWebImage/pull/698)
- Fixed race condition between operation cancelation and loading finish - [39db378](https://github.com/rs/SDWebImage/commit/39db378) [#621](https://github.com/rs/SDWebImage/pull/621) [#783](https://github.com/rs/SDWebImage/pull/783)
- Fixed race condition in SDWebImageManager if one operation is cancelled - [f080e38](https://github.com/rs/SDWebImage/commit/f080e38) [#699](https://github.com/rs/SDWebImage/pull/699)
- Fixed issue where cancelled operations aren't removed from `runningOperations` - [#68](https://github.com/rs/SDWebImage/issues/68)
- Should not add url to failedURLs when timeout, cancel and so on - [#766](https://github.com/rs/SDWebImage/pull/766) [#707](https://github.com/rs/SDWebImage/issues/707)
- Fixed potential *object mutated while being enumerated* crash - [#727](https://github.com/rs/SDWebImage/pull/727) [#728](https://github.com/rs/SDWebImage/pull/728) (revert a threading fix from [#727](https://github.com/rs/SDWebImage/pull/727))
- Fixed `NSURLConnection` response statusCode not valid (e.g. 404), downloader never stops its runloop and hangs the operation queue - [#735](https://github.com/rs/SDWebImage/pull/735)
- Fixed `SDWebImageRefreshCached` bug for large images - [#744](https://github.com/rs/SDWebImage/pull/744)
- Added proper handling for `SDWebImageDownloaderLowPriority` - [#713](https://github.com/rs/SDWebImage/issues/713) [#745](https://github.com/rs/SDWebImage/issues/745)
- Fixed fixing potential bug when sending a nil url for UIButton+WebCache - [#761](https://github.com/rs/SDWebImage/issues/761) [#763](https://github.com/rs/SDWebImage/pull/763)
- Fixed issue [#529](https://github.com/rs/SDWebImage/pull/529) - if the `cacheKeyFilter` was set, this was ignored when computing the `scaledImageForKey`. For most of the developers that did not set `cacheKeyFilter`, the code will work exactly the same - [eb91fdd](https://github.com/rs/SDWebImage/commit/eb91fdd)
- Returning error in setImage completedBlock if the url was nil. Added `dispatch_main_async_safe` macro - [#505](https://github.com/rs/SDWebImage/issues/505) [af3e4f8](https://github.com/rs/SDWebImage/commit/af3e4f8)
- Avoid premature completion of prefetcher if request fails - [#751](https://github.com/rs/SDWebImage/pull/751)
- Return nil from `SDScaledImageForKey` if the input image is nil - [#365](https://github.com/rs/SDWebImage/issues/365) [#750](https://github.com/rs/SDWebImage/pull/750)
- Do not load placeholder image if `SDWebImageDelayPlaceholder` option specified - [#780](https://github.com/rs/SDWebImage/pull/780)
- Make sure we call the `startPrefetchingAtIndex:` method from main queue - [#694](https://github.com/rs/SDWebImage/pull/694)
- Save image in cache before calling completion block - [#700](https://github.com/rs/SDWebImage/pull/700)
- Fixed arm64 warnings - [#685](https://github.com/rs/SDWebImage/pull/685) [#720](https://github.com/rs/SDWebImage/pull/720) [#721](https://github.com/rs/SDWebImage/pull/721) [#687](https://github.com/rs/SDWebImage/pull/687)
