更新内容
改进
-
Performance improvements for parsing HTML on Android, of 1.5x to 1.9x, with larger parses getting a bigger speed increase. For non-Android JREs, around 1.1x to 1.2x.
-
Dramatic performance improvement in HTML serialization on Android (KitKat and later), of 115x.
-
Improvement by working around a character set encoding speed regression in Android.
-
Performance improvement for the class name selector on Android (.class) of 2.5x to 14x. Around 1.2x on non-Android JREs.
-
File upload support. Added the ability to specify input streams for POST data, which will upload content in MIME multipart/form-data encoding.
-
Add a meta-charset element to documents when setting the character set, so that the document's charset is unambiguous.
-
Added ability to disable TLS (SSL) certificate validation. Helpful if you're hitting a host with a bad cert, or your JDK doesn't support SNI.

Added ability to further tweak the canned Cleaner Whitelists by removing existing settings.
-
Added option in Cleaner Whitelist to allow linking to in-page anchors (#)
Use a lowercase doctype tag for HTML5 documents.

-
Added support for HTTP method verbs PUT, DELETE, and PATCH.
-
Added support for overriding the default POST character of UTF-8 in Connection.
-
W3C DOM support: added ability to convert from a jsoup document to a W3C document, with the W3CDom helper class.

In the HtmlToPlainText example program, added the ability to filter using a CSS selector. Also clarified the usage documentation.

Improved the equals() and hashcode() methods in Node, to consider all their child content, for DOM tree comparisons.
-
Improved performance in Selector when searching multiple roots.
Bug 修复

Fixed an issue where submitting a form would incorrectly include radio and checkbox values without the checked attribute.
-
Fixed an issue where Element.classNames() would return a set containing an empty class; and may have extraneous whitespace.
-
Fixed an issue where attributes selected by value were not correctly space normalized.
In head+noscript elements, treat content as character data, instead of jumping out of head parsing.
-
Fixed performance issue when parsing HTML with elements with many children that need re-parenting.
-
Fixed an issue where a server returning an unsupport character set response would cause a runtime
-
UnsupportedCharsetException, instead of falling back to the default UTF-8 charset.
