jsoup 1.9.1 发布。

更新日志：

改进：

• Added support for HTTP and SOCKS request proxies, specifiable per connection. See Connection.proxy(String, int).

• Added support for sending plain HTTP request bodies in POST and PUT requests, with Connection.requestBody(String).

• Added support in Jsoup.Connect() for HEAD, OPTIONS, and TRACE.

• Added support for HTTP 307 Temporary Redirect (replays posts, if applicable).

• Performance improvements when parsing HTML, particularly on Android Dalvik.

• Added support for writing HTML into Appendable objects (like OutputStreamWriter), to enable stream serialization. See Node.html(T)

• Added support for XML namespaces when converting jsoup documents to W3C documents.

• Added support for UTF-16 and UTF-32 character set detection from byte-order-marks (BOM).

• Added support for tags with non-ascii (unicode) letters.

• Added Connection.data(String) to retrieve a data KeyVal by its key. Useful to update form data before submission.

Bug 修复

• Fixed an issue in the Parent selector where it would not match against the root element it was applied to.

• Fix an issue where Elements.select(String) would not return every matching element if they had the same content.

• Added not-null validators to Element.appendText() and Element.prependText()

• Fixed an issue when moving moving nodes using Element.insert(int, Collection) where the sibling index would be set incorrectly, leading to the original loads being lost.

• Reverted Node.equals() and Node.hashCode() back to identity (object) comparisons, as deep content inspection had negative performance impacts and hashkey stability problems. Functionality replaced with Node.hasSameValue().

• In Connection, if the same header key is seen multiple times, combine their values with a comma per the HTTP RFC, instead of keeping just one value. Also fixes an issue where header values could be out of order.
