212 available through `Stream.render()` and `Stream.serialize()`. | |

224 treatment as Python code in template expressions, i.e. item and attribute | |
225 access are no longer interchangeable (which was broken in a number of ways | |
226 anyway, see ticket #113). This change does not affect expressions. | |

228 instructions (tickets #113 and #114). | |

240 loader was fixed by adding locking. | |

273 `QName` objects. This is now the responsibility of whoever is instantiating | |
274 `Attrs` objects (for example, stream filters and generators). | |
275 * Python code blocks are now supported using the `<?python ?>` processing | |
276 instruction (ticket #84). | |
277 * The way errors in template expressions are handled can now be configured. The | |
278 option `LenientLookup` provides the same forgiving mode used in previous | |
279 Genshi versions, while `StrictLookup` raises exceptions when undefined | |
280 variables or members are accessed. The lenient mode is still the default in | |
281 this version, but that may change in the future. (ticket #88) | |
282 * If a variable is not necessarily defined at the top level of the template | |
283 data, the new built-in functions `defined(key)` and `value_of(key, default)` | |
284 can be used so that the template also works in strict lookup mode. These | |
285 functions were previously only available when using Genshi via the template | |
286 engine plugin (for compatibility with Kid). | |
287 * `style` attributes are no longer allowed by the `HTMLSanitizer` by default. | |
288 If they are explicitly added to the set of safe attributes, any unicode | |
289 escapes in the attribute value are now handled properly. | |
290 * Namespace declarations on conditional elements (for example using a `py:if` | |
291 directive`) are no longer moved to the following element when the element | |
292 originally carrying the declaration is removed from the stream (ticket #107). | |
293 * Added basic built-in support for internationalizing templates by providing | |
294 a new `Translator` class that can both extract localizable strings from a | |
295 stream, and replace those strings with their localizations at render time. | |
296 The code for this was largely taken from previous work done by Matt Good | |
297 and David Fraser. | |

311 * Fix XPath traversal in match templates. Previously, `div/p` would be treated | |
312 the same as `div//p`, i.e. it would match all descendants and not just the | |
313 immediate children. | |
314 * Preserve whitespace in HTML `<pre>` elements also when they contain child | |
315 elements. | |
316 * Match templates no longer match their own output (ticket #77). | |
317 * Blank lines before directives in text templates are now preserved as | |
318 expected (ticket #62). | |
