itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml
The template language STL has seen the most important change since its inception. A new method for variable substitution has been implemented, it replaces "stl:attributes" and "stl:content". To illustrate this change, while before we wrote: <a stl:attributes="href object_uri" stl:content="object_title" /> Now we will write: <a href="${object_uri}">${object_title}</a> This new approach produces more compact and readable templates. It will also make easier to build some user interfaces. And will help translators since the messages extracted from the templates will be more easy to read. This release is also the first to include some C code. We have rewritten the XML parser ("itools.xml.parser") in C for performance. The programming interface is mostly the same (see the UGRADE.txt file for the incompatible changes). For those who wonder... Why yet-another-xml-parser? Because its programming interface is much much simpler (that means better) than the parsers based in back-calls. See the itools documentation to know more [1]. The other big changes in this release are in "itools.cms", one is for disk usage, the other is functional. The code that implements transactions has been rewritten. From a brute force technique we have moved to a refined one that takes advantage of the extensibility of the "itools.vfs" layer. The visibile change is that we don't need anymore a backup database, so the size of an instance has been reduced to (almost) the half. The functional change has to do with user management. Now we use the email address to identify users, instead of a username. The user must confirm the registration sending an email, this way the application can be certain the email address is valid. There have been also some smaller improvements to the programming interface of other packages, most notably "itools.vfs", "itools.catalog", "itools.web" and "itools.cms". See the file UPGRADE.txt file for the incompatible changes.
