3 = KEY ====================
7 ==========================
9 2.1 release [Refactor, refactor!]
10 # URI validation routines tighter (see docs/dev-code-quality.html) (COMPLEX)
11 # Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
13 - Configuration profiles: predefined directives set with one func call
14 - Implement IDREF support (harder than it seems, since you cannot have
15 IDREFs to non-existent IDs)
16 - Allow non-ASCII characters in font names
18 2.2 release [Error'ed]
19 # Error logging for filtering/cleanup procedures
20 - XSS-attempt detection
22 2.3 release [Do What I Mean, Not What I Say]
23 # Additional support for poorly written HTML
24 - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
25 - Friendly strict handling of <address> (block -> <br>)
26 - Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
27 1. Analyzing which tags to remove duplicants
28 2. Ensure attributes are merged into the parent tag
29 3. Extend the tag exclusion system to specify whether or not the
30 contents should be dropped or not (currently, there's code that could do
31 something like this if it didn't drop the inner text too.)
32 - Remove <span> tags that don't do anything (no attributes)
33 - Remove empty inline tags<i></i>
34 - Append something to duplicate IDs so they're still usable (impl. note: the
35 dupe detector would also need to detect the suffix as well)
37 2.4 release [It's All About Trust] (floating)
38 # Implement untrusted, dangerous elements/attributes
40 3.0 release [Beyond HTML]
41 # Legit token based CSS parsing (will require revamping almost every

45 # Formatters for plaintext
47 - Standardize token armor for all areas of processing
48 - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
49 - Automatically add non-breaking spaces to empty table cells when
50 empty-cells:show is applied to have compatibility with Internet Explorer

52 Also, enable disabling of directionality
54 4.0 release [To XML and Beyond]
55 - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
56 - Hooks for adding custom processors to custom namespaced tags and
57 attributes, offer default implementation
58 - Lots of documentation and samples
61 - Lots of profiling, make it faster!
62 - Plugins for major CMSes (COMPLEX)
63 - WordPress (mostly written, needs beta-testing)
67 - more! (look for ones that use WYSIWYGs)
68 - Complete basic smoketests
70 Unknown release (on a scratch-an-itch basis)
71 ? Semi-lossy dumb alternate character encoding transfor
72 ? Have 'lang' attribute be checked against official lists, achieved by
73 encoding all characters that have string entity equivalents
74 - Explain how to use HTML Purifier in non-PHP languages / create
75 a simple command line stub
76 - Abstract ChildDef_BlockQuote to work with all elements that only
77 allow blocks in them, required or optional
78 - Reorganize Unit Tests
79 - Refactor loop tests (esp. AttrDef_URI)
80 - Reorganize configuration directives (Create more namespaces! Get messy!)
85 - Non-lossy smart alternate character encoding transformations (unless
87 - Pretty-printing HTML, users can use Tidy on the output on entire page
88 - Native content compression, whitespace stripping (don't rely on Tidy, make
89 sure we don't remove from <pre> or related tags): use gzip if this is
