### 2.0.0: Apr 12 2000

- First public release of libxml2. If you are using libxml, it's a good idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially scheduled for Apr 3 the release occurred only on Apr 12 due to massive workload.
- The include are now located under $prefix/include/libxml (instead of $prefix/include/gnome-xml), they also are referenced by

- the updates includes:
  - fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly handled now
  - Better handling of entities, especially well-formedness checking and proper PEref extensions in external subsets
  - DTD conditional sections
  - Validation now correctly handle entities content
  - change structures to accommodate DOM
- Serious progress were made toward compliance, here are the result of the test against the OASIS testsuite (except the Japanese tests since I don't support that encoding yet). This URL is rebuilt every couple of hours using the CVS head version.

### 1.8.7: Mar 6 2000

- This is a bug fix release:
- It is possible to disable the ignorable blanks heuristic used by libxml-1.x, a new function xmlKeepBlanksDefault(0) will allow this. Note that for adherence to XML spec, this behaviour will be disabled by default in 2.x . The same function will allow to keep compatibility for old code.
- Blanks in <a> </a> constructs are not ignored anymore, avoiding heuristic is really the Right Way :-\
- The unchecked use of snprintf which was breaking libxml-1.8.6 compilation on some platforms has been fixed
- nanoftp.c nanohttp.c: Fixed '#' and '?' stripping when processing URIs

### 1.8.6: Jan 31 2000

### 1.7.1: Sep 24 1999

- The basic type for strings manipulated by libxml has been renamed in 1.7.1 from CHAR to xmlChar. The reason is that CHAR was conflicting with a predefined type on Windows. However on non WIN32 environment, compatibility is provided by the way of a #define .
- Changed another error : the use of a structure field called errno, and leading to troubles on platforms where it's a macro

### 1.7.0: Sep 23 1999

- Added the ability to fetch remote DTD or parsed entities, see the nanohttp module.
- Added an errno to report errors by another mean than a simple printf like callback
- Finished ID/IDREF support and checking when validation
