Per our documentation for both Git and SVN, users should have the option to specify changeset to exclude based on regex.

As you can see from the screenshot, this is not the case.
The page source even exists when examining the page, but it doesn't seem to render:
<fieldset class="dependsOnselectedRepository showOnnullRepository" style="display: none;">
<div id="fieldArea_createRepository_changeset_filter_pattern_regex" class="field-group">
<label for="createRepository_changeset_filter_pattern_regex" id="fieldLabelArea_createRepository_changeset_filter_pattern_regex">Exclude changesets</label>
<input type="text" name="changeset.filter.pattern.regex" value="" id="createRepository_changeset_filter_pattern_regex" class="text ">
<div class="description" id="createRepository_changeset_filter_pattern_regexDesc">A <a href="http:>regular expression</a> to match the commit messages to be excluded.</div>
</div>
</fieldset>
