Starting with v1.8 osTicket will require mysqli extension.

This reverts commit e818fd2c.

Turns out that the query to fetch a "short" list from MySQL is slower than
just running all the filter rules in PHP

Replace phone number on ticket owner update

Displaying field values on various pages and dialogs could result in cross
site scripting exploits.

Fixes osTicket/osTicket-1.8#296

Previously only the name, email, and phone number would be displayed on the
pop up dialog

Otherwise, you can't click on the custom form in the table view in order to
manage it.

Fixes osTicket/osTicket-1.8#276

Previously, the user information could only be modified on the ticket-view
page. For instance, if creating a new ticket for a user, no new information
could be added or modified on the user until after the ticket was created

Fixes osTicket/osTicket-1.8#281

Previously, advanced search was bugged in such a way that the advanced
search on a field without a `name` value would result in a hit of all the
tickets.

Fixes osTicket/osTicket-1.8#288

The check in DynamicFormEntry::getAnswers() will use the cached _values
array if it is not set to null. Previously, the ::save() method would set it
to an empty array.

Previously, new fields would never show up on the company info page

Change thread entry title bar to use more flexible layout using div's and
span's in hopes of avoiding unnecessary wrapping -- especially in the poster
name column..

Fixes #262

Again, fix issue where multiple mails fetched in the same fetch run will set
the user of each of the mails to the user of the first email fetched.

The previous patch neglected to pass the new $cache argument through the
inherited UserForm::getFields() function.

If two emails were fetched in the same timeframe, they may both be assigned
to the same user account.

Fixes oversize image display to be resized in both the ticket thread and
the redactor editor in (at least)

  * Ticket-view boxes
  * Client new-ticket form
  * Staff new ticket
  * Page add/edit
  * FAQ add/edit
  * Canned response add/edit

Fixes osTicket/osTicket-1.8#247

Previously, due to a bug in Ticket::getPhone(), the first digit of the
formatted phone number was displayed only. This patch will allow display of
the entire formatted phone number.

Fixes osTicket/osTicket-1.8#248

'where 1' and 'where 1=1' gives me hives...

If a ticket is currently unassigned and your respond to it, it's yours. If a
ticket is closed and later reopened due to a new message, the last
respondent will always be assigned if available at the time.

Include all validation erors

Unpack user data for filtering purposes for staff created tickets

- Remove Client form
- Provide name and email fields for cases where use is not selected (JS
issues)
