Since July 1994 Lie was integrating libwww and CSS and helping Raggett. In October 1995, Yves Lafon joined the team for a year to provide support for HTML form and style sheet development.
Despite its time of development, Arena is in certain areas a relatively modern browser; because it functioned as a testbed, it saw the implementation of new technologies long before they became mainstream, e.g. CSS. Arena implemented many elements of the HTML3 and HTML3.2 specification including math elements that were deprecated in HTML4, HTML tables, and experimental style sheets.
The W3C published 5 versions of the Arena beta-1 between 27 November 1995 and 8 February 1996 improving 16-bit operating system support and reimplementing CSS (which was still a Working Draft).
The W3C and the INRIA, a French national research institution, gave additional funding to develop CSS. To better implement and write CSS, an experimental style sheet for Arena was developed. On 22 May 1996, the W3C announced that Amaya will replace Arena as their new testbed and that the W3C was looking for a new maintainer because the W3C did not have the resources for two testbeds.
Beta-2 had two builds (beta-2a: 28 February 1996 and beta-2b: 21 March 1996) and introduced a new API for communicating with other applications. Also, the internal component libwww was updated to version 4. OMRON Corporation developed an internationalized version that could display Chinese, Korean and Japanese characters in one page. OMRON's Arena supports both ISO-2022 and Unicode. It is able to guess the charset parameter automatically if charset parameter isn't specified in Content-Type field.
Beta-3a released on 14 August 1996 and Beta-3b released on 16 September 1996 introduced support for the Linux operating systems on m68k and DEC Alpha. CSS 1 support was enhanced and the internationalized version was also updated. Between the two beta-3 releases the W3C was already looking at a new testbed and switched later to the Amaya browser. Beta-3 was the last involvement of the W3C in the development of Arena. On 17 February 1997, Yggdrasil Computing took over the role of developing the browser.
On 17 February 1997, the W3C approved Yggdrasil to coordinate future development of Arena. Development was taken over by Yggdrasil, with the idea to turn Arena into an open source X Window System browser licensed under the GNU General Public License. Yggdrasil licensed an X emulator from Pearl Software to port Arena to Windows, although these builds were never released. Yggdrasil did not provide any official binaries at this time, because they did not want to expand the community with alpha-quality software. Although users would be able to run Arena by compiling it from the published source code, volunteers created unofficial finished binaries. Yggdrasil had planned to implement browsing features that were already standard in competitive web browsers, which resulted in the new bookmarks feature in version 0.3.18 on 7 April 1997.
Development stopped in late 1998, with the final release being on 25 November 1998. The W3C did not consider demonstration projects to be high priority, and thus, the Arena browser was entirely shut down in favor of outside Linux-community development.
Although Arena ran well, there were inconsistent reports about the speed of Arena.
The biggest problems were that Arena couldn't handle forms, and that the PNG support was broken from version 0.3.07 on. Earlier Arena releases had full alpha-channel support, but only with using Arena's own "sandy" background pattern. The animated GIFs extension – presented by Netscape in March 1996 – did not work properly.
Other problems included rendering problems with tables, and the lack of integration of so-called extended HTML code, i.e. the <BG COLOR>-tag and the <DIV ALIGN>-tag.
Earlier versions of Arena (until 0.3.26 (01.06.97)) did not support the email MIME.
