From The Collaborative International Dictionary of English v.0.48 :

  Beta \Be"ta\, n. [Gr. bh^ta.]
     The second letter of the Greek alphabet, B, [beta]. See B,
     and cf. etymology of Alphabet.
     Note: Beta (B, [beta]) is used variously for classifying, as:
     (a) (Astron.) To designate some bright star, usually the
         second brightest, of a constellation, as, [beta]
     (b) (Chem.) To distinguish one of two or more isomers; also,
         to indicate the position of substituting atoms or groups
         in certain compounds; as, [beta]-naphthol. With acids, it
         commonly indicates that the substituent is in union with
         the carbon atom next to that to which the carboxyl group
         is attached.

From WordNet (r) 3.0 (2006) :

      adj 1: second in order of importance; "the candidate, considered
             a beta male, was perceived to be unable to lead his party
             to victory"
      2: preliminary or testing stage of a software or hardware
         product; "a beta version"; "beta software"
      n 1: the 2nd letter of the Greek alphabet
      2: beets [syn: Beta, genus Beta]

From The Jargon File (version 4.4.7, 29 Dec 2003) :

   /bay't@/, /be?t@/, /bee?t@/, n.
      1. Mostly working, but still under test; usu. used with ?in?: in beta. In
      the Real World, hardware or software systems often go through two stages
      of release testing: Alpha (in-house) and Beta (out-house?). Beta releases
      are generally made to a group of lucky (or unlucky) trusted customers.
      2. Anything that is new and experimental. ?His girlfriend is in beta? means
      that he is still testing for compatibility and reserving judgment.
      3. Flaky; dubious; suspect (since beta software is notoriously buggy).
      Historical note: More formally, to beta-test is to test a pre-release
      (potentially unreliable) version of a piece of software by making it
      available to selected (or self-selected) customers and users. This term
      derives from early 1960s terminology for product cycle checkpoints, first
      used at IBM but later standard throughout the industry. Alpha Test was the
      unit, module, or component test phase; Beta Test was initial system test.
      These themselves came from earlier A- and B-tests for hardware. The A-test
      was a feasibility and manufacturability evaluation done before any
      commitment to design and development. The B-test was a demonstration that
      the engineering model functioned as specified. The C-test (corresponding to
      today's beta) was the B-test performed on early samples of the production
      design, and the D test was the C test repeated after the model had been in
      production a while.

     Kristensen, Madsen , Moller-Pedersen &
     Nygaard, 1983.  Object-oriented language with block structure,
     coroutines, concurrency, strong typing, part objects,
     separate objects and classless objects.  Central feature is a
     single abstraction mechanism called "patterns", a
     generalisation of classes, providing instantiation and
     hierarchical inheritance for all objects including procedures
     and processes.
