- <p><c>compile:forms/1,2</c> would crash when used in a
- working directory thad had been deleted by another
- process. (Thanks to Adam Lindberg for reporting this
- bug.)</p>

- <p>Dialyzer no longer crashes when there is an invalid
- function call such as <c>42(7)</c> in a module being
- analyzed. The compiler will now warn for invalid function
- calls such as <c>X = 42, x(7)</c>. (ERL-138. Thanks to
- Daniel Feltey for reporting this bug.)</p>

- Optimization of tuple matching has been slightly
- improved.</p>
- <p>
- Own Id: OTP-12951</p>
- </item>
- <item>
- <p>Five deprecated and undocumented functions in the
- module <c>core_lib</c> have been removed. The functions
- are: <c>get_anno/{1,2}</c>, <c>is_literal/1</c>,
- <c>is_literal_list/1</c>, and <c>literal_value</c>. Use
- the appropriate functions in the <c>cerl</c> module
- instead.</p>
- <p>
- Own Id: OTP-12979</p>
- </item>
- <item>
- <p>The pre-processor can now expand the ?FUNCTION_NAME
- and ?FUNCTION_ARITY macros.</p>
- <p>
- Own Id: OTP-13059</p>
- </item>
- <item>
- <p>The function mapfold/4 has been added to the
- <c>cerl_trees</c> module.</p>
- <p>
- Own Id: OTP-13280</p>
- </item>
- <item>
- <p>Bitstring comprehensions have been generalized to
- allow arbitrary expressions in the construction part.</p>
- <p>
- Own Id: OTP-13289</p>
- </item>
- <item>
- <p>The compiler will now produce warnings for binary
- patterns that will never match (example:
- <c>&lt;&lt;-1/unsigned&gt;&gt; = Bin</c>). </p>
- <p>
- Own Id: OTP-13374 Aux Id: ERL-44 </p>
- </item>
- <item>
- <p>The compiler will no longer put the compilation date
- and time into BEAM files. That means that two BEAM files
- compiled on the same computer from the same source code
- and compilation options will be identical.</p>
- <p>Note: If you want to find out whether a BEAM file on
- disk is different from the loaded code, compared the MD5
- value obtained from <c>Mod:module_info(md5)</c> with the
- MD5 value obtained from
- <c>beam_lib:md5(BeamFileForMod)</c></p>.
