  ......	@@ -1,3 +1,81 @@
  	1	v0.7
  	2
  	3	- Added support for multiple databases. More information is in the
  	4	documentation. (yariv)
  	5
  	6	- When a controller function returns a {replace, Ewc} tuple, ErlyWeb no longer
  	7	treats Ewc as a sub-component if it's returned from a main component.
  	8	This lets the component referred by Ewc to
  	9	return any value that a main component function can return
  	10	(e.g. phased_vars, ewr, etc). (yariv)
  	11
  	12	- Set a 3-second threshold on auto compilation to avoid excessive
  	13	directory scans when loading pages that trigger multiple requests
  	14	(for example, due to img/script/css tags). (yariv)
  	15
  	16	- Changed the arity of the 'phased' function to 3 from 2. ErlyWeb 0.7 expects
  	17	the last parameter to be a list of variables passed from the controller
  	18	function. The variables are passed using the {phased_vars, Vars} return
  	19	value, e.g.
  	20
  	21	index(A) ->
  	22	{response, [{phased_vars, [{title, <<"sample page title">>}]},
  	23	{body, Body}]}.
  	24
  	25	The app controller's hook/1 function can now be implemented as follows:
  	26
  	27	hook(A) ->
  	28	{phased, {ewc,A}, fun(Ewc, Data, PhasedVars) ->
  	29	{ewc, html_container, [A, {data, Data},
  	30	proplists:get_value(title, PhasedVars)]}}.
  	31
  	32	This tells ErlyWeb to pass the value of the 'title' property as the last
  	33	parameter to html_container. (yariv)
  	34
  	35	- Added the {last_compile_time, auto} compilation option, which tells ErlyWeb
  	36	to only compile the files that have changed since the last compilation.
  	37	(ketralnis)
  	38
  	39	- Added an automatic check for the existence of expected foreign key fields
  	40	in related modules during compilation. This can be disabled by adding the
  	41	{skip_fk_checks, true} compilation option. (yariv)
  	42
  	43	- erlydb_base:save() now avoids setting 'null' values of properties when
  	44	executing INSERT statements. (yariv)
  	45
  	46	- Added the ability to override the join table names and use aliases for
  	47	related modules in many-to-many relations. E.g.
  	48
  	49	person.erl:
  	50
  	51	relations() ->
  	52	[{many_to_many,
  	53	[{painting, [{relation_table, creation_person},
  	54	{alias, creation}]}]}].
  	55
  	56	Then you can get the related paintings for a 'person' record as follows:
  	57
  	58	person:creations(Person).
  	59
  	60	This uses the 'creation_person' table to look up the related creations. (yariv)
  	61
  	62	- {encoding, charset_atom} in Options list of erlydb:start/2 that turns on
  	63	charset support over mysql connections. This allows us to support utf8,
  	64	for example. The default is to have no explicit encoding spec at all
  	65	(mysql server chooses latin1 by default.) (haoboy)
  	66
  	67	- {pool_size, N} in Options list of erlydb:start/2 that starts N mysql
  	68	processes in the process pool. The default value is to start only one.
  	69	(haoboy)
  	70
  	71	- erlyweb:create_component now takes options in the form of proplists, to
  	72	allow choice between on/off for magic, model and ErlTL files. (cowmoo)
  	73
  	74	- Added the {erlydb_timeout, Timout} compilation option to set the timeout
  	75	for SQL queries (currently only works with MySQL). (yariv)
  	76
  	77	- A bunch of bug fixes. (yariv)
  	78
  1	79	v0.6.2
  2	80
  3	81	- Fixed the app controller hook/1 return value handling, letting you return
