These are works in progress and somewhat shorthand, but may be useful. First are the Lasso 9 Issues that I've encountered upgrading sites from 8.6 to 9. And second are some notes about installing Lasso 9 on Ubunto 12 on AWS.

===============================================================Lasso 9 Issues

Undefined Variable in Conditional
Important - This change is subtle and requires some care to ensure that the change in behavior doesn't affect existing code.
Fails if var('x') is undefined since $x == null and null != ''
Examples:
if(var('x') == ''); ... /if;
if(var('x') != ''); ... /if;
Workarounds:
if(string(var('x') == ''); ... /if;
if(var('x') != null && var('x') != ''); /if;

[Protect] ... [/Protect]
Important - Must check every protect block.
Move handle block as first statement in container

Encoding Keywords
Error Msg: Unexpected: KEYWORD
Not supported
[var('x', -encodebreak)] -> [Encode_Break($x)]

Numerous Type Casting Issues
Error Msg: Definition Not Found: null->split(string)
field('name')->split(' ') -> string(field('name'))->split(' ')
field('name') >> ' ' -> string(field('name')) >> ' '
if field might be NULL cast to string before using string methods

Trailing Comma in array and map definitions
Only seems to cause a problem in some cases

Sloppy Local References
Error Msg: The local variable "lists" has not been defined
Change #lists to $lists

Skip Records
Error Msg: Definition Not Found: dsinfo->skipRows=(string) Candidates were: dsinfo->skipRows=(p0::integer)
-SkipRecords='10' -> -SkipRecords=10
-SkipRecords=integer(var('skip'))

[Date_Format]
Error Msg: Parser error. Character was not understood line: 284, col: 79
[Date_Format: (field: 'vote_date'), -Format='%b %_d, %Y']
-> [Date(field('vote_date'))->Format('%b %_d, %Y')]

[Content_Body]
Change $__http_reply__ to use [content_body]

[Content_Header]
Change $__http_header__ to use [content_header]
Does not support concatenation [content_header += 'x']
Does not support replacement [content_header('x')]

[Math_Range]
Must be written without keywords -min/-max
First parameter must be numeric
[math_range(integer(field('age')), -min=1, -max=100)]

$foo->isa(array)
Fix brain dead code
$foo->isa('array')

[Null(tag())]
Not supported
Wrote [Nil] which consumes output
define_tag('nil'); /define_tag;

[Lasso_Comment] ... [/Lasso_Comment]
Not supported
Wrote replacement
define_tag('lasso_comment', -container, -namespace=namespace_global); /define_tag;

[Session_Start]
Bug - Had to set -UseAuto=false to disable link decoration when using -UseNone

[File_Chmod]
Bug (Reported 9.2 and Fixed)
50:2 compat/compat.file.lasso
Error Msg: Definition Not Found: if(integer)

[Shell]
Update to:
http://www.lassosoft.com/tagswap/detail/Shell_9

OPTIMIZATIONS

String += -> ->append
Find: " ?\+= ?(['"].+);[ ]*\r"
Replace: "->append(\1);\r"
