5 0.7.3 - More bugs fixed
6 =========================
7 - A bug in the debug-system has been fixed: Data::Dumper would not be
8 loaded, though it might be neccessary in the selected debug-level.
9 - A bug with the disabling of persistency has been fixed. Thanks to qMax.
13 0.7.2 - Potential bug fixed
14 =============================
15 - The modules have been moved and rename, since a conflict with other
16 installed modules could appear in old versions of perl (<= 5.005).
22 - A bug in the persistency-code has been fixed: If the persistency-file
23 had to be created no checksum was included causing it to be overwritten
24 with the next run. The second run did set the checksum which is
25 propably why noone complained about this..
29 0.7.0 - Persistent data is here
30 =================================
31 - yaala now dumps it's data into a file and may use it in subsequent
32 runs. This way you don't have to keep all your old logfiles.
34 - A tiny fix allows yaala to run under Microsoft Windows.
38 0.6.8 - Workaround implemented
39 ================================
40 - A workaround for what seems to be a bug in some versions of Perl 5.8
45 0.6.7 - Some more cosmetics
46 =============================
47 - yaala now changes into it's own directory before execution. This is
48 useful for cron-scripts and the like.
50 - The config option ``print-graphs'' has been added for two reasons:
51 a) People who have GD::Graph installed can prevent yaala from
52 generating graphs now.
53 b) People who do neither have GD::Graph installed nor read the readme
54 will hopefully find this option and will get a detailed error
61 - A bug which would not let ``host_width'' to be set to zero (infinite
62 length) has been fixed. Thanks to Rafael Santiago for reporting it.
66 0.6.5 - More aggregations
67 ===========================
68 - More than one aggregation can be selected. This works with both, the
69 Combined and the Classic output module.
71 - Elapsed time (from the squid logfiles) is now being printed in
74 - The y-Axis of graphs is plotted in percent of the total now.
78 0.6.4 - Don't die on me, man!
79 ===============================
80 - yaala doesn't die anymore, if you select more than three fields with
81 the combined output module. An error message is printed instead.
83 - Empty cells are not printed any longer by default when using the
84 Classic output. You can re-enable this behavior with a config-option.
90 - Chimera has been renamed to Camino; MultiZilla and Safari have been
93 - The sub-indizes in the Classic output now provide a bit more
96 - A robots-metatag has been added to prevent search engines from indexing
101 0.6.2 - New/Old parser and bugfixes
102 =====================================
103 - The (old) bind9 parser has been fixed and works fine.
105 - A parser for the "xferlog" (used by wu-ftpd, proftpd and maybe other
108 - Selections with where-clauses should work better now.
112 0.6.1 - The return of the graphs
113 ==================================
114 - Support for GD::Graph is finally back again. yaala checks wether
115 GD::Graph is installed or not and behaves accordingly. You don't have
118 - All tables now print percentages as well.
120 - A parser for postfix entries in the maillog has been added.
122 - A bug in Data::Setup has been fixed. It wasn't possible to select more
123 than three keys with the Classic output module, which is perfectly
128 0.6.0 - New code, less bugs, less features
129 ============================================
130 - Huge parts of yaala's internals have been rewritten. The data-storage
131 is completely new and works better than in the 0.5.x line.
133 - General code cleanup. A lot of variables have been renamed.
135 - The debug-system has been unified.
137 - The Classic-output plugin emulates the ``old'' (0.4.x) output.
141 0.5.4 - Patches by qMax
142 =========================
143 - Input Module for method file:// has been added.
147 - Changes in qmax.css
151 0.5.3 - Reverse lookups
152 =========================
153 - Ability of reverse lookups has been added.
155 - Browsers and OSes are recognized better. The code should also be faster
160 0.5.2 - Now comes the command line
161 ====================================
162 - Every option from the config file has been made available from the
165 - The recognition of Windows 2000 has been fixed.
169 0.5.1 - Changes in config-reading and -parsing
170 ================================================
171 - config-reading and -parsing have been moved out of the main program and
172 into lib/Config.pm. Modules have been updated.
174 - The config syntax has changed slightly. See POD in lib/Config.pm
176 - webserver.config has been created.
178 - A bug in lib/parser/Ncsa.pm has been fixed.
180 - WebserverTools::detect_referer has been rewritten.
184 0.5.0 - yaala in the metamorphosis
185 ====================================
188 - Modules use the Exporter mechanismn now to import subroutines and
189 variables. Renamed modules in the process.
191 - Output is nearly XHTML kompliant. I'm working towards total XHTML 1.1
194 - Added logo.png, dot-dark.png, dot-light.png
196 - Removed logo.gif, dot0.gif, dit1.gif
198 - Added new stylesheet and set as default. The old stylesheet has been
199 renamed to "qmax.css"
201 - Graphics cannot be generated with this release. This option might come
202 back in some later release.
204 - Recognition of nimbda/codered attacks has been removed.
206 - few obvious bugs found but not yet fixed. See TODO.

232 comand line parameters to yaala, processing batch reports,
236 Contains *.gif and style.css - a thin cyan document style.
239 Default directory for reports.
240 I suggest to do not use html to avoid occasional remove of
241 *.gifs and style.css.
242 Actually, 'reports' should be symlink to some www directory.
245 Placed all (new) modules here.
248 Placed all old modules there.
251 Directory for parser modules.
252 TODO: parsers should pass month/date/time as UNIX-time
253 to make them properly sorted and formated.
254 Currently they should work w/out i18n handling
258 A pair of common output utilities.

328 0.4.2 - Added BIND9 support
329 =============================
330 - David Augros sent me a parser for BIND9 logfiles which I added.. Easy
331 tasks get done quick ;)
335 0.4.1 - security hole fixed
336 =============================
337 - An exploidable "bug" was fixed: It was possible to fake the referer to
338 contain HTML and/or JavaScript code which would show up in the generated
339 file(s) and eventually would be interpreted by the browser.
340 Thanks to Liviu Daia (Liviu.Daia@imar.ro) for the hint :)
344 0.4 - netacct and wnserver support
345 ====================================
346 - Two new parsers provide netacct and wnserver support.
347 Thanks to M. Feenstra for the wnserver support.
349 - The parser modules now have to initialize their data structure before they
350 start parsing. This allows for different types of logfiles to be supported.
351 The data-structures understood are:
352 count: Count each appearance of a unique value (eg. Browser, Date, etc)
353 sum: Build the sum of all the (numeric) values. (eg. Package Count)
354 byte: Basically the same as sum, but print as a byte-value
356 - Use of CSS (Cascading Style Sheets) in the HTML output. Results are smaller
357 files and the source is easier to read.
359 - You can specify a directory to create the output files in.
360 Be sure to copy logo.gif, dot0.gif and dot1.gif into this directory!
364 0.3 - Clean(er) code and squid support
365 ========================================
366 - The modules are now a lot cleaner and easier to understand. Various routines
367 have been moved and renamed so the namespaces are used in a more organizing
370 - There's a new input (parse) module for squid logfiles.
372 - The routines which save the data in a huge hash have been altered so they
373 don't depend on the type of data that is parsed at all. This was neccessary
374 in order go get squid to work.
376 - The graph module now generates PNG graphics; it's configuration hash was
377 moved into the main configuration.
379 - The main page has some stats about CodeRed and and Nimba attacks now. You may
380 choose to not include these requests in your stats..
382 - Correction of some regexps and therefore (hopefully) a better performance.
386 0.2 - More modules - more comfort
387 ===================================
388 - The structure is now _very_ modular
390 - A config file makes customization really easy
392 - Apache's access-logs and NCSA-conform logfiles now understood
394 - Another module provides another look (Top10)
396 - CHANGELOG looks nicer ;)
398 - Some changes in the makegraph.pm make the graphs look a lot better now.
402 0.1 - Initial version
403 =======================
406 - Parsing of multiple files
408 - Support for apache's combined-log-format
410 - Modular structure provides an easy way to code support for other formats.
