    … …  
    161157= Does WP Roids work on NGINX servers? =
    162158
    163 Maybe. [See this support question](https://wordpress.org/support/topic/nginx-15)
     159Yes, it uses a fallback for non-Apache configurations
    164160
    165161= Does WP Roids work on IIS (Windows) servers? =
    166162
    167 Probably not
    168 
    169 == Under The Hood ==
    170 
    171 WP Roids decides which Pages and Posts are suitable for caching and/or minification of HTML, CSS & Javascript.
    172 
    173 For HTML caching, image compression, and minification of CSS & JavaScript, the rules generally are:
    174 
    175 - User is NOT logged in ~ might change this in future, Phil
    176 - Current view IS a Page or Post (or Custom Post Type)
    177 - Current view is NOT an Archive i.e. list of Posts (or Custom Post Types) ~ might change this in future, Phil
    178 - Current view has NOT received an HTTP POST request e.g. a form submission
    179 - Current view is NOT WooCommerce basket, checkout or "My Account" page
    180 
    181 If any of the above rules fail, WP Roids will simply just minify the HTML output. All else gets the CSS & Javascript combined and minified (and requeued), then the Page/Post HTML is minified and a static `.html` file copy saved in the cache folder.
    182 
    183 The cache automatically clears itself on Page/Post changes, Theme switches and Plugin activations/deactivations
    184 
    185 WP Roids can also detect if you have manually edited a Theme CSS or JavaScript file and will update iteself with the new versions
     163Yes, it uses a fallback for non-Apache configurations

     366
     367- **Fixed:** CSS and Javascript minifying and enqueuing had issues with:
     368    * Some inline items were being missed out or rendered improperly
     369    * Absolute paths to some assets such as images and fonts loaded via `@font-face` were sometimes incorrect
     370    * Some items were queued twice
     371    * Some items were not queued at all!
     372   
     373- **Fixed:** HTML minification was sometimes removing legitimate spaces, for example between two `<a>` tags
     374   
     375- **Fixed:** Caching function was sometimes running twice, adding unecessary overhead
     376   
     377- **Improved:** Some `.htaccess` rules
     378- **New:** Function checking in background `.htaccess` content is OK, with automatic/silent reboot of plugin if not

     380
     381= v1.3.6 =
     382

     386
     387- **Fixed:** Regex to remove inline JS comments was failing if no space after `//`
     388- **Imprevement:** Compatability check when activating new plugins. On failure automatically deactivates WP Roids and restores `.htaccess` file
     389
     390= v1.3.4 =
     391
     392 - **Fixed:** `.htaccess` rewritebase error, was killing some sites dead AF, sorry

     407
     408= v1.2.0 =
     409
     410- **Fixed:** Combining and minifying CSS and Javascript **MASSIVELY IMPROVED!**
     411    * For CSS, now deals with conditional stylesheets e.g. `<!--[if lt IE 9]>`, this was causing a few hiccups
     412    * For Javascript, now deals with scripts that load data via inline `<script>` tags containing `/* <![CDATA[ */`
     413    * Minification process now does newlines first, then whitespace. Was the other way around, which could cause issues
     414
     415= v1.1.4 =
     416
     417- **Fixed:** Sorry, I meant site domain !== FALSE. I'm an idiot, going to bed
     418
     419= v1.1.3 =

     427
     428= v1.1.1 =
     429
     430- **Fixed:** Encoding of `.htaccess` rules template changed from Windows to UNIX as was adding extra line breaks

     434= v1.1.0 =
     435
     436- "Flush Cache" links and buttons added
     437- Five minutes applied to browser caching (was previously an hour)
     438- Whole HTML cache flush on Page/Post create/update/delete, so that home pages/widgets etc. are updated
     439- **Fixed:** PHP Workaround for hosts who struggle with basic `.htaccess` rewrites :/ #SMH
     440- **Fixed:** Additional checks before editing `.htaccess` as sometimes lines were being repeated, my bad
     441- **Fixed:** For you poor souls who are hosted with 1&1, a bizarre home directory inconsistency
     442- **Fixed:** Scheduled task to flush HTML cache hourly wasn't clearing properly on deactivation
