|
| 5 | ## 5.2.0 - 2017-12-08
|
| 6 | ### Added
|
| 7 | - Added ability for the prerender server to restart Chrome due to some connection issues we've been seeing after a server is running for a few hours.
|
| 8 |
|
| 9 | ## 5.1.1 - 2017-12-08
|
| 10 | ### Changed
|
| 11 | - Chrome re-uses the original request ID on a redirect so we are saving off the fact that we saw a redirect to make sure we return a correct 301
|
| 12 | - Changed dependencies from ^ to ~ to make the semver more specific
|
| 13 |
|
| 14 | ## 5.1.0 - 2017-12-06
|
| 15 | ### Added
|
| 16 | - Added removal of `<link rel="import" src="">` tags after the page is done loading to the `removeScriptTags` plugin. Imported HTML can have script tags in it, and since it's already been rendered to the page we can safely remove it when running that plugin.
|
| 17 |
|
| 18 | ## 5.0.3 - 2017-11-29
|
| 19 | ### Added
|
| 20 | - Added `if (window.customElements) customElements.forcePolyfill = true`, `ShadyDOM = {force: true}`, and `ShadyCSS = {shimcssproperties: true}` to fix Polymer app rendering.
|
| 21 |
|
| 22 | ## 5.0.2 - 2017-11-20
|
| 23 | ### Changed
|
| 24 | - Added back `res.setHeader` for plugins to use

| 28 | - Set `renderType` to `html` for non "/render" endpoint
|
| 29 |
|
| 30 | ## 5.0.0 - 2017-11-15
|
| 31 | ### Added

|
| 35 | - Added ability to request jpg and png screenshots
|
| 36 | - Added ability to request pdf export of a page
|

|
| 38 |
|
| 39 | ### Changed
|
| 40 | - Removed PhantomJS and all references to it
|
| 41 | - Removed old event types: `beforePhantomRequest`, `onPhantomPageCreate`, `afterPhantomRequest`, `beforeSend`
|
| 42 | - Removed In Memory Cache (moved to new repo)
|
| 43 | - Removed S3 HTML Cache (moved to new repo)
|
| 44 | - Removed Prerender server options that are no longer needed: `workers`, `iterations`, `softIterations`, `cookiesEnabled`, `pageDoneCheckTimeout`, `resourceDownloadTimeout`, `jsTimeout`, `noJsExecutionTimeout`, `evaluateJavascriptCheckTimeout`

|
| 48 | ## 4.4.1 - 2016-12-28
|
| 49 | ### Changed
|
| 50 | - Whoops. Make sure `shouldEncodeURLBeforeBrowserFetch` defaults to true.
|
| 51 |
|
| 52 | ## 4.4.0 - 2016-12-28
|
| 53 | ### Added
|
| 54 | - Added `shouldEncodeURLBeforeBrowserFetch` to allow projects that use prerender to determine whether they want to call `encodeURI` on the URL before fetching it in PhantomJS. Useful for some URLs that might have encoded slashes in them, since encoding them further would cause incorrect behavior.
|
| 55 |
|
| 56 | ## 4.3.1 - 2016-08-25
|
| 57 | ### Changed
|
| 58 | - Fixed issue where PhantomJS crashed and then disposing caused bad phantomjs state
|
| 59 |
|
| 60 | ## 4.3.0 - 2016-08-04
|
| 61 | ### Changed
|
| 62 | - Bumped all dependency versions to latest
|
| 63 |
|
| 64 | ## 4.2.0 - 2016-08-04
|
| 65 | ### Added
|
| 66 | - Added ability for cluster master to kill last known phantomjs pid for a worker if the worker dies (preventing orphaned phantomjs instances)
|
| 67 | ### Changed
|
| 68 | - Better terminating for cluster workers
|
| 69 |
|
| 70 | ## 4.1.0 - 2016-07-27
|
| 71 | ### Added
|
| 72 | - Added NUM_SOFT_ITERATIONS to try to kill phantomjs and reclaim memory when no requests are in flight. This should be set to a low number (1-10) so that PhantomJS can be restarted often when it isn't doing anything else. NUM_ITERATIONS should still be set to something like 40-50 to make sure to force kill PhantomJS even if a request is in flight.
|
| 73 | - Added clearing of memory cache to prevent PhantomJS from returning a 304
|
| 74 | ### Changed
|
| 75 | - Fixed issue where prerender-status-code set to `200` was causing the page to skip being cached
|
| 76 | - Fixed an issue where we weren't using the correct pid when trying to force kill PhantomJS.
|
| 77 | - Moved clearing of memory cache and local storage to before the page loads instead of after. This will prevent edge cases that could cause a 304.
|
| 78 |
|
| 79 | ## 4.0.10 - 2016-06-01
|
| 80 | ### Changed
|
| 81 | - Fixed issue where S3HtmlCache was calling next() before finishing saving to the cache
|
| 82 |
|
| 83 | ## 4.0.9 - 2016-05-08
|
| 84 | ### Changed
|
| 85 | - Fixed issue where we were calling `hasOwnProperty` on a `querystring` that no longer had Object on it's prototype chain
|
| 86 |
|
| 87 | ## 4.0.8 - 2016-03-24
|
| 88 | ### Changed
|
| 89 | - Fixed issue where a webpage calling window.close would cause Prerender to be unable to shutdown PhantomJS properly
|
| 90 |
|
| 91 | ## 4.0.7 - 2016-03-22
|
| 92 | ### Changed
|
| 93 | - S3 cache plugin was incorrectly saving non-200 status code responses to the cache
|
| 94 |
|
| 95 | ## 4.0.6 - 2016-03-09
|
| 96 | ### Changed
|
| 97 | - preserve phantom arguments when server is restarting
|
| 98 | - use default when phantomArguments is empty
|
| 99 |
|
| 100 | ## 4.0.5 - 2016-02-29
|
| 101 | ### Changed
|
| 102 | - prevent multiple phantomjs instances from being started with low number of iterations
|
| 103 | - try to check to see if phantomjs has actually been disposed. if not, force kill it.
|
| 104 |
|
| 105 | ## 4.0.4 - 2016-02-18
|
| 106 | ### Changed
|
| 107 | - added engines to package.json and fixed possible bug in checking options passed in
|
| 108 | - prevent weird hangup on error setting a header with a newline
|
| 109 | - make sure we catch any errors thrown from phridge and continue
|
| 110 | - kill workers (and phantomjs) on SIGTERM
|
| 111 |
|
| 112 | ## 4.0.3 - 2016-02-12
|
| 113 | ### Added plugin to send a header of X-Prerender: 1 with every request
|
| 114 |
|
| 115 | ## 4.0.2 - 2016-02-12
|
| 116 | #### Now using PhantomJS version 2.1
|
| 117 | ### Changed
|
| 118 | - Changed `PHANTOM_CLUSTER_NUM_WORKERS` to `PRERENDER_NUM_WORKERS` in server.js
|
| 119 | - Changed `PHANTOM_WORKER_ITERATIONS` to `PRERENDER_NUM_ITERATIONS` in server.js
|
| 120 | - Switched from `phantomjs-node` bridge to `phridge`
|
| 121 | - All Prerender plugins that access PhantomJS need to be rewritten to support new [phridge](https://github.com/peerigon/phridge) integration.
|
| 122 | For example, change this:
|
| 123 | ```
|
| 124 | req.prerender.page.set('onConsoleMessage', function(msg) {
|
| 125 | console.log(msg);
|
| 126 | });
|
| 127 | ```
|
| 128 | to this:
|
| 129 | ```
|
| 130 | req.prerender.page.run(function() {
|
| 131 |
|
| 132 | this.onConsoleMessage = function(msg) {
|
| 133 | console.log(msg);
|
| 134 | };
|
| 135 | });
|
| 136 | ```
|
| 137 | Please see [phridge](https://github.com/peerigon/phridge) for more info on how to interact with PhantomJS through `phridge`.
|
| 138 |
|
| 139 | ###Removed
|
| 140 | - Removed `PHANTOM_CLUSTER_BASE_PORT` since `phridge` doesn't start a webserve to talk to PhantomJS, so it's no longer needed.
|
| 141 | - Removed `PHANTOM_CLUSTER_MESSAGE_TIMEOUT` since `phridge` doesn't start a webserve to talk to PhantomJS, so it's no longer needed.
|
